C. The heat released when the aluminum is cooled from 70°C to 50°C is -180 J.

<h3>What is Specific heat capacity?</h3>

Specific heat capacity is the quantity of heat needed to raise the temperature per unit mass.

<h3>Heat released when the aluminum is cooled </h3>

The heat released when the aluminum is cooled from 70°C to 50°C is calculated as follows;

Q = mcΔθ

where;

m is mass of the aluminum
c is specific heat capacity
Δθ is change in temperature

Q = (10)(0.9)(50 - 70)

Q = -180 J

Thus, the heat released when the aluminum is cooled from 70°C to 50°C is -180 J.

Answer:

Follows are the solution to the given question:

Explanation:

Following are the balanced redox equation:

$Cr_2O_7^{2-} + 6 Fe^{2+} + 14H^{+} \to 2Cr^{3+} + 6 Fe^{3+} + 7H_2O$

Calculating the average volume of the dichromate:

$(i)\ 13.8 - 2.3 = 11.5 \ ml\\\\(ii)\ 24.4 - 13.8 = 10.6\ ml\\\\(ii)\ 35.2 - 24.4 = 10.8 \ ml\\\\(iv)\ 45.9 - 35.2 = 10.7\ ml$

$Mean\ volume = 10.9\ ml = 0.0109\ L\\\\moles\ Fe^{2+} \ titrated = 0.01500 \ L \times 0.07\ \frac{mol}{L} = 0.00105 \\\\moles\ Cr_2O_7^{2-}\ required = 0.00105\ mol\ Fe^{2+} \times 1 \ mol\ \frac{Cr_2O_7^{2-}}{6 \mol\ Fe^{2+} } = 0.000175 \ moles\ Cr_2O_7^{2-}\\\\Concentration \ of\ Cr_2O_7^{2-} = \frac{0.000175\ moles}{0.0109\ L} = 0.01606\ M\\\\$
