Answer:
I guess second option i.e. More potential employment opportunities and revenue because collecting recyclable material needs manpower to collect them, and secondary employment in transport i.e. to collect all the material at one place we need transport and so on!
Answer:
calcium hydroxide
lithium phosphate
ammonium sulfide
AgNO3
Explanation:
A polyatomic ion refers to an ion composed of two or more atoms in the ion. In the compounds mentioned, each contains at least one poly atomic ion.
AgNO3 contains NO3^- as its polyatomic ion
calcium hydroxide contains OH^- as its polyatomic ion
lithium phosphate contains PO4^- as its polyatomic ion
ammonium sulfide contains NH4^+ as its polyatomic ion.
The statement that describes a chain reaction brought about by a nuclear reaction is "neutrons <span>released during a fission reaction cause other nuclei to split." This is applicable to fission reactions only wherein atoms split and produce neutrons that also cause further atoms to split, thus creating a chain or series of reactions.</span>
Solution :
<u>Explanation 1 </u>:
Spontaneity of the reaction is based on two factors :
-- the tendency to acquire a state of minimum energy
-- the energy of a system to acquire a maximum randomness.
Now, since there isn't much difference in the bond enthalpies of B-F and B-Cl. So, we can say the major driving factor is tendency to acquire a state of maximum randomness.
<u>Explanation 2 </u>:
A system containing the 
B halides has a 
than a system of 
and 
.
It has the same number of 
, but more distinguishable kinds of 
, hence, more microstates and higher entropy.
