Answer 1

3HCl + Fe(OH)3 -----> FeCl3 + 3H2O
2HCl + CaCO3 ----> CaCl2 + H2O + CO2
2HCl + Li2O ----> 2LiCl + H2O

Answer 2

Reactivity of Hydrochloric Acid with Listed Substances

Hydrochloric acid (HCl) can react with various substances, resulting in different chemical reactions. Let's explore the possible reactions with the listed substances.

1. Hydroxide Iron(III) (Fe(OH)3): - Hydrochloric acid will react with hydroxide iron(III) to form a salt and water. - The balanced chemical equation for the reaction is: ``` Fe(OH)3 + 3HCl → FeCl3 + 3H2O ``` - This reaction is a classic acid-base neutralization reaction.

2. Phosphorus(V) Oxide (P2O5): - Hydrochloric acid will react with phosphorus(V) oxide to form phosphoric acid. - The balanced chemical equation for the reaction is: ``` P2O5 + 6HCl → 2H3PO4 + 3Cl2 ``` - This reaction is an example of an acid-base reaction where an oxide reacts with an acid to form a salt and water.

3. Calcium Carbonate (CaCO3): - Hydrochloric acid will react with calcium carbonate to form calcium chloride, carbon dioxide, and water. - The balanced chemical equation for the reaction is: ``` CaCO3 + 2HCl → CaCl2 + CO2 + H2O ``` - This reaction is a common demonstration of the reactivity of acids with carbonates, resulting in the release of carbon dioxide gas.

4. Lithium Oxide (Li2O): - Hydrochloric acid will react with lithium oxide to form lithium chloride and water. - The balanced chemical equation for the reaction is: ``` Li2O + 2HCl → 2LiCl + H2O ``` - This reaction is another example of an acid-base neutralization reaction.
