<u>Answer</u>:
Final velocity: 1200 m/s
<u>Explanation</u>:
Formula:
<u>Where</u>:
a = average acceleration
v = final velocity
vo = starting velocity
t = elapsed time
<em>Here the final velocity is unknown which we have to find. The initial is 0 m/s</em>
<em>as it was at rest. The time taken: 150 seconds. Acceleration given 8.0 m/s²</em>
using the formula:
m/s
Answer : The grams of carbon monoxide needed are 148.89 g
Solution : Given,
Mass of iron, Fe = 198.5 g
Molar mass of iron, Fe = 56 g/mole
Molar mass of carbon monoxide, CO = 28 g/mole
First we have to calculate the moles of iron, Fe.
The balanced chemical reaction is,
From the balanced reaction, we conclude that
2 moles of iron produces from the 3 moles of carbon monoxide
3.545 moles of iron produces from the moles of carbon monoxide
Now we have to calculate the mass of carbon monoxide, CO.
Therefore, the grams of carbon monoxide needed are 148.89 g
