The electron configuration of an atom of Chlorine Cl (neutral
Chlorine) is:
1s2 2s2 2p6 3s2 3p5
Now if the Chlorine becomes an ion, it becomes Cl-. So we
can see that 1 electron is added therefore the new electron configuration is:
1s2 2s2 2p6 3s2 3p6
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.
