Q=mcθ
m= 0.0775 kg
c= 4184 J·kg−1·K−1.
θ= T(final) - T(initial), 95-(-8)
Q=33398.78 J so kJ divide 1000
= 33.39878 kJ
Answer:
Millikan's oil drop experiment measured the charge of an electron. ... Electrically charged oil droplets entered the electric field and were balanced between two plates by altering the field. When the charged drops fell at a constant rate, the gravitational and electric forces on it were equal.

Answer:The copper chloride did not fully dissolve in water before performing the reaction.
The mass of the copper was not measured with the same accuracy.
Not all of the copper was collected in the filter.
Not enough time was allowed for all of the aluminum to react.
There were impurities in the aluminum.
Answer:
The concentration of the Cu2 in the 100.0 ml volumetric flask is 0.0592 M
Explanation:
In the first dilution, Cu2 was diluted ten times (25 / 250 = 1/10). Then, this dilution was diluted again, but now five times (20 / 100 = 1/5). In total, the solution was diluted 50 times (1/10 * 1/5 = 1/50). The final concentration will be 2.96 M / 50 = 0.0592 M
