The heat from an acetylene torch is produced by burning acetylene (C2H2) in oxygen. 2C2H2(g) + 5O2(g) 4CO2(g) + 2H2O(g)

How many grams of water can be produced by the reaction of 27.0 g of acetylene with 47.0 g of oxygen? How many grams of the excess reactant will be leftover?

When 5.00 g of copper reacts with excess silver nitrate, silver metal and copper (II) nitrate are produced. Write the complete balanced equation and then determine the theoretical yield of silver in this reaction?

If 50.0 g of silicon dioxide is heated with an excess of carbon, 27.9 g of silicon carbide (SiC) along with some carbon monoxide are produced. Write the complete balanced equation and then determine the percent yield of silicon carbide in this reaction.

If 15.0 g of nitrogen reacts with 15.0 g of hydrogen, 10.5 g of ammonia is produced. Write the complete balanced equation and then determine the percent yield of ammonia in this reaction.

If 75.0 g of siderite ore (FeCO3) is heated with an excess of oxygen, 45.0 g of iron (III) oxide is produced with carbon dioxide. Write the balanced equation and determine the percent yield of iron (III) oxide in this reaction.
