Interpretation:
A lab report must be written on Calorimetry covering purpose of the experiment, procedure, observation, analysis and conclusion.
Concept Introduction:
Calorimetry deals with heat transfer among objects with different temperature until thermal equilibrium is reached.

Answer to Problem 6E
- Purpose of the experiment is to find temperature of water (mixture) when water with two different temperatures is mixed.
- In a closed container 100 g water is taken at 50°C temperature. Then 100 g water at 20°C is added to the container and mixed properly. Then the final temperature is measured with a thermometer.
- The temperature of the mixture of water was found to be 35°C.
Explanation of Solution
As per Calorimetry principle, when a hot object is kept in contact with cold object then the hot object will release heat which will be absorbed by the cold object. The process continues until the temperature of both the object is same. This means thermal equilibrium is attained.
In this experiment temperatures of two different water were 50°C and 20°C.
Final temperature will be
(M1, t1) and (M2, t2) are mass and temperature of two different water samples and t is the temperature of the mixed water.
The calculated temperature is matched with the observed temperature. The experiment worked well.

- Predicting the qualitative acid-base properties of salts Consider the following data on some weak acids and weak bases: base acid Κα Kb name formula name formula hydrocyanic acid - 10 HCN 4.9 × 10 pyridine C₂H₂N 1.7 × 10 9 acetic acid HCH3CO2 1.8 × 10 5 hydroxylamine HONH2 1.1 × 10¯ 8 Use this data to rank the following solutions in order of increasing pH. In other words, select a '1' next to the solution that will have the lowest pH, a '2' next to the solution that will have the next lowest pH, and so on. 0.1 M KCN solution pH choose one ✓ 0.1 M C5H5NHCI choose one ✓ 0.1 M NaCH3CO2 choose one ✓ 0.1 M HONH3Br ✓ choose one 1 (lowest) 2 3 4 (highest)arrow_forwardFor this question please solve the first question.
