Answer: ΔH for the reaction is -277.4 kJ
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
where,
n = number of moles
Now put all the given values in this expression, we get
Therefore, the enthalpy change for this reaction is, -277.4 kJ
The one with higher temperature is the one with NaOH as heatis given off during the neutralization reaction that occurs.
<h3>
What is volume?</h3>
Volume can be defined as the amount of space a substance or an objects occupies usually in a closed container.
Volume is measures in litres.
When water is added to dilute acid like HCl, they become more dilute.
When NaOH is added to HCl, a neutralization reaction occurs.
The student will determine the contents of the flasks by adding 10 ml of hcl to each flask. If the NaOH reacts with the Hcl, there will be an increase in temperature.
The increase in temperature is due to the heat of neutralization of the reaction between NaOH and HCl.

AlBr3(aq) is an ionic compound which will have the releasing of 3 Br⁻ ions ions in water for every molecule of AlBr3 that dissolves.
AlBr3(s) --> Al+(aq) + 3 Br⁻(aq)
[Br⁻] = 0.16 mol AlBr3/1L × 3 mol Br⁻ / 1 mol AlBr3 = 0.48 M
The answer to this question is [Br⁻] = 0.48 M
