This is a really hard one just tell your teacher its not like she/he will get mad for not doing one question and think you will get it
The balanced chemical equation for reaction of
and
is as follows:

From the balanced chemical equation, 2 mol of
reacts with 1 mol of
.
First calculating number of moles of
as follows:

On rearranging,

Here, M is molarity and V is volume. The molarity of
is given 0.274 M or mol/L and volume 155 mL, putting the values,

Since, 1 mol of
reacts with 2 mol of
thus, number of moles of
will be
.
Now, molarity of
is given 0.305 M or mol/L thus, volume can be calculated as follows:

Therefore, volume of
is 278.5 mL.
Answer
Rapid Combustion
Explanation:
An explosion is a combustion and a quick reaction, That makes it rapid
Explanation:
electrovalent bond covers single bond.
Covalent bond covers double or more bonds.
Nitrogen is a non-metal and aluminum is a metal so the bond would be ionic.
