Part I:
Calculate the energy change (q) of the surroundings (water) using the enthalpy equation

qwater = m × c × ΔT.

We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL.

The water has absorbed the heat of the metal. So, qwater = qmetal

Using the formula qmetal = m × c × ΔT, calculate the specific heat of the metal. Use the data from your experiment for the metal in your calculation. Aluminum: q=26*4.18*6.3=684.684, c=q/(m*^T)=3.913 Zinc: q=26*4.18*10.3=1119.404, c=q/(m*^T)=2.608
Iron: q=26*4.18*7.8=847.704, c=q/(m*^T)=3.130
Copper: q=26*4.18*9.2=999.856, c=q/(m*^T)=2.608
Part II:
Calculate the energy change (q) of the surroundings (water) using the enthalpy equation

qwater = m × c × ΔT.

We can assume that the specific heat capacity of water is 4.18 J / (g × °C) and the density of water is 1.00 g/mL. Show ALL your work.

The water has absorbed the heat of the metal. So, qwater = qunknown metal

Using the formula qunknown metal = m × c × ΔT, calculate the specific heat of the metal. Use the data from your experiment for the unknown metal in your calculation. Show ALL your work. A: water q=24.0*4.18*2.3=230.736, c=230.736/(15.262*2.30)=6.573 B: water q=24.0*4.18*6.9=692.208, c= 692.208/(25.605*6.9)=3.918 C: water q= 24.0*4.18*2.8=280.896, c=280.896/(20.484*2.8)=4.897

Conclusion:
Use the given specific heat capacity values below to calculate the percent error of the experimental specific heat capacity that you determined in

In part A of the experiment the two values obtained for the specific heat capacity of the metal were about .0500 J/mol. This is a large deviation, with both of these values identifying very different metals. The average heat capacity identified the metal used as brass. The average heat capacity calculated was .3776 J/mol and the actual heat capacity of brass is .375 J/mol. The second run displayed the closest value to the actual value. A source of error that may have caused a large divide in the calculations could have been when the metal was transferred from the boiling water to the calorimeter. In the first run the metal was not fully submerged on the water from the calorimeter and was uncovered for more than two seconds. The second run was smoother in this section and displayed a value much closer to the actual specific heat capacity of the metal. This error can be prevented with a smoother transfer of the metal from the boiling water to the calorimeter with a pair of tongs that have a rubber tip that has a better grip of the metal.…
