Which of the following statements are true about chemical reactions?
Check all that apply.
A. Reactants are on the right when writing a chemical reaction.
B. Products are produced in a reaction.
C. Reactants are present at the end of a reaction.
D. Products are on the right when writing a chemical reaction.
To determine which of the statements are true about chemical reactions, we can look at the general format for writing chemical reactions. The most common way to represent a chemical reaction is using a chemical equation, which consists of reactants on the left side and products on the right side.
Statement A: "Reactants are on the right when writing a chemical reaction."
This statement is false. Reactants are typically on the left side of a chemical equation.
Statement B: "Products are produced in a reaction."
This statement is true. Products are formed as a result of a chemical reaction.
Statement C: "Reactants are present at the end of a reaction."
This statement is false. Reactants are consumed during a chemical reaction and are typically not present at the end of the reaction.
Statement D: "Products are on the right when writing a chemical reaction."
This statement is true. Products are usually written on the right side of a chemical equation.
In conclusion, the true statements about chemical reactions are:
- Statement B: Products are produced in a reaction.
- Statement D: Products are on the right when writing a chemical reaction.
Based on the information given, the correct statements about chemical reactions are:
B. Products are produced in a reaction.
D. Products are on the right when writing a chemical reaction.
A is not true.
B is true.
C MAY be true.
D is true.
