When you are mixing reagents in a separatory funnel it is
important to vent it normally and do so in a method so that is it is not
venting towards anybody. Also be certain to take out the stopper when draining
the lower layer. If you do not take out the stopper, the pressure will not be correct,
and the liquid will not pour out.
Answer:
X3Y2
Explanation:
To represent the chemical formula of the binary compound, the valencies of both elements need to be exchanged.
Valency is the combining power of elements, ions or radicals. It is the value that shows how an element tend to combine with other elements.
In this particular question, the valence of the element X is +2, this means when it enters into chemical combination, it goes in with the power of positive 2. Same goes for the element Y, when it goes into chemical combination, it is expected that it goes in with the negative power of 3.
To completely write the chemical formula of the compound formed from the combination of both, we simply exchange the valency as said above. It must be noted that while the less electronegative element carry a positive or less negative charge , the more electronegative element will carry a negative or more negative charge.
We write the less electronegative element before the more electronegative element while writing the formula of the compound
