Answer:
The rate of change is -2
Step-by-step explanation:
f(b)-f(a) 12-2 10
---------- = ------------ = -------- = -2
b-a 1-6 -5
The answer is c. 23 degrees. 697-360 is 337. 360-337 is 23.
Answer:
Step-by-step explanation:
<u>The first time:</u>
- 16 m up and 16 m down = 32 m
The second time and each time after, half of the previous distance
<u>This is a GP with the first 6 terms:</u>
<u>Sum of the distances:</u>
- 32 + 16 + 8 + 4 + 2 + 1 = 63 m
The amount of heat (in KJ) released when 3.5 moles of CH₄ react is 3115 KJ
<h3>Balanced equation</h3>
CH₄ + 2O₂ -> CO₂ + 2H₂O ΔH = 890 KJ
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy.
<h3>How to determine the heat energy released by 3.5 moles of CH₄</h3>
From the balanced equation above,
1 mole of CH₄ reacted to release 890 KJ of heat energy
Therefore,
3.5 moles of CH₄ will react ro release = 3.5 × 890 = 3115 KJ of heat energy
Thus, 3115 KJ of heat energy were released from the reaction
