The correct option is D.
The hydrogen atoms that are attached to the nitrogen atom in the ammonia molecule are capable of forming hydrogen bond. The hydrogen bond that exist in the ammonia molecule is the reason why it shows higher boiling point compare to the other hydrides. Hydrogen bond occur in ammonia because ammonia is one of the most electronegative elements.

Answer:
specific heat = 0.951 j/g·°C
Explanation:
Heat flow equation => q = m·c·ΔT
q = heat flow = 4817 joules
m = mass in grams = 140 grams Aluminum
c = specific heat = ?
ΔT = Temperature Change in °C = 98.4°C - 62.2°C = 36.2°C
q = m·c·ΔT => c = q/m·ΔT = 4817j/(140g)(36.2°C) = 0.951 j/g·°C
Answer:
V acid = 51.471 mL
Explanation:
- %v/v = [(compoud volumen)/(solution volume)]×100
∴ V solution = 387 mL
∴ %v/v = 13.3 %
compund volume:
⇒ (V acid)/( V sln) = 0.133
⇒ V acid = (0.133)(387 mL)
⇒ V acid = 51.471 mL
