<span>predicting the boiling point of a liquid, given its pressure</span>
The balloon will shrink in the freezer. This a good way to demonstrate that a gas's volume and/or pressure will decrease when the temperature of the gas decreases.
h2o?
Explanation:
h2 then take away the 2 in o2 then combine
Valence electrons in NH2Cl:
=1(5)*2(1)*1(7)
=14
So there are 14 valence electrons in NH2Cl
As each stick represents an valence electron pair.
And there are 14 valence electrons, so there can be 7 valence electron pairs.
And for 7 valence electron pairs, 7 sticks needed.
Two equivalents of NaOH are needed to fully neutralize the solution.
<h3>What is a neutralization reaction?</h3>
A neutralization reaction involves the reaction of an acid and a base to form salt and water. The reaction is exothermic in nature.
For example,

During the titration of
it gives
.

To neutralize these
, 2
is needed which come from 2 equivalents of NaOH

Therefore, 2 equivalents of NaOH are needed
