How do I balance equations in chemistry?
To balance a chemical equation, first write out your given formula with the reactants on the left of the arrow and the products on the right. For example, your equation should look something like “H2 + O2 → H2O.” Count the number of atoms in each element on each side of the equation and list them under that side.
How do you balance a Class 7 chemical equation?
Steps involved in balancing of chemical equation: Selecting the elements that occur for the least number of times in the equation. Balance atoms of each element on both sides of the reaction. Always leave hydrogen and oxygen for last to balance. Balance the hydrogen atoms lastly followed by balancing of oxygen atoms.
What are the steps in balancing chemical equations?
