Hello!
You have to find what the rule is
12/24 = 0.5
6/12 = 0.5
-6/-12= 0.5
They multiply x by 0.5
the rule is multiply x by 0.5 or y = 0.5x
Hope this helps!
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 is - 15 please mark me brainliest
Isolate the y. Note the equal sign. What you do to one side, you do to the other. Subtract 4.58 form both sides
4.58 (-4.58) + y = 2.5 (-4.58)
y = 2.5 - 4.58
y = -2.08
-2.08 is your answer
hope this helps
