What is a balanced 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. Here is one way to work out how to do this for the reaction between nitrogen and hydrogen. Step. Result.
What is the purpose of balancing an equation?
The reason for balancing equations in chemistry is to obtain the correct proportions of reagents and products for a given reaction. Since chemical reactions do not change the atoms themselves, a balanced equation tells you how much product to expect for a given set of reagents.
What are the 2 types of chemical equations?
The Common Types of Chemical ReactionsCombination.Decomposition.Single displacement.Double displacement.Combustion.Redox.
How do you balance an equation algebraically?
The strategy for balancing chemical equations algebraically is as follows:Write 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.
