Answer:
If you have 1 mole of N2 (or any other gas for that matter) under STP conditions it will occupy a volume of 22.4 L. This is known as the “standard molar volume”. So, if you know the number of moles of gas that you have, you can use a simple ratio (1 mole : 22.4 L) to determine the volume of the gas
Explanation:
A eutectoid is a solid solution and a simple mixture of metals. A single solid transforms into two other solid phases.

Explanation:
Acetylene shows acidic character because carbon is sp hybridized containing 50% s-character which makes –C-H bond highly acidic in nature. The acidic character of –C-H can be easily justified when heated with sodium metal which displaces hydrogen from acetylene forming sodium acetylide.
Answer:
Concentration of 
is 0.675 M
Explanation:
According to balanced equation, 2 moles of KOH neutralizes 1 mol of .
18.90 mL of 2.50M KOH = 
of KOH = 0.04725 moles of KOH
If molarity of is C (M) then-
moles of are neutralized = 
of
Hence, 
or, C = 0.675
So, concentration of is 0.675 M
