Answer:
B) X = NAD+ Y = NADH + H+
Explanation:
The reaction catalyzed is a redox, where the alcohol is oxidated to acetaldehyde and NAD+ is reduced to NADH+ + H+
The volume of the rectangle has been given by the product of length, breadth, and height. The mass of the air with a density of 1180 g/m³ is 708.57 gms.
<h3>What is density?</h3>
The density of the substance has been known to be given by the mass's ratio to the volume. The formula for density is given as,
Density = Mass ÷ Volume
Given,
Density = 1180 g/m³
The volume of the rectangle = L×B×H
Substituting the values above,
Mass = Density × Volume
M = 1180 × 1.2 × 10⁻² × 8.34 × 10¹ × 6.0 × 10⁻¹
= 708.57 gm
Therefore, the mass of the air is 708.57 gms.

I believe your answer is B.
Answer:
75%
Explanation:
call realistic moles of N2 in the reaction is a
moles of H2 :3a
moles of NH3: 2a
the moles of residual N2 after reaction: 1-a
the moles of residual H2 after react: 3- 3a
the moles of mixture: 2a+1-a+3-3a=2.5
-> a=0.75
H=0.75/1=75%
