  1. In the following chemical equation what are the reactants and what are the products? CH8 + 3O2 CO2 + 4H2O

  2. CH8 + 3O2 CO2 + 4H2O Reactants Products

  3. In the chemical formula, AlCl3, what is the number 3 and what does it tell you?

  4. The three is a subscript. It tells you that there are three chlorine (Cl) atoms in the compound AlCl3

  5. How many aluminum (Al) atoms are in the compound, AlCl3?

  6. There is not a subscript after Al in the formula AlCl3, therefore we assume that there is only one Al atom in the compound.

  7. What uses symbols and formulas to show a chemical reaction?

  8. A chemical equation.

  9. What happens to energy in during an endothermic reaction? Does a substance feel hot or cold during an endothermic reaction?

  10. Energy is absorbed A substance feels cold during an endothermic reaction

  11. What happens to energy in during an exothermic reaction? Does a substance feel hot or cold during an exothermic reaction?

  12. Energy is released A substance feels hot during an exothermic reaction

  13. How many different types of atoms are there in KNO3? What are they?

  14. There are three different types of atoms are there in KNO3. They are potassium (K), nitrogen (N), and oxygen (O).

  15. In the formula, 4H2O, which number is the coefficient and what does it tell you?

  16. In the formula, 4H2O, the four is the coefficient. It tell you that there are four molecules of H2O (water).

  17. In the chemical formula, NH4Cl, how many atoms are there?

  18. There 6 atoms in NH4Cl. 1 + 4 + 1 = 6 atoms total

  19. In the chemical equation, 2H2O2 2H2O + O2, how many atoms are in the chemical equation?

  20. In the chemical equation, 2H2O2 2H2O + O2, there are 8 atoms total 4 + 4 = 8
