How do you write a balanced chemical equation?
Identify the reactants and the products in the reaction and write their chemical formulae. Write the equation by putting the reactants on the left of the arrow and the products on the right. Count the number of atoms of each element in the reactants and the number of atoms of each element in the products.
How do you balance a symbol equation?
A balanced symbol equation has the same number of atoms of each element on both sides of the arrow. To balance an equation, add numbers to the left of one or more formulae.
What are the 5 types of chemical reactions examples?

How do you balance an equation using algebraic equations?
Algebraic method for balancing chemical equationsWrite a different letter coefficient in front of each compound in the equation.Write algebraic expressions or rules for each element that equate its atoms on the LHS and RHS.
Why do we balance chemical equations?
An equation is balanced when the same number of each element is represented on the reactant and product sides. Equations must be balanced to accurately reflect the law of conservation of matter.
