B) 1.50 mol
Since O2 and H2O are in a 1:2 ratio, multiply 0.75×2 = 1.50
Answer:
the water is diffrent because it is now a gas not a liquid
Explanation:
The answer would be E, it shows students how the different environments appear, since you can visually see it.
Answer:
the answer is A
Explanation:
I dont really have an explanation but hope it helps
The molar mass of the unknown compound is calculated as follows
let the unknown gas be represented by letter Y
Rate of C2F4/ rate of Y = sqrt of molar mass of gas Y/ molar mass of C2F4
= (4.6 x10^-6/ 5.8 x10^-6) = sqrt of Y/ 100
remove the square root sign by squaring in both side
(4.6 x 10^-6 / 5.8 x10^-6)^2 = Y/100
= 0.629 =Y/100
multiply both side by 100
Y= 62.9 is the molar mass of unknown gas
