Answer : The amount of in kilojoules released is, -5.53 kJ
Explanation :
Formula used :

where,
q = heat released = ?
c = specific heat of ethanol = 
m = mass of ethanol = 23.4 g
= final temperature = 
= initial temperature = 
Now put all the given values in the above formula, we get:


Therefore, the amount of in kilojoules released is, -5.53 kJ

Answer: AgCl
Explanation:
When the reaction takes place in which the sodium chloride is reacted with silver nitrate then the products formed are sodium nitrate and silver chloride.
NaCl(aq) + AgNO3(aq) ⟶ NaNO3(aq) + AgCl (s)
This reaction is known as precipitation reaction in which the white precipitate of silver chloride is formed.
This precipitate is insoluble and separates out of the solution.
So, the correction answer is AgCl(silver chloride).
Answer:
Light , heat , and sound are examples.
