Answer:
(C)Angle MRN and Angle NRO
Step-by-step explanation:
A diagram of the given problem is drawn and attached below.
From the diagram:
Option A: Angle PRL and Angle LRM = Angle PRM which is not 180 degrees.
Option B: Angle ORP and Angle MRN are vertically opposite angles and are therefore not linear pairs.
Option C: Angle MRN and Angle NRO are on the line ORM and therefore forms a linear pair.
<u>Therefore, the correct option is C.</u>
100g of ammonia releases 271.18 kJ of heat.
<u>Explanation:</u>
Given:
N₂ reacts with H₂
The reaction is:
2N₂ + 3H₂ → 2NH₃ + 92.2 kJ
According to the balanced reaction:
2 X 17g of ammonia releases 92.2 kJ of heat
34g of ammonia releases 92.2 kJ of heat
100g of ammonia will release = kJ of heat
= 271.18 kJ
Therefore, 100g of ammonia releases 271.18 kJ of heat.
