mg(oH)2(s)+2hcl(g)_Mgcl2(s)+2h2o(g)

I don't see a question. (I don't see a valid equation either.)

This reaction involves the reaction between solid magnesium hydroxide (Mg(OH)2) and gaseous hydrogen chloride (HCl) to form solid magnesium chloride (MgCl2) and gaseous water (H2O).

Step 1: Write the balanced chemical equation for the reaction.

The balanced chemical equation is:
Mg(OH)2(s) + 2HCl(g) -> MgCl2(s) + 2H2O(g)

This equation shows that one molecule of Mg(OH)2 reacts with two molecules of HCl to produce one molecule of MgCl2 and two molecules of H2O.

Step 2: Determine the stoichiometry of the reaction.

From the balanced chemical equation, we can determine the stoichiometry of the reaction. It tells us the mole ratio of the reactants and products.

According to the balanced equation, for each molecule of Mg(OH)2, we need two molecules of HCl to produce one molecule of MgCl2 and two molecules of H2O.

Step 3: Identify the reactants and products.

Reactants:
- Magnesium hydroxide (Mg(OH)2)
- Hydrogen chloride (HCl)

Products:
- Magnesium chloride (MgCl2)
- Water (H2O)

Step 4: Determine the amounts of reactants and products.

The given chemical equation does not provide specific amounts of reactants or products. In order to determine the amounts, additional information such as the mass or volume of the reactants is needed, or you may be given the number of moles.

Step 5: Balance the equation (if needed).

The given equation is already balanced, so no further balancing is required.

Remember to always double-check the coefficients of the balanced equation you use to ensure accuracy in stoichiometric calculations.

The given chemical equation describes a reaction between solid magnesium hydroxide (Mg(OH)2) and gaseous hydrochloric acid (HCl) that forms solid magnesium chloride (MgCl2) and gaseous water (H2O) as products.

To balance this equation, we need to ensure that the number of atoms of each element on both sides of the equation is equal. Let's go through the balancing process step by step.

1. Count the number of atoms on the reactant side:
- Mg: 1
- O: 2
- H: 4
- Cl: 2

2. Count the number of atoms on the product side:
- Mg: 1
- O: 2
- H: 4
- Cl: 2

The number of atoms is already balanced for magnesium (Mg), oxygen (O), hydrogen (H), and chlorine (Cl).

So, the balanced chemical equation is:
Mg(OH)2(s) + 2 HCl(g) → MgCl2(s) + 2 H2O(g)

This means that one molecule of solid magnesium hydroxide reacts with two molecules of gaseous hydrochloric acid to produce one molecule of solid magnesium chloride and two molecules of gaseous water.

Note: It's important to keep in mind that chemical equations should always be balanced to accurately represent the reactants and products involved in a chemical reaction.
