1- When heated, calcium carbonate decomposes to yield calcium oxideand carbon dioxide gas via the reaction

CaCO3(s)?CaO(s)+CO2(g)

Whatis the mass of calcium carbonate needed to produce51.0Lof carbon dioxide at STP?






2- Butane,

C4H10,is a component of natural gas that is used as fuel for cigarettelighters. The balanced equation of the complete combustion ofbutane is

2C4H10(g)+13O2(g)?8CO2(g)+10H2O(l)

At 1.00 atmand 23 ?C,what is the volume of carbon dioxide formed by the combustion of1.00gof butane?

The ideal gas law

PV=nRT

relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant R equals 0.08206 L?atm/(K?mol) or 8.3145 J/(K?mol). The equation can be rearranged as follows to solve for n:

n=PV/RT

This equation is useful when dealing with gaseous reactions because stoichiometric calculations involve mole ratios.
