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.

#SPJ1
Answer:
K: +1
Br: +7
O: -2
Explanation:
O is always -2
K is in group one, so that is its charge
-8+1 is -7, so we flip the sign and that becomes Br
The reason why we flip it is to get a net balance of 0
Variable volume and variable shape:)
Answer:
for given question is 2.79 and is 0.52
{i- vant hoff’s constant ; Kb- constant ; m molarity }
M = no. of moles of the solute present in one kg of solution
