Hydrazine is used as a rocket fuel. when 1.5 g of hydrazine N2H4, was burned in a bomb calorimeter, temp increased from 23.57 degrees celcius to 28.84 degrees celcius. The heat capacity of the calorimeter was 5.510 kJ/degree celcius. Determine the enthalpy of combustion of hydrazine.
A nuclear reaction involves the hypothetical element X, which has an atomic number of 166, as a reactant. The 360X nuclide reacts with 5 neutrons yielding a nuclide of element Y along with, altogether, 2 beta particles, 5 neutrons, 3 alpha particl..
H2 and Cl2 combine to form HCl. In a gas phase equilibrium mixture of H2, Cl2, and HCl at 300 K, [HCl] = 0.0036 mol/L and [Cl2] = 0.00485 mol/L.
