Answer:
+8 J/mol
Explanation:
The following were obtained from the question:
Mole of the compound = 3 moles
Heat Energy used = 24J
Hreaction =?
The heat of reaction is the energy released or absorb during a chemical reaction. It is can obtained mathematically by the following equation:
Hreaction = Heat energy/mole
With the above equation, we can easily find the Hreaction for the question given as follow:
Hreaction = Heat energy/mole
Hreaction = 24J / 3mol
Hreaction = 8 J/mol
Since the compound used the energy, the Hreaction is +8 J/mol

Answer:
<h2>2.57 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question we have
volume = final volume of water - initial volume of water
volume = 22.76 mL - 15.35 ml = 7.41 mL
We have the final answer as
<h3>2.57 g/mL</h3>
