Which of the following answer choices occurs in a double replacement reaction? The reactants are two elements The reactants are two ionic compounds The products are always molecular One reactant is always oxygen

The starting materials in a chemical reaction are called your "initial products". True False If the number of each type of atom on one side of the arrow differs from the number on the other side, the equation is still considered balance. True False Stoichiometry is the qualitative study of reactants and products in a chemical reaction. True False

Consider the following unbalanced equation. How many molecules of hydrogen will be required to produce 1.60 mol of water?H2 + O2  H2O

Question Completion Status: QUESTION 2 Balancing refers to the number of substances put INTO a reaction has to equal the number of substance PRODUCED by the reaction. This means there must be an understanding of HOW MANY of something is put into a reaction. Match the following description with the HOW MANY X of each substance. Answers may be used once, more than once, or not at all.

Consider a reaction in which two reactants make one product (for example, consider the unbalanced A + B → C). You know the following: 2.0 mol A (with an excess of B) can make a maximum of 4.0 mol C 3.0 mol B (with an excess of A) can make a maximum of 8.0 mol C If you react 2.0 mol A and 3.0 mol B, what is the maximum amount of C that can be produced?
