The change in enthalpy associated with the change in the water’s temperature is 1254 J.
<h3>What is specific heat?</h3>
The amount of heat required to increase the temperature of one gram of a substance by one Celsius degree is known as specific heat.
Enthalpy change will be calculated as:
ΔH = -cmΔT, where
m = mass of water = 50g
c = specific heat of water = 4.18J/g°C
ΔT = change in temperature = 28 - 22 = 6 °C
On putting values in the above equation, we get
ΔH = -(4.18)(50)(6) = -1254 J
Hence change in enthalpy of the reaction is -1254 J.

The main cause of increased erosion is natural elements like rain, wind and ice. Erosion is the process by which the surface of the Earth gets worn down.
Soil erosion is also a big thing, it is caused by mostly rain that contributes to floods. This stuff is bad for farmers because they do a lot of farming and with erosion increasing the growing crops are decreasing because of erosion.

Hi AP Chemistry student. It seems this experiment is impossible. Sterling Silver cannot be separated so easily with this pathetic equipment. However, if one were to carry this experiment out, I would assume they would need to put the alloy in the graduated cylinder and then somehow filter the silver out through filter paper or Buchner funnel. taking the mass with a stir rod is also helpful for the mass percent calculation. I hope this helps you out, good luck in Mrs. Fischer's class :)
