A beaker of nitric acid is neutralized with calcium hydroxide. Write a balanced molecular equation and a net ionic equation for this reaction.
calculate the specific heat capacity of a sample liquid if this 100 g sample of an unknown liquid absorbs 2000 j of
If 8.60 g of NaHCO3(s) are combined with 32.2 mL of 0.800 M H2SO4, how many moles of CO2(g) would be produced if reaction occurred as completely as possible. Calculate the number of moles of both reactants first and then identify limiting reactant..
Identify the largest heat of combustion, small heat of combustion and highest boiling point for: heptane(i), 3-methylhexane(ii), nonane(iii)
when NaOH is added to this solution, a white precipitate forms. Using an equation, provide the identity of the white precipitate and explain its formation.
The purification of hydrogen gas is possible by diffusion through a thin palladium sheet. Calculate the number of kilograms of hydrogen that pass per hour (in kg/h) through a 4.7 mm thick sheet of palladium having an area of 0.25 m2 at 500°C.
The vapor pressure of dichloromethane,CH_2CL_2,at 0 degree C is 134mmHg. The normal boiling point of dichloromethane is 40 degree C. Calculate molar heat of vaporation.
Titrate 80ml of NH3 w/35ml of 0.30M HCl. Find pH and select an indicator beside bromocresol green that can be used.
Nitrogen and 20% of Oxygen, and that the pressure at sea level is 1.000 atmosphere, calculate the partial pressures of each gas and the total gas pressure in the middle of the stratosphere at 35.00km altitude, where T=240.0 K.
what will be the volume of the blimp at a height of 2300 m, where the temperature is 12°C?
Calculate the pH of a solution prepared by mixing 15.0mL of 0.10M NaOH and 30.0mL of 0.10M benzoic acid solution. (Benzoic acid is monoprotic; its dissociation constant is 6.5x10^-5.)
