1) Calculate the ∆H value for the following unbalanced reactionusing equations 1 and 2.    C (s) + H2 O (g) → CO 2 (g) + H 2 (g)
Equation 1: C (s) + O 2(g) → CO2(g)                 ∆H= –304 kJ
Equation 2: H 2 (g) + O 2 (g) → H2 O (g) ∆H = –242 kJ
2) Given 0.150 L of nitrous oxide at 25 °C and 749 mmHgpressure, calculate the number of N 2 O molecules
3) If 45.5 mL of 0.150 M sodium sulfate solution reacts with50.0 mL of 0.175 M aqueous barium nitrate
4) What is absolute zero? How do gas particles behave at thistemperature? List any four ideal gas
5) What is the [OH - ] of a solution that has a [H O + ] of 5.0× 10 -2 M? Is this solution acidic, basic or neutral?
