Question: Answer the following question given this paragraph: In a chemical reaction, the quantity of each element does not change; there is the same amount of each element in the products as there was in the reactants. This is because matter is always conserved. The conservation of matter is reflected in a reaction's chemical equation. The same number of atoms of each element appears on each side of the arrow. For example, in the chemical equation above, there are four hydrogen atoms on each side of the arrow. Can you find all four of them on each side of this equation?. Q: Matter is always conserved in what type of reaction? Choices: - developed reaction - Quick reaction - toxic reaction - chemical reaction A:
Answer:
chemical reaction
