Find the volume of oxygen.
1.Calcium carbonate forms limestone, one of the most common rocks on Earth. It also forms stalactites, stalagmites, and many other types of formations found in caves. When calcium carbonate is heated, it decomposes to form solid calcium oxide and carbon dioxide gas.
CaCO3(s) →CaO(s) + CO2(g)
How many liters of carbon dioxide will be produced at STP if 1.29 kg of calcium carbonate reacts completely?
2.What volume of oxygen is needed to completely combust 2.07 L of methane gas (CH4)?
