![]() ![]() A question asking "how much" of another substance is needed or formed in the reaction.A stated amount of one component of the reaction.Such calculations are calledĪ stoichiometric problem can be stated in many ways, but it always contains the following information: Given the number of moles of one component used or produced in a reaction, the number of moles or grams of any other component used or produced can be calculated. These quantitative relationshipsĪny balanced equation gives the ratio between moles of reactants and moles of products. The reaction wouldįorm molecules (5 moles) of carbon dioxide and [6(6.02 X 10 23)] molecules (8 moles) of oxygen are needed. If 6.02 x 10 23 molecules (1 mole) of pentane are burned, [8(6.02 Of carbon dioxide and 6n molecules of water would be formed. ![]() Whatever number (n) of molecules of pentane were used in the reaction, 5n molecules X 15) or 120 molecules of oxygen would be needed for complete reaction (5 xġ5) molecules of carbon dioxide and (6 x 15) molecules of water would be formed. Of carbon dioxide and 6 molecules of water. That 1 molecule of pentane reacts with 8 molecules of oxygen to form 5 molecules In quantitative terms, the equation states In qualitative terms, this equation shows that pentane reacts with oxygen The balanced equation for the combustion of pentane is: Pentane, C 5H 12, burns in oxygen to form carbon dioxide and water. ![]() Let us see what this statement means in terms of a particular reaction. It relates amounts of reactants to amounts of products. A balanced equation is a quantitative statement of a reaction. ![]()
