HELP!
1. In the reaction to create silver sulfide, silver reacts with sulfur as described by the following equation: 2Ag + S ➔ Ag2S. If 215.8 g of silver is mixed with 32.1 g of sulfide, how much silver sulfide (in grams) will be produced? Use equations to help you solve for the answer.
2. Iron oxide, known as hematite, is the main source of iron for the steel industry. It is created when iron and oxygen combine in a thermal decomposition reaction. It can be described using the equation 4Fe + 3O2 ➔ 2Fe2O3. If 19.2 g of O2 reacts with iron to form 63.84 g of iron oxide, how much iron in grams was used in the reaction? Use equations to help you solve for the answer.
3. Acetylene gas (C2H2) is used in welding torches. When it reacts with oxygen, it produces carbon dioxide (CO2) and steam (H2O). The reaction can be described by the equation:
2C2H2 + 5O2 ➔ 4CO2 + 2H2O. How much mass of C2H2 is needed to react with 68.1 g of O2 to produce 75.0 g of CO2 and 15.35 g of steam?
4. In the combustion reaction 2C2H6 + 7O2 ➔ 4CO2 + 6H2O, ethane gas reacts with oxygen to produce carbon dioxide and steam. If 18.6 g of C2H6 reacts with 69.2 g of O2 to produce 54.4 g of CO2, how much steam does it produce?
