Answer: The final temperature will be 
Explanation:
To calculate the specific heat of substance during the reaction.
where,
q = heat absorbed =41840 J
c = specific heat = 
m = mass of water = 200 g
= final temperature =?
= initial temperature = 
Now put all the given values in the above formula, we get:
Thus the final temperature will be

Answer:
depends on the element it's reacting with..
Explanation:
if the another element requires less energy to loose electron then zinc will become negatively charged and hence becomes acidic radical..
normally if it is reacting with element with valency 4 and Atomic number less than it(Ti,Si,C) then it will lose electron and gain positive sign and henve becomes basic radical..
It is make the molecule polar.
