CIO^1(aq) + Cro(2)^- (aq) ->Cl^- (aq) + CrO(4)^2- (aq) (Basic)e. Obr^- (aq) +HPO(3)^2- (aq) ->Br^- (aq) + PO(4)^3- (aq) (Basic)
The standard molar enthalpy of formation of ClF3 is -405 kJ. 1/2 Cl2(g) + 3/2 F2(g) → ClF3(g)
Compute the volume of CO 2 and water vapour produced and the volume of oxygen remaining, when 20.0 dm 3 of propane reacts with 120.0 dm 3 of oxygen. All gas volumes are measured at the same temperature and pressure.
A sample of nitrogen gas is contained in a piston with a freely moving cylinder. At0?C, the volume of the gas is 248 mL. To what temperature must the gas be heated to occupy a volume of 479mL.
Calculate the Î"S for a gas in a closed system that is an ideal monatomic gas initially at P= 5 atm, V=5L, and T = 310 K which expands to V= 10 L and its temperature is increased to 390 K
Determine the concentration of the sulphuric acid (H2SO4) solution If It takes 58 mL of 0.124 M potassium hydroxide(KOH) to neutralize 41.5 mL of sulphuric acid( H2SO4) solution.? Express your answers in units of moles/liter
Four (4.00) moles of a perfect gas at 250.0 K and 1.50 bar pressure undergo a reversible isothermal compression until the pressure becomes 3.00 bar.
Determine the partial pressure and total pressure of the gases and Find the partial pressure of carbon dioxide in a gas mixture
