It depends on the state.  Most are 0.08 but some are 0.1.

Alcohol intoxication will vary depending a ton of different factors.  Some of these include: your height and weight, how much you ate before you drank as well as when you last ate, your mood before you drank, how fast or slow your metabolism is, other medication you might be taking, amount of alcohol in the drinks, size of the drinks, how fast you drank them, etc.  \n\nHowever, you can try this chart to do an online assessment of what your blood alcohol content would be.  It is only meant as a gauge and is not  capable of being completely accurate, as the other factors I mentioned above also have an effect on your BAC.  It also gives you a chart that is great for reference.\n\nhttp://www.ou.edu/oupd/bac.htm\n\nThe good news in your case is that alcohol does leave your system pretty quickly, usually within 24 hours (depending on how much you had to drink).

nope you dont necessarily have to take (or fail) a sobriety test before you get breathalized. keep in mind, though, that you DONT have to take a breathalizer either. if youre caught in that situation, just refuse the test (you can even refuse the sobriety test). youre license may get suspended for refusing to take the test, but it'll be harder for the DA to prosecute you for a DUI or DWI if they dont have any hard evidence (which a breathalizer could produce). oftentimes when people do this the DA is forced to either drop the case or prosecute a lesser charge (like reckless driving). \n\nbottom line: KNOW YOUR RIGHTS. law enforcement can sometimes make you feel like you have to do things (like take a breathalizer), but you dont. they have the right to scare you, but you have the right to refuse!

if your conditions of release or your p.o. indicates you cannot drink, thats exactly what it means.  if you are ordered to report for a random breath test and fail, they don't care where you have been drinking, you are in violation and most likely be will revoked and booked back into jail where you started out in the first place.

Yes it can be checked through blood test and also  breathalyzers.

I dont understand what r u doing with "p*v/t"; but if assume ideal gas behavior, PV = nRT, so P = nRT/V [n is number of moles, R is ideal gas constant, T is temperature, V is volume of the flask, P is the pressure]

I wonder what's the end use requirement.\n\nIf there is any available in a lab sample size, then it should be available from one of the Laboratory & equipment supplies companies.\n\nIs this to be used raw or in some kind of cast and glazed form?\nI have heard many people are allergic to traces or sulphites even in a few ppm range ( that could be inhaled or ingested , so be careful ).

in no way whatsoever ( it is not accurate enough for court ) sorry for the pause - at work\n\neven if we ever get a test that is 100% accurate the effect will be minimal \n\nwe would not use it in crime solving ( self incrimination ) nor in business ( right to privacy )

enantiomeric excess (%) = \n(specific rotation of the mixture/ specific rotation of the pure enantiomer in excess)*100 \n\nor \n\nenantiomeric excess (%) = \n( | [enantiomer 1] - [enantiomer 1] | ) /([enantiomer 1] + [enantiomer 1] *100 \n\nwhere the square brackets indicate concentrations, and the | -- | in the numerator means "absolute value".

That could be determined by calculation based on the chemistry of the dissolve CO2, but that would become quite involved.  \n\nAnother way would be to measure the volume of CO2 given off by a known volume of Cola, and then factoring it up to he 2 L.  This could be done by collecting it into ann inverted test tube filled with water.  The CO2 would fill the tube and displace the water.\n\nOr else, guzzle a 2 L bottle, and measure the volume of the burp.

First you need to ask yourself if you have any reason to believe that measurements of nitrogen oxide [chemical formula -- Just say "NO"] emissions across different cars should be normally distributed.  Since this is a statistics problem, we assume that the answer is yes.\n\nThen you compute the sample mean (the sum of those seven measurements, divided by seven) and the sample variance (the sum of (x - sample mean)^2 for those seven measurements x, all divided by six).  The sample standard deviation is then the square root of the sample variance.\n\nFinally, you look up on your table or with your calculator or wherever what "Z score" corresponds to 98% of the area under the normal pdf curve being between\n\n(mean - Z standard deviations, mean + Z standard deviations)\n\nThey want to know if that upper bound is less than 0.165 grams / mile [a peculiar mix of metric and non-metric units].\n\nThat's probably how they want you to solve it.  Compare that to the Bayesian approach (Google for it).

It's not the reaction times -- it's the crime itself you're punished for.\n\nDriving while intoxicated is a special case because there are special laws regulating alcholol and other intoxicant. But while it's easy to test for drug/alcohol use in an objective blood test, it's almost impossible to test for emotional or situational impairments.\n\nSo, driving while intoxicated can be punished by itself, separately, because there can be objective standards. But anything else can only be punished based on the objective results.

I agree; c) is the right choice.  The other units are used to measure:\n\na)  power ratio\nb)  pressure\nd)  pressure (again)

Not sure the level with which you are learning, so feel free to ignore the thermodynamics explanation.  If you just want to answer the question, select D.\n\nLike most test questions, there is not enough conditions specified and truly, we could choose several anwers, but only after making assumptions that less likely to be in the testers mind.  I will assume a high school or intro level college course because above that this should be challenged as too vague.\n\nUse logic to realize that answer choice C is not true. Evaluating the others we realize that A means only heat is given off when bonds form and B means heat is absorbed or added during the formation of bonds.  D means conditions exist in which either situation is possible and E means that final product is in a state that has a higher value for entropy.  This only holds true when both Temp and pressure of a system is held constant, but we will eliminate later as well.\n\nBasically a bond can occur when the system goes from a high energy state to a lower energy state.  Formation of bonds is essentially a chemical reaction.  The Gibbs Free Energy equation:\n\n (delta)G=(delta)H-T(delta)S\n\nT=temp of system in Kelvin\n(delta)H is the heat energy change\n(delta)S is the change in entropy (disorder)\n\ndefines whether a reaction will occur spontaneously or not.  (deltaG) must be negative for this to be true. So we will assume \nusing this equation and recognizing that (delta)H tells us exo or endothermic if it is positive or negative , examination of the possibilities of (delta)H and (delta)S,\n\nIf (delta)H is negative and (delta)S is positive the equation will result in a negative value for (delta)G which means a favorible condition exists for bonding to occur.  Therefore, the condition of (delta)H negative (energy leaves as heat - exothermic) is true.  We can thus eliminate answer choice B.\n\nIf the opposite is true and (delta)H is positive and (delta)S is negative, the result is (delta)G that is positive and therefore not spontaneous.  no reaction or bonding occurs.\n\nIf both (delta)H is positive and (delta)S is positive, only a large enough (delta)S will overcome the positive (delta)H in the equation.  So if both are positive and T(delta)S is greater than (delta)H the bonding will occur.  Therefore, when (delta)H is positive (endothermic) the reaction may occur as well.  We can thus eliminate choice A.\n\nWe have shown that C is a true statement because conditions can be met in which the reaction is both exo or endothermic.  However, please note that in both conditions (delta)S is also positive, indicating an increase in entropy.  For the most part any system will always trend toward an insrease in entropy.  \n\nThe question then arises, what happens when (delta)S is negative (decreased entropy) and (delta)H is negative.  For most situations T(delta)S will be large enough to create a positive (delta)G from our equation.  In very rare cases will (delta)H - T(delta)S result in a negative answer.  However, the equation shows this as a possibility when (delta)G= large negative (delta)H - T x small negative (delta)S => large negative # minus a smaller negative => larger negative + smaller # = negative.  (Hope you follow my train of thought).  Therefore in the right situation - (delta) can be negative and bonding/reaction can occur when entropy decreases.  Eliminate E and C is the correct answer.\n\nCareful what you ask for.  Wikipedia site looks pretty informative but very detailed and you have to use a few different pages.

It depends on the test that is being performed. Some reported as micrograms per deciliter, parts per million, or an actual count of cells. Some tests, like blood alcohol are in a grams percent report.\n\nAgain, depends on the test being run and the machine that is performing the test. You can search on line for normal values for most blood tests. If you have the copy of it in your hand, it usually gives the normal values next to your level.

Not much.  Why would they?  They don't even cover up the booze on your breath from people smelled by people, why would it affect the test?\n\nSeriously, I have a chemistry degree and I ask, why would it?

You might take a look at information on peak flow as well which is a common test for the "quality" of your lungs with Asthma ( I am 25% down) \n\nTables exist for testing in the workplace for lung capacity\n\nhttp://www.biologycorner.com/worksheets/lungcapacity.html\n\nthis rocks for kids! ...careful with over inflated balloons they are high pressure if the mouth is used as a one way valve on inflation then opened!\n\nhttp://www.biologycorner.com/resources/BSA_formula.gif\n\nmight be all you need\n\nLONG TEXT FROM: \nhttp://emphysemafoundation.org/featurearticles.jsp\n\n Measuring Lung Capacity\n\nA simple device called a spirometer measures your lung capacity.  During this test you take a deep breath, as deeply as you can, and blow it out all at once into a machine that records airflow and capacity.  The total amount of air blown out of fully inflated lungs is called the vital capacity.  Since the air is forced out by your muscular effort, it is called forced vital capacity (FVC, newer term FEV6).  This test measures the useful size of your lungs.  The rate of airflow tells how open the air passages are and how well the lungs can empty, or how well their elasticity is functioning.  The lungs empty somewhat like an inflated balloon.  Remember how a flabby or overused balloon empties slowly and incompletely?  This is a lot like the lung with emphysema.  The airflow test is called the forced expiratory volume in one second, since this airflow is timed or measured over the first second of exhalation.  The symbol for forced expiratory volume in one second is FEV1.  These two tests, the FVC and FEV1, reveal all your doctor needs to know about your lung capacity and airflow.  These two numbers are somewhat similar to systolic and diastolic numbers in blood pressure readings.  We believe that knowledge of FVC and FEV1 is as valuable and important to health promotion as knowledge of blood pressure.  These tests measure your lung power, which is essential to your continuation and enjoyment of life.\n\nNormal values are based on age, sex, and height.  Younger and taller individuals have greater airflow and air volume than shorter or older people.  Men have slightly greater airflow and air volume compared with women of the same age and height.\n\nSelf-Testing-   Try It Yourself\n\nNormal lungs have large volume, and they empty quickly because airways are open and lungs are elastic.  You can do a little checking yourself with a stopwatch.  Take a full breath; hold if for one second.  Then, with your mouth open, blow out as hard and fast as you can.  Your lungs should be completely emptied – meaning that you can blow no more air out even though you try--  in no more than 4 to 6 seconds. \n\nIf one takes longer to blow out all the air, it means that airflow is obstructed or limited.  Today we use the term “limited” because this airflow reduction can be due to either a loss of lung elasticity (emphysema) or problems with airways (asthmatic or chronic bronchitis).  See how simple it is!\n\nUnfortunately, routine lung function tests have been accepted all too slowly.  No person would go for a complete check-up if the physician did not examine the eyes, ears, nose, throat, listen to the heart and lungs, feel the abdomen for any abnormal masses, and examine the genital, rectal, and pelvic areas.  All these are routine, and to supplement them, appropriate laboratory blood and urine tests are done, plus an electrocardiogram and, usually, a chest x-ray.  Unfortunately, none of these examinations or tests identifies early COPD.\n\nOnly spirometric measurements of the kind we have just described can identify the patient who is just beginning to develop a lung abnormality.\n\nWhen one considers that the disease process finally resulting in disability may go on for 20 to 30 years, doesn’t it make sense to identify the problem early and to take immediate corrective action?  The answer must be yes if you are to a enjoy a long happy life
