Chemical Equations Write and Balance equations for the following reactions: Solid calcium phosphate reacts with sulfuric acid to produce aqueous calcium sulfate and phosphoric acid Copper reacts with nitric acid to produce copper(II) nitrate, nitrogen dioxide gas and water. Butane reacts with oxygen to produce carbon dioxide and water vapor.
Stoichiometry Let’s look at the butane reaction once more: 2C4H10 + 13O2 → 8CO2 + 10H2O What do the coefficients represent? Stoichiometry is the use of these ratios to determine quantitative relationships b/w the species in a rxn. 0.500 mol of butane would produce how many mol of CO2? If 5.00g of butane reacts with an excess of oxygen how many grams of CO2 could be produced?
Stoichiometry If 5.00g of butane reacts with an 10.0g of oxygen how many grams of CO2 could be produced? How many grams of the butane would be left when the reaction is complete? How many dm3? If 7.91g of the CO2 are collected, what is the percent yield? Just for fun: When 50.0g of silicon dioxide is heated with 50.0g of carbon, 32.2g of silicon carbide is produced. The other product formed is carbon monoxide. -What is the percent yield of the reaction? -How many dm3 of carbon monoxide gas are produced? -How much excess reagent is left over?
