find out the ΔH0rxn for the given reaction as C3H4(g) + 2 H2(g) → C3H8(g)
given information: C3H4(g) + 4 O2(g) → 3 CO2(g) + 2 H2O(l) ΔH0rxn = -1937 kJ/mol rxn , 2 H2(g) + O2(g)→ 2 H2O(l) ΔH0rxn = -571.6 kJ/mol rxn , C3H8(g) + 5 O2(g) → 3 CO2(g) + 4 H2O(l) ΔH0rxn = -2220 kJ/mol rxn
A 170.0 g sample of metal at 79.00*C is added to 170.0 g of H2O(l) at 14.00*C in an insulated container. The temperature rises to 16.19*C. Neglecting the heat capacity of the container, what is the specific heat of the metal

The analysis was completed by titrating the excess acid with 11.37 mL of 0.1080 M NaOH. How many of these tablets represent a proper dose for patients whose weight is 100 lb (assume that 1 pound, lb, is 0.45 kg).
Carbonyl fluoride, COF2, is an important intermediate used in the production of fluorine-containing compounds. For instance, it is used to make the refrigerant carbon tetrafluoride, CF4 via the reaction
what is the formula for calcium oxalate dihydrate when 100 degree Celsius heat is added?
how much product could form assuming no loss of grignard reagent to side reactions and addition of excess benzophenone.
What is the pH of the rainwater assuming all the sulfuric acid is in the liquid water droplet? Hint: The "per m3" means per m3 of air for both [H2SO4] and the cloud liquid water.
What is the expected freezing point of a 0.50 m solution of Li2SO4 in water? Kf for water is 1.86°C/m.
what is the likely magnitude of the equilibrium constant K? Hydrogen is used as a rocket fuel because it is very light and reacts explosively and completely with oxygen. For the combustion reaction
