When the coefficients of the formulas in a chemical equation have been adjusted to satisfy the law of of , the equation is said to be balanced.

When the coefficients of the formulas in a chemical equation have been adjusted to satisfy the law of conservation of mass, the equation is said to be balanced. This means that the number of atoms for each element in the reactants side of the equation matches the number of atoms for that element on the products side.

Here are the steps to balance a chemical equation:

1. Write down the unbalanced equation: This is the initial equation that you are given, which does not yet obey the law of conservation of mass.

2. Count the atoms of each element in the reactants and the products: This will give you an idea of how many atoms of each element are present on both sides of the equation.

3. Balance the elements one at a time: Start with an element that appears in only one compound on each side of the equation. Change the coefficients (the numbers in front of the compound or molecule) to balance the atoms of that element.

4. Check your work: Count the atoms of each element again to make sure that both sides of the equation are balanced. If they are not, go back to step 3 and try again.

5. Repeat the process: Continue this process until all elements are balanced.

6. Check your work again: Once you think the equation is balanced, check one more time to make sure that you didn't miss anything.

Remember, you can only change the coefficients in front of compounds to balance a chemical equation, you cannot change the subscripts inside a chemical formula.
