Question

I'm in need of help in this one, Ideal gas law.

Molecular chlorine and molecular fluorine combine to form a gaseous product. Under the same conditions of temperature and pressure it is found that one volume of Cl_2 reacts with three volumes of F_2 to yield two volumes of the product. What is the formula of the product?

Answer 1

@madrockz :)

Answer 2

in this equation

1 Cl2 + 3 F2---> 2 ClxFy

those coefficients are in MOLE (or molecule) ratios. BUT for gases at the same temp and pressure, they are also VOLUME ratios.. why? PV = nRT, V = nRT/P. if RT/P = constant.. V1/n1 = V2/n2 --> n1/n2 = V1/V2..make sense? mole ratios = volume ratios

so.. what are x and y?
1 Cl2 + 3 F2---> 2 ClxFy

2 Cl's on the left.. x must = 1
6 F2's on the left. y must be 3

1 Cl2 + 3 F2---> 2 ClF3
