Answer 2

It seems like you're asking for the chemical reactions between aluminum (Al) and hydrochloric acid (HCl) and between calcium (Ca) and hydrochloric acid (HCl). Here are the balanced chemical equations for these reactions:

1. Reaction between aluminum and hydrochloric acid: 2 Al + 6 HCl → 2 AlCl3 + 3 H2

In this reaction, aluminum reacts with hydrochloric acid to produce aluminum chloride (AlCl3) and hydrogen gas (H2).

2. Reaction between calcium and hydrochloric acid: Ca + 2 HCl → CaCl2 + H2

In this reaction, calcium reacts with hydrochloric acid to produce calcium chloride (CaCl2) and hydrogen gas (H2).

Keep in mind that these reactions occur in an aqueous environment (in the presence of water) and are typically conducted under controlled conditions due to the release of hydrogen gas, which can be flammable. Additionally, handling acids and reactive metals should be done with appropriate safety precautions.
