6) The number of atoms of each element on each side of an equation must match.
True
False


7) A chemical equation uses formulas and symbols to show what happens during a chemical reaction.
True
False


8) Explain the procedure for balancing an equation

Answer 1

The answer is a 2 is b

Answer 2

1. Diatomic
2. Products
3. Reactants
4. Coefficient
5. Subscript
6. True
7. False
8. First you must write the reactants. Ensure the valencies of the reactants are correct. Draw an arrow. Write the products. Ensure the valencies of the products are correct and apply subscripts as necessary. Balance the equation by ensuring both sides have equal amounts of each elements - use only coefficients to complete this NOT subscripts.
