What is balanced chemical reaction Class 9?

Chemical change is brought about by addition, decomposition, exchange of atoms or molecules and the process by which chemical change occurs is called chemical reaction. If the total number of atoms in the reactants and products are same then the chemical reaction is said to be balancedchemical equation.

What are the 5 steps to balancing an equation?

How to Balance a Chemical Equation

1. Step 1: The Unbalanced Chemical Equation.
2. Step 2: Make a List.
3. Step 3: Identifying the Atoms in Each Element.
4. Step 4: Multiplying the Number of Atoms.
5. Step 5: Placing Coefficients in Front of Molecules.
6. Step 6: Check Equation.
7. Step 7: Balanced Chemical Equation.

What are the 5 rules for balancing equations?

To balance equations on your own, follow these simple rules:

• Check that all the formulae in the equation are correct.
• Deal with only one element at a time.
• Balancing is adding BIG numbers. You cannot change any of the small numbers in a chemical formula.
• Check each element again and repeat step 3 again if needed.

What are some examples of balance?

An example of balance is being able to walk on a tight rope. An example of balance is when a person divides his time evenly between work, family, and personal pleasure. An example of balance is a person who doesn’t get upset very often and doesn’t let the little things bother them.

What are the four steps to balancing a chemical equation?

1. Step 1: Make a Table. In a chemical equation there are subscripts and coefficients.
2. Step 2: Determining and Balancing the First Element. Pick an element that appears in one molecule on the left side and in one molecule on the left.
3. Step 3: Balancing Hydrogen.
4. Step 4: Balancing Oxygen.

How do I know if an equation is balanced?

If each side of the equation has the same number of atoms of a given element, that element is balanced. If all elements are balanced, the equation is balanced.
