Sure! Here are the clear and concise answers to the questions provided: 1. The product in the equation Zn + CuSO4 is ZnSO4 + Cu. So, the correct choice is C. ZnSO4 and Cu. 2. The chemical equation is balanced by adding coefficients. Therefore, the correct choice is C. adding coefficients. 3. The statement that explains the chemical reaction process is: C. The law of conservation of mass applies. This law states that matter is neither created nor destroyed in a chemical reaction, supporting the conservation of mass. 4. During a chemical reaction, matter particles undergo rearrangement, not destruction. Therefore, the correct choice is B. Atoms are rearranged. These answers provide a clear understanding of the concepts related to the given questions. If you need further clarification or have more questions, feel free to ask!
