The solubility of slaked lime, Ca(OH)2, in water is 0.185 g/100 mL. What volume of 0.00300 M HCL is needed to neutralize 14.0 mL of saturated Ca(OH)2 solution
When doing the kinetic trial, Peyton mistakenly omitted the starch solution from the kinetic trials. How will this omission change the appearance of the resultant solution (from mixing solutions A&B)
The amount of boiling water required to raise the temperature of 25 kg of water in the bath to body temperature is 4.8 kg. In this process, the heat lost by the boiling water is equal to the heat gained by the room-temperature water.
What is the resulting temperature when 35 g of water at 75C is mixed with 15 g of water at 15C? (The specific heat of water is 4.184 J/g x C.)
Calculate the boiling point of a 2.97m aqueous solution of ethylene glycol, a nonvolatile nonelectrolyte.
Balance the following chemical reaction using the lowest integer coefficients, in acidic conditions I?(aq) + BrO3?(aq) ? HIO(aq) + Br?(aq)
Calculate the pH of a solution made by adding 42 g of sodium acetate, NaCH3COO, to 16 g of acetic acid, CH3COOH, and dissolving in water to make 300. mL of solution.
Calculate the molar mass of the unknown gas. (Remember that the faster the rate of effusion, the shorter the time required for effusion of 1.0 L; that is, rate and time are inversely proportional.)
Write the reaction between ferric chloride and lime slurry that results in precipitation of Fe(OH)3. For a dosage of 40 mg/l FeCl3: What is the required stoichiometric addition of lime expressed as CaO?
