Answer:
No streak of light will appear.
Reason I given below.
Explanation:
No streak of light will be seen.
This is because as it falls to the moon, the gravitational pull plus the dense atmosphere which was necessary to produce friction when it fell to the earth are not present in this case and as such the whole meteor is not burnt like it did when it fell to the earth.
Answer : The correct option is, (B) 
Explanation :
According to the Bronsted Lowry concept, Bronsted Lowry-acid is a substance that donates one or more hydrogen ion in a reaction and Bronsted Lowry-base is a substance that accepts one or more hydrogen ion in a reaction.
Or we can say that, conjugate acid is proton donor and conjugate base is proton acceptor.
The given equilibrium reaction is,
Here, 
is loosing a proton, thus it is considered as an acid and after losing a proton, it forms 
which is a conjugate base. That means, 
are act as a conjugate acid-base pairs.
Hence, correct option is, (B)
Answer:
Chemical reaction
Explanation:
