Answer : The volume of 
produced will be, 0.8 liters.
Explanation : Given,
Volume of 
= 1.2 L
At STP, 1 mole of substance contains 22.4 L volume of substance.
The given balanced chemical reaction is:
From the balanced chemical reaction we conclude that,
As, 
volume of produced 
volume of
So, 
volume of produced 
volume of
Therefore, the volume of produced will be, 0.8 liters.
The number of moles of b2o3 that will be formed is determined as 4 moles.
<h3>
Limiting reagent</h3>
The limiting reagent is the reactant that will be completely used up.
4 b + 3O₂ → 2b₂O₃
from the equation above;
4 b ------------> 2 b₂O₃
2b ------------> b₂O₃
2 : 1
3O₂ -------------> 2b₂O₃
3 : 2
b is the limiting reagent, thus, the amount of b2o3 to be formed is calculated as;
4 b ------------> 2 moles of b2o3
8 moles -------> ?
= (8 x 2)/4
= 4 moles
Thus, the number of moles of b2o3 that will be formed is determined as 4 moles.

Answer: False</h3>
In solid form, ionic compounds do not conduct electricity. Ionic compounds will conduct electricity when melted to their liquid state. This is due to the electrons being locked in place when in solid form, but liquid form allows for the electrons to move freely.
A substance undergoing thermal expansion will expand when heated, substances will mostly expand when heated but when their cold it will undergo contraction.
