Balance Equations Hangers

Front

What is a balanced equation?

Back

A balanced equation is an equation in which the number of atoms for each element is the same on both sides of the equation, ensuring that mass is conserved.

Front

What does it mean to isolate a variable in an equation?

Back

Isolating a variable means rearranging the equation so that the variable is on one side by itself, making it easier to solve for that variable.

Front

What is the principle of maintaining balance in equations?

Back

The principle states that whatever operation is performed on one side of the equation must also be performed on the other side to maintain equality.
