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.
Answer:
impossible
Step-by-step explanation:
X + X + 1 + X + 2 = 56. To solve for X, you first add the integers together and the X variables together. Then you subtract 3 from each side, followed by dividing by 3 on each side. ...
3X + 3 = 56. 3X + 3 - 3 = 56 - 3.
3X = 53. 3X/3 = 53/3.
X = 17 2/3. Since 17 2/3 is not an integer, there is no true answer to this problem.
Answer:
24
Step-by-step explanation:
75/3 is equal to 25... So, in theory, if you multiply 8 by 3, you should get 24. To check that: 75/24 = 25/8
