equllibrum constant dosent have units, but what happens when you have a power of one of the concentrations ?

Hey I'm studying physical and chemical equilibrium too, currently.The answer is that it will definitely have units when the concentrations have different powers.Just try and work it out with the units and it will be very clear.

1 G, I dont see how it can be zero otherwise it would float off!\n\nOK call me an idiot...I have just read the other answers lol

Let u = e^x + 1.  Then du= ...\n\nHope that helps.

the first equ is balanced, b/c on the left side u have Pb-1, C-1 O-3 on the right side u have Pb-1 C-1 O-3 so since both side are equal it is balanced\n\nans for question 2 BeCl2 + 3O2------Be(ClO3)2\nBe-1                                  Be-1\nCl-2                                    Cl-2\nO-was 2 now 6                                     O-6

pi*(r^2)\n\nIt doesn't matter which unit you use, just make sure you're consistent.

(e^(cose^e+sin^e)/2)^pi\nhahaha ..just kidding

No. They do not share the same dimensions.\n\nYou can multiply them though.

You need to get your units in a consistent form.  I suggest changing the velocity of the electron to 2.5E6 m/s so when you divide it into c-----------WAIT A MINUTE!-----Yor formula is NOT right, because you're dividing a speed by a speed, which will give a dimensionless answer.  Wavelength is a LENGTH, so the answer must come out that way.  I forget the formula you're refering to, but what you've typed isn't it................

Units are arbitrary, but once chosen need to be kept as a constant reference to allow comparison of results over time. This is a challenge, because even things like measurement precision  change.\n\nThe original metre for instance was a reference bar of platinum held in Sevres, France - its length was originally chosen to be one ten millionth of the distance from the Equator to the North Pole on a line through Paris. Similarly for all other units.\n\nThese days, most units have been redefined in terms of unchanging physical phenomena that can be reproduced in any standards lab without the need for a special reference bit of metal. So the metre is now defined as the distance travelled by light in 1/299,792,458 seconds. This means it is a tiny bit different to the original metre but will never change.\n\nThe notable exception is mass. The kilogram is defined as being equal to the mass of the international prototype of the kilogram. This prototype is a lump of platinum iridium alloy held in Paris. The kilogram is the only SI unit based on a reference prototype.

Mix with a 0% solution in the relation 33:2\n\nSo use 2 units of your solution (like 2 liters) and 33 units of the 0% solution (like 33 liters).\n\nThat's all.

I think that's dalton's law.  Whoever came up with it, the pressure is additive.  So convert so everything is in the same units, multiply by the percent, add, and then compare to the answers.  I bet it's more fun than you predict.  Whooo!  Conversion factors!  I don't want to take that kind of enjoyment away, so get cracking!

For reaction aA <--> bB + cC, the Eq.constant K is defined as\n\nK = (B^b * C^c) / A^a\n\nSince in your equation a=b=c=1, and concentration for B=C, the equation simplifies to\n\nK = B^2 / A\n\nwith B=0.046 and A=0.454    (0.454=0.500-0.046)\n\nso K = 0.046^2 / 0.454 = 0.0047

Depends on which 'unit' you're talking about   :P

[V]=J/C=W/A=Kg.m^2/(s^3.A)\n\nFor experimental reasons A is the base unit and not C, you can not count electrons one by one, not yet probably soon

OH NOES THIS IS LIKE A MATH PROBLEM!!!! i can't handle any more variables :( sry.\n\n\nhahahaha.

The volume unit would be a cubic unit as it is 3-dimensional. It would depend on the unit of measure in the equation.\n\nThe calculation for volume of a cylinder is (pi) * radius^2 [squared] * height.\n\nOr out in English "Pi times the radius squared times the height"
