Upper N upper H subscript 4 upper C l (s) right and left arrows stacked above each other upper N upper H subscript 3 (g) plus upper H upper C l (g)
Explanation:
The given equation is;
NH₄Cl ⇄ NH₃ + HCl
This equation is clearly different from the other ones.
- In the reactant going forward, there is a right and left arrows stacked above each other.
- The symbol is ⇄ and it is used to show reversibility of chemical reactions.

Answer:
Option D. Al is above H on the activity series.
Explanation:
The equation for the reaction is given below:
2Al + 6HBr —> 2AlBr₃ + 3H₂
The activity series gives us a background understanding of the reactivity of elements i.e how elements displace other elements when present in solution.
From the activity series of metals, we understood that metal higher in the series will displace those lower in the series.
Considering the equation given above, Al is higher than H in the activity series. Thus, the reaction will proceed as illustrated by the equation.
Therefore, we can conclude that the reaction will only occur if Al is higher than H in the activity series.

The individual numbers which are present in chemical formula is subscript.
<h3>What is chemical formula?</h3>
Chemical formula of any compound of chemistry consist more than one atoms in it and gives idea about the number of atoms present in that compound.
Given chemical formula of glucose is C₆H₁₂O₆.
In the given chemical formula of glucose, number which shows the amount of carbon, hydrogen and oxygen are known as subscripts.
Hence, individual number are subscript.
