C.) new substances that are present at the end of a reaction.
D.) substances that were not used up in a reaction.

C.) new substances that are present at the end of a reaction.

Explanation:

In a chemical reaction, substances are combined to form other substances. The substances, in a chemical reaction, that are combined or used up are called REACTANTS while those substances that are synthesised newly at the end of the reaction are called PRODUCTS.

For example, in the chemical reaction between carbon dioxide and water in photosynthesis to form glucose and oxygen as follows:

6CO2 + 6H2O --> C6H12O6 + 602

CO2 and H2O are the REACTANTS because they are the combined substances.

C6H12O6 and 02 are the PRODUCTS because they are new substances present at the end of the reaction.

indium, and thallium have three electrons i think

it's c. elements are placed in rows based on how may valencies electrons have.
