1. (1 point) The [H+] of coffee is about 1 x 10. Its pH is 2. (1 point) The [OH-] of baking soda is about 1 x 10. Its pH is 9. The [H+] is 3. (4 points) Balance these equations by putting the number coefficients to the left of each product or reactant. If no number is needed (coefficient = 1), then leave that space blank. Al + O2 → Al2O3 а. NażCO3 + HCI → NaCl + CO2 + H20 C3H8 + O2 → CO2 + H2O с. d. CSH12 + O2 → CO2 + H2O 4.
