a CO(NH2)2 + b H2O = c CO2 + d NH3 Step 2: Create a System of Equations Create an equation for each element (C, O, N, H) where each term represents the number of atoms of the element in each reactant or product. C: 1a + 0b = 1c + 0d O: 1a + 1b = 2c + 0d ...
H2O = NH3 + CO2 + H2O must have the same number of atoms on each side of the equation. When using the inspection method (also known as the trial-and-error method), this principle is used to balance one element at a time until both sides are equal and the chemical equa...
