In chemistry, a balanced chemical equation is a representation of a chemical reaction where the number of atoms for each element is the same on both the reactant and product sides. This balance is crucial in understanding the stoichiometry of a reaction, which is the quantitative relationship between reactants and products. In this article, we will explore the concept of balanced chemical equations and examine the given choices to determine which one represents a balanced chemical equation.

What is a Balanced Chemical Equation?

A balanced chemical equation is a representation of a chemical reaction where the number of atoms for each element is the same on both the reactant and product sides. This balance is achieved by adjusting the coefficients of the reactants and products. The coefficients are numbers that are placed in front of the formulas of the reactants and products to indicate the number of molecules or moles of each substance that participate in the reaction.

Importance of Balanced Chemical Equations

Balanced chemical equations are essential in chemistry because they provide a clear representation of the reactants and products involved in a chemical reaction. This balance is crucial in understanding the stoichiometry of a reaction, which is the quantitative relationship between reactants and products. A balanced chemical equation also helps to:

  • Predict the products of a reaction: By analyzing the reactants and products in a balanced chemical equation, chemists can predict the products of a reaction.
  • Determine the limiting reactant: A balanced chemical equation helps to identify the limiting reactant, which is the reactant that is consumed first in a reaction.
  • Calculate the amount of product formed: By using the coefficients in a balanced chemical equation, chemists can calculate the amount of product formed in a reaction.

Analyzing the Given Choices

Now that we have a clear understanding of balanced chemical equations, let's analyze the given choices to determine which one represents a balanced chemical equation.

Choice A: Ca3(PO4)2+6SiO2β†’P4O10+3CaSiO3Ca_3(PO_4)_2 + 6SiO_2 \rightarrow P_4O_{10} + 3CaSiO_3

In this choice, the reactants are Ca3(PO4)2Ca_3(PO_4)_2 and 6SiO26SiO_2, and the products are P4O10P_4O_{10} and 3CaSiO33CaSiO_3. To determine if this equation is balanced, we need to count the number of atoms of each element on both the reactant and product sides.

Element Reactant Side Product Side

Element Reactant Side Product Side
Ca 6 6
P 4 4
O 16 10
Si 6 6

As we can see, the number of atoms of each element is not the same on both the reactant and product sides. Therefore, this equation is not balanced.

Choice C: Ca3(PO4)2+3SiO2β†’P2O5+3CaSiO3Ca_3(PO_4)_2 + 3SiO_2 \rightarrow P_2O_5 + 3CaSiO_3

In this choice, the reactants are Ca3(PO4)2Ca_3(PO_4)_2 and 3SiO23SiO_2, and the products are P2O5P_2O_5 and 3CaSiO33CaSiO_3. To determine if this equation is balanced, we need to count the number of atoms of each element on both the reactant and product sides.

Element Reactant Side Product Side
