What is true about balanced equations?
The amount on one side of the '=' must balance the amount on the other.
What is the purpose of writing a word equation in chemistry?
It is one way of representing a chemical reaction: it tells you what reacts and what is produced. Word equations are an efficient way to describe chemical changes, to help chemists recognize patterns, and to predict the products of a chemical reaction.
Which of the following is not one of the four provisions under EPCRA?
non-hazardous chemical inventories
When modeling word problems as mathematical equations what is a synonym for the division operation?
Not sure what you mean by "the following"; but one word that is often related to division is "per".
Which one of the following is a step for balancing chemical equations?
Determine how long the reaction will take. apex

What symbolic representation of a chemical reaction?
There are several things that may symbolize a chemical reaction. One of the main symbols is a chemical equation which will represent the entities in the reaction. .
What is true about balanced equations?
The amount on one side of the '=' must balance the amount on the other.
What do you mean by balanced chemical equation?
A balanced chemical equation is one where the number of the same atoms on both sides are equal. A balanced chemial equation is important because during a chemical reaction, there is rearrangement of atoms only and no new atoms are added. To understand the concept of a balanced chemical equation, first consider an unbalanced chemical equation between magnesium and oxygen to form magnesium oxide. Unbalanced chemical equation: Mg(s) + O2(g) --> MgO(s) Initially, this equation is unbalanced because if we count the number of the oxygen atoms on both sides, the number are unequal. There are two oxygen atoms on the left side but only one on the right side. A balanced chemical equation is one where the number of all of the same atoms on both side are equal. We can balance chemical equations by adding numbers to the coefficient of the chemicals that are involved in the reaction. Balanced chemical equation: 2Mg(s) + O2(g) --> 2MgO(s) This equation is now balanced because if we count the number of the same atoms on both side, they are equal. There are two magnesium atoms and two oxygen atoms on both sides of the equation.
Which one of the following equations represents the y- axis?
X = 0

What characteristics do balanced equations have?
They simply have the same numbers of atoms each element on one side of the equation as the other side.
What does a balanced chemical equation prove?
One or more products containing the same quantity of atoms as the reactants had
