2. Which of the following is a characteristic product of a combustion reaction?
A single, more complex compound
Two new ionic compounds
Carbon dioxide and water
A metal and a new ionic compound
3. In a single displacement reaction, a more reactive displaces a less reactive element from a compound.
4. When an acid reacts with a base, the products are usually a and .
5. Predict the products and balance the following synthesis reaction:
Mg(s) + O₂(g) →
6. Predict the products and balance the following decomposition reaction:
KClO₃(s) →
7. Predict the products and balance the following single displacement reaction:
Zn(s) + HCl(aq) →
