Bottled propane is used in areas away from natural gas pipelines for cooking and heating, and is also the source of heat in most gas barbecue grills. Propane burns in oxygen according to the following balanced chemical equation.
C3H8(g) + 5 O2(g) 3 CO2(g) + 4 H2O(g)
Calculate the mass in grams of water vapor produced if 3.09 mol of propane is burned.
A mixture of CO, CO2 and O2 is contained within a 275 mL flask at 0C. If the total pressure is 780 torr, the CO has a partial pressure of 330 torr and the CO2 has a partial pressure of 330 torr, what is the partial pressure of O2?
Calcium carbide, CaC2, reacts with water to form acetylene. CaC2(s) + 2 H2O(l) C2H2(g) + Ca(OH)2(s) How many grams of water are needed to react with 473 g of calcium carbide?
how many grams of carbon are required to react with 1.5x10^25 atoms of hydrogen to form CH4
A 50.0-L stainless steel container was charged with 3.00 atm of hydrogen gas and 4.00 atm of oxygen gas. A spark ignited the mixture, producing water.
Im really confused about spectroscopy and need an introduction on what it is and what these types of problems mean.
