Answer:

D. 224 g

Explanation:

Let's consider the rusting of iron reaction.

4 Fe + 3 O₂ → 2 Fe₂O₃

The molar ratio of Fe to Fe₂O₃ is 4:2. The moles of Fe₂O₃ produced from 2.80 moles of Fe are:

2.80 mol Fe × (2 mol Fe₂O₃ / 4 mol Fe) = 1.40 mol Fe₂O₃.

The molar mass of Fe₂O₃ is 159.70 g/mol. The mass of Fe₂O₃ is:

1.40 mol × (159.70 g / 1 mol) = 224 g

ziro4ka [17]

<u>Given:</u>

Initial velocity (v1) = 0 m/s

Final velocity (v2) = 30 m/s

Acceleration (a) = 6.1 m/s2

<u>To determine:</u>

The time (t) taken to reach the final speed

<u>Explanation:</u>

Use the relation:

Acceleration (a) = [final velocity(v2) - initial velocity (v1)]/time (t)

t = (v2-v1)/a = 30-0/6.1 = 4.92 s

Ans: Time taken is around 4.9 s

Consider the reaction.
Stella [2.4K]

Answer:

when the rates of the forward and reverse reactions are equal

Explanation:

In a chemical system, the reaction reaches a dynamic equilibrium when the rate of formation of product equals the rate of formation of reactants. This implies that both the forward and revered(backwards) reaction are occurring at the same rate.
