A chemist heats 37.35 g of lead to 67.71 °C , then places the metal sample in the cup of water shown in the interactive. Calculate the final temperature of the water. The specific heat of lead is 0.130 J/g⋅°C and the specific heat of water is 4.184 J/g⋅°C . mass of water: 60.000g
initial temperature of water: 25.00 C

Explanation:

Hello!

In this case, since the calorimetry problems involving how the heat released by a hot substance is gained by the cold substance when they are placed in contact until they reach the thermal equilibrium is mathematically defined via:

In this problem, it is seen that the lead is hot and the water cold, so we can write:

Thus, since it is asked for the final temperature, or equilibrium temperature, we solve for it as shown below:

Then, by plugging in the known data we obtain:

Best regards!

it should be all of them because it asks if you included all of those in your answer

explanation:

one negative thing it that it can kill water animals. another negative thing is it can cause the destruction of ecosystem. one way water pollution can be reduced is to conserve energy.
