Cad4U a local metal processing facility is at present violating its discharge permits for dissolved cadmium, Cd2+. The regulations are based on activity rather than concentration as well as so the savvy ore unethical chief chemist decided to alter..
A solution is made by combining 15.0mL of 16.5M acetic acid with 5.52g of sodium acetate and diluting to a volume of 1.50L
Write down the dissociation reaction. (2) Estimate pH of a solution containing 0.6 g of acetic acid in 1 L of water. Molecular weight of acetic acid is 60 g/mol.
earlier, lower-energy TS. Can model reaction coordinate as inverse parabolic potential well. What happens when we make X a better leaving group? Model by tilting entire plot forward. What happens when we make X a better leaving group?
The formula for caluculating a dilution of a solution is M1V1=M2V2, use this equation to calculate the volume of a 2.0 M solution of sodium carbonate required to make 100mL of a 0.25 M solution. A1) calculate the mass of calium chloride dihydrate
What mass of calcium nitrate would need to be added to 100.0 mL of 1.0 M ammonia (Kb = 1.8*10^-5) to precipitate calcium hydroxide (Ksp = 5.5 *10^-6 Assume no volume changes occur
What is the average mass of calcium in each sample? (Assume that the relative uncertainties in atomic mass are small compared the uncertainty of the total mass.)
