You need to start giving some of your thoughts first and/or explain exactly what you don't understand about the problem. When I give complete answers it means you don't learn how to do these problems yourself; it also means I'm doing your homework for you. The purpose of this web site is to HELP you do your homework. This is the last freebie; start showing your work and your thoughts.
Mg(s) + 2HCl(aq) ==> MgCl2(aq) + H2(g) is a single replacement reaction.
3. Convert everything to ions.
Mg(s) + H^+(aq) + Cl^-(aq) ==> Mg^2+(aq) + 2Cl^-(aq) + H2(g)
4. Mg(s) + 2HOH(l) ==> Mg(OH)2(s) + H2(g)
1. The general reaction type is a single replacement or displacement reaction.
2. The chemical equation for the reaction between magnesium (Mg) and an acid solution can be written as:
Mg + 2HCl (aq) → MgCl2 (aq) + H2 (g)
In this equation, Mg reacts with hydrochloric acid (HCl) to form magnesium chloride (MgCl2) and hydrogen gas (H2). "(aq)" represents the aqueous state, meaning the substances are dissolved in water, and "(g)" represents the gaseous state.
3. The complete ionic equation for the reaction can be written by separating the substances into their individual ions, if they are present in an aqueous solution. In this case, we assume the acid is fully ionized in solution:
Mg(s) + 2H+(aq) + 2Cl-(aq) → Mg2+(aq) + 2Cl-(aq) + H2(g)
Only the magnesium (Mg) is in its solid state, while the hydrogen ions (H+) and chloride ions (Cl-) are in their aqueous state, and the magnesium ions (Mg2+) and chloride ions (Cl-) remain unchanged in the reaction.
4. Magnesium reacts with water to produce magnesium hydroxide (Mg(OH)2) and hydrogen gas (H2). The chemical equation for this reaction is:
Mg(s) + 2H2O(l) → Mg(OH)2(aq) + H2(g)
In this equation, Mg reacts with water (H2O) to form magnesium hydroxide (Mg(OH)2) and hydrogen gas (H2). "(l)" represents the liquid state, indicating that water is in its liquid form, and "(aq)" represents the aqueous state, indicating that magnesium hydroxide is dissolved in water.
