Answer:
a
Explanation:
Its because ammonium has thee hydrogen atoms
Answer : The correct option is, (D) 
Solution :
Formula used :
where,
Q = heat released = -1300 J
m = mass of water = 40 g
c = specific heat of water = 
= final temperature = ?
= initial temperature = 
Now put all the given values in the above formula, we get the final temperature of water.
Therefore, the final temperature of the water is,
Answer:
Option-B (Table Salt) is the correct answer.
Explanation:
Salt formation takes place when Metal (like Na) and Non-metals (like Cl₂) are reacted. In given statement the reaction will be as follow:
2 Na + Cl₂ → 2 NaCl
Above reaction can be divided as;
Oxidation Reaction:
The Sodium Atom (Na) being metal loses its single valence electron to attain a stable noble gas configuration as,
Na → Na⁺ + 1 e⁻
Reduction Reaction:
The Chlorine Atom being non-metals accepts the electron from Na atom and changes into Chloride ion as,
Cl₂ + 2 e⁻ → 2 Cl⁻
Formation of Salt:
Hence, the Na⁺ and Cl⁻ formed attracts each other and form an Ionic bond as,
Na⁺ + Cl⁻ → NaCl
Note: You should remember that NaCl (Sodium Chloride) is also known as Table Salt :)
