Step-by-step explanation:
because the total sum of each percent is 90%
and it must be 100% as it is a full circle
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:
it would be 140
Step-by-step explanation:
It is 4/5. 20 and 25 have the GCF of 5. Divide both by 5. The answer is 4/5
Step-by-step explanation:
p(x) = 2x^2+8x-12
d(x) = x + 1
r(x) = -13
q(x) = 2x + 6

q(x)+r(x)d(x)
= 2x + 6 + (-13) * x + 1
= 2x + 6 -13 * x + 1
= 2x + 6 - 13x + 1
= (- 11x + 7)
