20 centimeters2
Step-by-step explanation:
Pythagorean theorem formula is a^2 + b^2 = c^2
7^2 + 11^2 = 170
You will get the value of c by square-rooting 170
Therefore, the answer is √170
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:
a. −5x−1
b. 11x−1
Step-by-step explanation:
Bearing in mind that a whole will be 5/5, so the full pan is 5/5.
