The speed of light in a vacuum is 2.998 × 10^8 m/s. What is its speed in km/hr?

What volume is occupied by 19.6 g of methane, CH4, at 27 °C and 1.59 atm?

Given: 2 C2H2(g) + 5 O2(g) → 4 CO2(g) + 2 H2O(l), ΔH = −2600 kJ; C(s) + O2(g) → CO2(g), ΔH = −394 kJ; 2 H2(g) + O2(g) → 2 H2O(l), ΔH = −572 kJ. Using Hess’s Law, calculate ΔH for: 2 C(s) + H2(g) → C2H2(g).
