How do you 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.
What is meant by balance equation?
A balanced equation is an equation for a chemical reaction in which the number of atoms for each element in the reaction and the total charge is the same for both the reactants and the products. In other words, the mass and the charge are balanced on both sides of the reaction.

What is the coefficient of an equation if there is no coefficient in front of an element?
Now the number of atoms in each element is the same on both sides of the equation, so the equation is balanced. Remember that if there's no coefficient in front of an element, it's assumed that the coefficient is 1. To learn how to balance chemical equations algebraically, scroll down!
How to find the number of atoms in an equation?
Write down the number of atoms per element . Do this for each side of the equation. Look at the subscripts next to each atom to find the number of atoms in the equation. When writing it out, it's a good idea to connect it back to the original equation, noting how each element appears.
Why is the equation not balanced?
Since the number of atoms in each element isn't identical on both sides, the equation is not balanced. To balance the equation, you'll need to add coefficients to change the number of atoms on one side to match the other.
Why do you add a 4 as the coefficient?
On the right side, you now added a 4 as the coefficient because the subscript showed that you already had 2 hydrogen atoms. When you multiply the coefficient 4 times by the subscript 2, you end up with 8. Balance the oxygen atoms. Remember to account for the coefficients that you've used to balance out the other atoms.
How many oxygen atoms are in water?
Because you've added coefficients to the molecules on the right side of the equation, the number of oxygen atoms has changed. You now have 4 oxygen atoms in the water molecules and 6 oxygen atoms in the carbon dioxide molecules.
What is the law of conservation of mass?
The law of conservation of mass states that no atoms can be created or destroyed in a chemical reaction, so the number of atoms that are present in the reactants has to balance the number of atoms that are present in the products. Follow this guide to learn how to balance chemical equations differently. Steps.
How to balance a chemical equation?
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.
Why is it important to balance chemical equations?
This is important because a chemical equation must obey the law of conservation of mass and the law of constant proportions , i.e. the same number of atoms of each element must exist on ...
What is the chemical equation?
A chemical equation is a symbolic representation of a chemical reaction in which the reactants and products are denoted by their respective chemical formulae. An example of a chemical equation is 2H2 + O2 → 2H2O which describes the reaction between hydrogen and oxygen to form water. The reactant side is the part of the chemical equation to ...
What is the equation for aluminium?
First, the aluminium atoms are balanced. The equation becomes 2Al + O2 → Al2O3
What is the stoichiometric coefficient for hydrogen?
Therefore, the stoichiometric coefficient that must be assigned to hydrogen is 3. Chemical Equation: N 2 + 3H 2 → 2NH 3. Reactant Side.
What are algebraic variables assigned to?
Now, algebraic variables are assigned to each species (as stoichiometric coefficients) in the unbalanced chemical equation. In this example, the equation can be written as follows.
How to find the total number of atoms in a species?
The total number of atoms of an element present in a species (in a balanced chemical equation) is equal to the product of the stoichiometric coefficient and the number of atoms of the element in one molecule of the species. For example, the total number of oxygen atoms in the reacting species ‘2O 2 ’ is 4. While balancing chemical equations, ...
Why is it important to note that these equations must be solved in a manner that each variable is a positive?
It is important to note that these equations must be solved in a manner that each variable is a positive integer. If fractional values are obtained , the lowest common denominator between all the variables must be multiplied with each variable. This is necessary because the variables hold the values of the stoichiometric coefficients, which must be a positive integer.
