Understanding the Chemical Equation

Chemical equations are a fundamental concept in chemistry that describe the interaction between reactants to form products. In this article, we will focus on choosing the products that complete the reaction, given a chemical equation that may not be balanced. The chemical equation provided is:

HC2H3O2+Ca(OH)2→?{ \text{HC}_2\text{H}_3\text{O}_2 + \text{Ca(OH)}_2 \rightarrow ? }

Identifying the Reactants

The first step in solving this problem is to identify the reactants involved in the chemical equation. In this case, the reactants are:

  • HC2H3O2: Acetic acid, a weak organic acid
  • Ca(OH)2: Calcium hydroxide, a strong base

Balancing the Chemical Equation

Before we can choose the products that complete the reaction, we need to balance the chemical equation. Balancing a chemical equation involves adding coefficients to the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation.

Let's start by balancing the calcium (Ca) atoms. Since there is one calcium atom on the reactant side, we need to add a coefficient of 2 in front of Ca(OH)2 to balance the calcium atoms.

HC2H3O2+2Ca(OH)2→?{ \text{HC}_2\text{H}_3\text{O}_2 + 2\text{Ca(OH)}_2 \rightarrow ? }

Next, we need to balance the hydrogen (H) atoms. There are 2 hydrogen atoms in HC2H3O2 and 4 hydrogen atoms in 2Ca(OH)2. To balance the hydrogen atoms, we need to add a coefficient of 2 in front of HC2H3O2.

2HC2H3O2+2Ca(OH)2→?{ 2\text{HC}_2\text{H}_3\text{O}_2 + 2\text{Ca(OH)}_2 \rightarrow ? }

Now, let's balance the oxygen (O) atoms. There are 2 oxygen atoms in HC2H3O2 and 4 oxygen atoms in 2Ca(OH)2. To balance the oxygen atoms, we need to add a coefficient of 2 in front of HC2H3O2.

2HC2H3O2+2Ca(OH)2→?{ 2\text{HC}_2\text{H}_3\text{O}_2 + 2\text{Ca(OH)}_2 \rightarrow ? }

Finally, let's balance the carbon (C) atoms. There is 1 carbon atom in HC2H3O2. To balance the carbon atoms, we need to add a coefficient of 2 in front of HC2H3O2.

2HC2H3O2+2Ca(OH)2→?{ 2\text{HC}_2\text{H}_3\text{O}_2 + 2\text{Ca(OH)}_2 \rightarrow ? }

Choosing the Products

Now that we have balanced the chemical equation, we can choose the products that complete the reaction. The products are:

  • Ca(C2H3O2)2: Calcium acetate, a salt formed by the reaction of calcium hydroxide and acetic acid
  • H2O: Water, a byproduct of the reaction

The balanced chemical equation is:

2HC2H3O2+2Ca(OH)2→Ca(C2H3O2)2+2H2O{ 2\text{HC}_2\text{H}_3\text{O}_2 + 2\text{Ca(OH)}_2 \rightarrow \text{Ca(C}_2\text{H}_3\text{O}_2)_2 + 2\text{H}_2\text{O} }

Conclusion

In conclusion, the products that complete the reaction are:

Ca(C2H3O2)2+2H2O{ \text{Ca(C}_2\text{H}_3\text{O}_2)_2 + 2\text{H}_2\text{O} }

This reaction involves the reaction of acetic acid and calcium hydroxide to form calcium acetate and water. The balanced chemical equation is:

2HC2H3O2+2Ca(OH)2→Ca(C2H3O2)2+2H2O{ 2\text{HC}_2\text{H}_3\text{O}_2 + 2\text{Ca(OH)}_2 \rightarrow \text{Ca(C}_2\text{H}_3\text{O}_2)_2 + 2\text{H}_2\text{O} }
