Stoichiometry and Ideal Gas Law Test

Question 1

Given these products;
ZnO+4CO2+5H2O
How much CO2 would be produced if 25gs of H2O were produced.

Answer 1

20 grams

Question 2

The step/conversion factor that must be included in every Stoichiometry T-Chart regardless of the units and final amounts, is the ______ step.

Answer 2

The mol ratio step

Question 3

At STP, ___ C and ___ atm will occupy ___ liters of volume.

Answer 3

0 C, 1.00 atm, 22.4 liters

Question 4

The way to recognize that a stoichiometry problem involves limiting reactants is that the information given in the word problem will include ____________.

Answer 4

Given specific amounts of two reactants in grams or mols.

Question 5

A Particle of ethylene is much larger than a particle of helium. Why doesn’t a mol of ethylene occupy a larger volume than a mol of helium at STP.

Answer 5

The size of a mole of gas isn’t relevant when determining the volume, because at the same pressure and temperature the gases will drift out to occupy equal amounts of volume.
