Given:
At 25 degrees Celcius:
amount of generic salt AB3 = 0.0260 moles
Volume of solvent = 1.0 L water
Set up a balanced chemical equation:
AB3 =========> A3+ + 3B-
0.0260M 0.0260 0.078
Ksp = [A][B]^3
Ksp = 1.23 x 10^-5<span />
Answer:
719.83°C
Explanation:
The heat that the sample of Zinc gives is equal to the heat that water is absorbing. That is:
C(Zn) * m(Zn) * ΔT(Zn) = C(H2O) * m(H2O) * ΔT(H2O)
<em>Where:</em>
<em>C is specific heat (Zn: 0.390J/g°C; H2O: 4.184J/g°C)</em>
<em>m is mass (Zn: 2.50g; H2O: 65.0g)</em>
<em>ΔT (Zn: ?; H2O: (22.5°C - 20.0°C = 2.50°C)</em>
<em />
Replacing:
0.390J/g°C * 2.50g * ΔT(Zn) = 4.184J/g°C * 65.0g * 2.50
ΔT(Zn) = 697.33°C
As final temperature of Zn is 22.50°C, initial temperature is:
Initial temperature: 697.33°C + 22.50°C
719.83°C
