Definition: Given a scientific passage and an answer, generate a question for the given answer.
Input: Passage: Like equations in math, equations in chemistry must balance. There must be the same number of each type of atom in the products as there is in the reactants. In equation 1, count the number of hydrogen and oxygen atoms on each side of the arrow. There are two hydrogen atoms in both reactants and products. There are two oxygen atoms in the reactants but only one in the product. Therefore, equation 1 is not balanced. Answer: reactants
Output:
What do you call the atomic "ingredients" that go into a chemical reaction?
