what must be balanced on the left side of an equation with the atoms on the right side of the equation?\nnumber of atoms of each element\ntotal number of compounds\nfree electrons\ntotal number of molecules
Answer
# Brief Explanations:
In a chemical equation, according to the law of conservation of mass, the number of atoms of each element on the left side (reactants) must be equal to the number of atoms of each element on the right side (products). The total number of compounds, free electrons, or total number of molecules do not need to be balanced in the same way as atoms of each element. For example, in the equation \(2H_2 + O_2\rightarrow 2H_2O\), the number of \(H\) atoms (4 on each side) and \(O\) atoms (2 on each side) are balanced.
# Answer:
number of atoms of each element
