Answer:
Amount of heat absorbed by water is 2604.54 J.
Explanation:
Amount of heat absorbed by water = 
where m represents mass, C represents specific heat and
represents change in temperature.
Here
g ,
and
= (final temperature - initial temperature) = (29.5-21.2)
= 8.3
So, amount of heat heat absorbed by water
= 
= 2604.54 J
Answer: The products are sodium acetate
and solid silver chloride 
Explanation:
A double displacement reaction is one in which exchange of ions take place. The salts which are soluble in water are designated by symbol (aq) and those which are insoluble in water and remain in solid form are represented by (s) after their chemical formulas.
The reaction of aqueous solutions of sodium chloride and silver (I) acetate is :

Thus the products are aqueous sodium acetate
and solid silver chloride 
Strongest reducing agents are in Group 1 . For example lithium. The strongest oxidising agents are in Group 7 , For example Fluorine.
⛄ (4)HG
-This is because it has a freezing point below standard temperature.
