How is the law of conservation of mass used to balance a chemical equation?
In a chemical equation, the products formed have the same atoms as the original reactants; however, the atoms may be rearranged. The law of conservation of mass states that the coefficients of atoms in the products must be equal to the coefficients of atoms in the reactants. Therefore, coefficients are used to balance the equation.
In a chemical equation, the products formed have the same atoms as the original reactants; however, the atoms may be rearranged. The law of conservation of mass states that the subscripts of atoms in the products must be equal to the subscripts of atoms in the reactants. Therefore, subscripts are used to balance the equation.

answer: In a chemical equation, the products formed have the same atoms as the original reactants; however, the atoms may be rearranged. The law of conservation of mass states that the number of atoms of each element in the products must be equal to the number of atoms of the same element in the reactants. Therefore, coefficients are used to balance the equation.
In a chemical equation, the law of conservation of mass is used to balance the equation by ensuring that the number of atoms of each element is the same on both sides of the equation. Coefficients are used to accomplish this. By adjusting the coefficients, you can make sure that the number of atoms of each element in the reactants equals the number of atoms of that element in the products. This allows you to uphold the principle that mass is conserved in a chemical reaction.
In a chemical equation, the law of conservation of mass is used to ensure that the total mass of the reactants is equal to the total mass of the products. This law states that matter cannot be created or destroyed in a chemical reaction; it can only be rearranged.
To balance a chemical equation, you need to ensure that the number of atoms of each element on the left side (reactants) is equal to the number of atoms of the same element on the right side (products). This is achieved by adjusting the coefficients (numbers in front of the chemical formulas) of the reactants and products.
If we are given an unbalanced equation such as:
2H2 + O2 -> H2O
We can start by counting the number of atoms of each element on both sides of the equation. In this case, there are 4 hydrogen (H) atoms and 2 oxygen (O) atoms on the left side, whereas there are only 2 hydrogen atoms and 1 oxygen atom on the right side.
To balance the hydrogen atoms, we can put a coefficient of 2 in front of the water molecule:
2H2 + O2 -> 2H2O
Now, there are 4 hydrogen atoms on both sides of the equation. However, this has also doubled the number of oxygen atoms on the right side. To balance the oxygen atoms, we can place a coefficient of 2 in front of the oxygen molecule:
2H2 + 2O2 -> 2H2O
Now, the equation is balanced, as there are 4 hydrogen atoms and 4 oxygen atoms on both sides.
In summary, the law of conservation of mass is used to balance a chemical equation by adjusting the coefficients of the reactants and products to ensure that the number of atoms of each element is the same on both sides of the equation.
