How is carbon dioxide and carbon dioxide concentration measured?
955757
CO2 is measured either by infrared spectroscopy or chemical reaction with hydrazine (N2H4).

First find the number of moles by dividing by the avogadro number, say n.\n\nSecond find the molecular weight of CO2, say M. This will give you the weight of one mole\n\nso\n1 mol CO2  gives you M g\nn mol CO2 gives you x g\n\nx = n * M.

This is called Base line correction.\nYour solvent may be having some absorption, or the impurities in it may be having some absorption..so to measure your compunds absorption exactly, you need to take the solvent (n whcih you are going to dissolve your compound later) and do this base line correction.\nIn a way you are telling instruments "NOT TO WORRY ABOUT THESE ABSORPTIONS"\n\nThats it\nYou got it?

There are two oxygen carrying mechanisms in the blood. One is dissolved oxygen in the plasma. The other is hemoglobin, the red colored stuff in the red blood cells. It combines with oxygen in the lungs, and releases it in the tissues, where it picks up CO2. CO2 also dissolves in the plasma, and both tend to give it up in the lungs. \n\nSaturation is a measure of how much oxygen is in the blood sampled as compared to the maximum possible. In hospitals, it is non-invasively measured by optical sensing through a finger tip. It's that little glowing clamp thing they stick on a finger. \n\nThis works because oxygen carrying hemoglobin is 'redder' than non-oxygen carrying hemoglobin. But it doesn't include the oxygen carried by the plasma, since plasma with oxygen isn't noticeably different in color than plasma with less oxygen in it. So this measurement isn't (quite) accurate since it's not really measuring all the oxygen present. \n\nBut this is clinically useful because it's a reasonable measure of what's really the point of bothering with oxygen saturation at all. some lung conditions interfere with the transfer of oxygen and CO2 in the lungs. Since the hemoglobin saturation participates in that transfer, how well it's been saturated can be used for practical clinical indications. We don't really need to know exactly what the oxygen saturation is, since, if it's good enough, that's all we need to know. Only if there's some major problem, will we need to know anything more detailed.

Does it show when the CO2 is collected?

first balance equation\nCH4 + 2O2 --> CO2 + 2H2O\n\nthen convert (look at balanced equation and use coefficients)\n3.28 moles O2 x 1 Mole of CO2 / 2 Moles O2 = 1.64 moles of CO2

-> 6CO2 + 6H2O     Carbon dioxide.

the rate of photosynthesis can be determined by measuring the rate of either O2 production or CO2 uptake. For right method to determine the rate of O2 produced during photosysnthesis refer the link.\nhttp://web.grinnell.edu/courses/bio/qubitmanual/Labs/PHS/pho.html.

most of the carbon dioxide gas is transported as bicarbonate in blood.(about 70 %).around 20 % as carbamino compound and rest 10% is transported in dissolved physical form.

If tha atomic mass of M is A, then the molecular weight is MW=2*A+60\n\nThe concentration of the M2CO3 solution is C=mole/V and since mole=mass/MW, C=mass/(MW*V)\n\nThen you do a titration for which we assume complete reaction and not reaching only the first end-point, so the reaction is\n\nM2CO3 + 2HCl -> 2MCl + CO2 + H2O\n\nTherefore 2*mole M2CO3=mole HCl =>\n2*C1*V1= C2*V2=>\n2*V1*mass/(MW*V) = C2*V2 =>\nMW= 2*V1*mass/(C2*V2*V)=\n=2*0.025*7.46/(0.1*0.027*1)\n=138\n\nand MW=2*A+60=138=> 2A=78 => A=39\n\nSo M, is potassium (K)

Simple one will be \nSunlight + Carbon dioxide (CO2) + Water (H2O)--> Glucose (C6H12O6) + Oxygen (O2).\nor \n6CO2 +12 H2O (light energy and chlorophyll) ---> C6H12O6 + 6O2\nRemember to use subscript whenever necessary.

ph meters are designed to check the power of Hydrogen in a substance. The scale runs from 1 (extreme acid) to 14 (extreme caustic). You cannot check the concentration of a a substance, such as how much acid or caustic is ion a solution. To find that, you have to titrate for the concentration.
