Final answer:
The student's question is about predicting products and writing balanced chemical equations for different types of chemical reactions, including single-replacement, decomposition, and acid-base neutralization reactions.
Step-by-step explanation:
The question involves predicting the products and writing the balanced chemical equations for a variety of chemical reactions, including single-replacement reactions, synthesis reactions, decomposition reactions, and acid-base neutralization reactions.
The question covers different types of chemical reactions that can occur between elements, compounds, and aqueous solutions. An example of a single-replacement reaction would be Mg + HCl yielding MgCl2 and H2, which is balanced as Mg(s) + 2HCl(aq) -> MgCl2(aq) + H2(g).
Acid-base neutralization reactions involve an acid reacting with a base, resulting in the formation of water and a salt. For example,
Mg(OH)2(s) + 2HClO4(aq) produces Mg(ClO4)2(aq) and H2O(l),
and the balanced equation is Mg(OH)2(s) + 2HClO4(aq) -> Mg(ClO4)2(aq) + 2H2O(l).
