What is the final temperature of the solution formed when 0.75 grams of kmno4 is added to 85.5 grams of water at 13.2 degrees celsius in a calorimeter

is the final temperature of the given solution.

Explanation:

When heat is absorbed during reaction enthalpy is positive. To calculate amount of heat absorbed by solution:

To calculate no of moles of molar mass is 158.034 g/mol:

Hence quantity of heat can be calculated as given:

As considered that heat capacity of pure water is same as of solution (means to heat 1 gm of water by 1 degree Celsius the energy required) =

Now it is considered that due to dissolvation, no heat loss occurs and final temperature can be calculated by using specific heat capacity:

The final temperature of the solution is .

he would use the colour black

answers: to make sure that all of the broken pieces of tablet were added to the water, to allow for fair comparison of all three trials, with different particle sizes to avoid experimental error
