Calculate the amount of heat lost by the object(s) after being transferred from cup 1 to cup 2. Remember that a decrease in temperature is a negative change. Use the data recorded in parts A and C and the formula for heat transfer, Q = mCΔT.

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l

gas and precipitate r the correct answers
