Answer:
A
Explanation:
Element A has 3 electrons in outermost shell so its valency is 3. It will loose 3 electrons to attain stability, as loss of 3 electrons is easier than gain of 5 electrons.
Valency of B is −2 as it will gain 2 electrons to attain stability and combine with other atom.
Valency of A⟶+3
Valency of B⟶−2
(Refer to Image)
Cross multiply valency of A and B
∴A2B3 compound will be formed.
Answer:
It increases the amount of carbon dioxide in the air, enhancing global warming.
Explanation:
When deforestation occurs, carbon dioxide ultimately gets released in the
surrounding environment, causing global warming to increase in proximity
and way. Thus, the answer is greatly supported with legitimate facts.

Answer:
Calcium can be ignited and will when burning react with both oxygen and nitrogen forming calcium oxide, CaO, and calcium nitride, Ca3N2.
Answer:
Explanation:
The original calculation to find the number of moles which is 
can be rearranged to give the equation 
. Therefore the amount of molecules can be found by 
(multiplying by Avogadro's Number)
