Solution
The question seems to be incomplete. However, based on the information given, here's how you can approach it:
-
Mean temperature at start: This is given as 5.2°C.
-
Temperature at end: This is not provided in the question. You would need this information to proceed. Let's assume it is X°C.
-
Temperature rise: This is calculated by subtracting the starting temperature from the ending temperature. So, it would be X°C - 5.2°C.
Without the ending temperature, it's impossible to provide the missing information. Please provide the complete details.

A student carries out an experiment to determine the volume of 2 M sodium hydroxide needed to neutralise a known volume of 2 M hydrochloric acid.As different volumes of sodium hydroxide are added, the student uses a thermometer to measure the initial and final temperature. The change in temperature is then calculated.Which of the following options correctly identifies the variables in this investigation?I DON'T KNOWSUBMIT ANSWER
An insulated calorimeter contains 100 g of water at 22 °C. A chemical reaction causes the temperature to increase by 6 °C. What would be the final temperature of the water if the reactant concentration is cut in half (assume the same starting temperature of 22 °C). Group of answer choices28252231
