4.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 2.40 moles of C2H2 with 7.40 moles of O2?

If you add 10ml of hot water to 10ml of cold water and the change in tempature 8°c calculate how much energy is gained by the cold water

For each of the following types of reactions, write a general reaction formula in the symbolic form—for example, a + b → ab. single-displacement double-displacement synthesis decomposition
