d/6-d = √(36.5/17) (d is distance from ammonia end, rate = distance/time both have same time)
d/6-d = 1.46
d = 3.56
Fraction = 3.56/6 = 0.593
d/6-d = 1.46
d = 3.56
Fraction = 3.56/6 = 0.593

First, we need to understand that when the vapors of ammonia and hydrochloric acid come into contact, they react to form solid ammonium chloride, which appears as a white cloud.
**Finding the Fractional Distance:**
- Let x be the fractional distance along the tube from the end immersed in the ammonia solution.
- As the tube is U-shaped, the total length of the tube is considered as 1 unit.
- Therefore, the distance from the hydrochloric acid end would be 1 - x.
**Applying Mole Concept:**
- The reaction between ammonia and hydrochloric acid can be represented as:
NH3 (g) + HCl (g) → NH4Cl (s)
- At the point where white cloud first forms, the moles of ammonia and hydrochloric acid that have reacted are in the ratio of their coefficients in the balanced chemical equation (1:1 ratio).
- This means that the ratio of the volumes of ammonia and hydrochloric acid at the point of reaction is also 1:1.
**Using Volume Ratio to Find Fractional Distance:**
- The volume of gas in a U-tube is directly proportional to the fractional distance along the tube.
- Since the volumes of ammonia and hydrochloric acid are in a 1:1 ratio, the fractional distance where the white cloud first forms is also 1:1.
- Therefore, the white cloud first forms at x = 0.595, which corresponds to option B.
By understanding the mole concept and volume ratios in a U-tube setup, we can determine the fractional distance along the tube where the white cloud first forms when ammonia and hydrochloric acid vapors react.
