1) Calculate the ∆H value for the following unbalanced reaction using equations 1 and 2. C (s) + H 2 O (g) → CO 2 (g) + H 2 (g)
Equation 1: C (s) + O 2(g) → CO 2 (g) ∆H = –304 kJ
Equation 2: H 2 (g) + O 2 (g) → H 2 O (g) ∆H = –242 kJ
2) Given 0.150 L of nitrous oxide at 25 °C and 749 mmHg pressure, calculate the number of N 2 O molecules
3) If 45.5 mL of 0.150 M sodium sulfate solution reacts with 50.0 mL of 0.175 M aqueous barium nitrate
4) What is absolute zero? How do gas particles behave at this temperature? 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?
3) i think the Question is incomplete.
4) Absolute temperature is the lowest possible thermodynamic temperature. Absolute zero temperature is 0K or -273.150 c.
At this temperature, the volume of ideal gas approaches zero. The gas will be no longer gas, but solid.
Examples of ideal gases are :
ideal gas is an ideal concept. Gases like hydrogen, nitrogen, oxygen and CO2 can be considered as ideal gas under certain conditions.
