6. Hydrogen and oxygen combine to form water. What is the theoretical yield of water, if I have 16 moles of hydrogen gas and 10 moles of oxygen gas? What is the limiting
reactant? In an experiment, I collect 250 grams of water. What is my percent yield?

chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. these processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. understanding chemical changes is a major part of the science of chemistry.
