Let the unknow oxidation number b x
1+x+3(-2)=0
x-5=0
x=5
Answer:
the volume will decrease
Explanation:
an increase in temperature will lead to an increase in effective collision which also result in an increase in volume, when the temperature decreases, the volume will decrease
Answer: Option (1) is the correct answer.
Explanation:
When dissolved in water, ammonium phosphate 
completely dissociates into ions and it gets attached to the opposite ends of water.
Therefore, it is soluble in water.
Whereas silver sulfate 
slightly dissolves into water as it gives very less 
ions. Therefore, silver sulfate has low solubility.
On the other hand, both 
and 
are insoluble in water.
Thus, we can conclude that out of the given options, is most soluble in water.
