A method of converting one unit of measurement to another, like liters to milliliters.
The equation is:4Al+3O2----2Al2O3
Sugar increases the viscosity of water
hope that helps
It represents the number of moles required of that molecule to balance the chemical equation, which means to have the reaction chemically happen and goes to completion.
For example:
CH4 + O2 --> H2O + CO2 that is not balanced
with the coefficients located
CH4 + 2O2 --> 2H2O + CO2 now with the coefficients the number of oxygen and hydrogen on each side are equal
