The coefficient in a balanced equation is an idea; the concept of telling the chemist that if the atoms, molecules and compounds are balanced, there are balanced amounts of the atoms, molecules and compounds on the other side in the product. b. There are two choose the mathematics that appear in chemical equations. Because one molecule of n-heptane contains 7 carbon atoms, we need 7 CO2 molecules, each of which contains 1 carbon atom, on the right side: \[\ce{C7H16 (l) + O2 (g) } \underline{7} \ce{CO2 (g) + H2O (g) } \nonumber \]. The equation is now weighed, or there are negative fractional coefficients: go is 7 carbon atomics, 16 hydrogen atoms, and 22 oxygen atoms on each side. and so it looks like the aluminums are balanced, Similarly, you can calculate it manually or using chemical equation product calculator. It's describing a reaction. The classical approach uses oxidation numbers and many chemists how do you balance equation with just whole number?
