how do I do question 3??
2. A second assumption in this experiment relates to the specific heat capacity of the solution. We will assume the specific heat capacity of the solution is dominated by the specific heat of water. As a result, a value of 4.184 Mg °C) will be used for the specific heat capacity of the solution If MgO is added to 28.9 g of 3M HCI solution in a coffee cup calorimeter, the temperature of the resulting solution increases from 20.4 °C to 32.0 °C. With the assumption above in place, what is qsodn for this reaction. Record your response in kJ o0 0 3. A student determines a value of qun 2.14 kJ for the MgO reaction. Based on this value of Gute, what is the value of 1Inn in kJ?Explanation / Answer
3)
q soln is energy absorbed by the solution. The value is 2.14 KJ
This energy must have been released by reaction.
So,
delta H = -qsoln
= -2.14 KJ
Answer: -2.14 KJ
