![**Educational Exercise: Calculating Heat Transfer and Caloric Conversion**
**2. Heat Transfer in Chemical Reactions**
*Problem Statement:*
If you added 35.5 ml of an HCl solution to 35.5 ml of an NaOH solution and the temperature increased from 25.5 °C to 36.5 °C, how much heat was transferred in this process? The density of the mixture is 1.00 g/ml. Show your work.
*Explanation:*
This exercise involves calculating the heat transfer when two chemical solutions are mixed. You will need to apply the formula for heat transfer:
\[ q = mc\Delta T \]
Where:
- \( q \) = heat energy (calories or joules)
- \( m \) = mass (grams)
- \( c \) = specific heat capacity (usually in \( \frac{cal}{g \times °C} \) or \( \frac{J}{g \times °C} \))
- \( \Delta T \) = change in temperature (°C)
The density provided will help convert the volume to mass. Assume the specific heat capacity of water if not otherwise given.
**3. Caloric Conversion**
*Problem Statement:*
If a candy bar contains 345 Calories, how many calories is this? Show your work.
*Explanation:*
This exercise asks you to convert food Calories to calories. Recall that 1 Calorie (with an uppercase C, also known as a kilocalorie) is equivalent to 1000 calories (with a lowercase c).
\[ \text{Calories} \times 1000 = \text{calories} \]
This exercise will help you understand the energy content of food in different units.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F71f157fa-fa99-439d-8dc2-5e619e5c8af1%2F154ac28f-9498-4006-9bf3-9d19710e14d1%2F38c9voq_processed.jpeg&w=3840&q=75)
