The chemical equation provided shows iron rusting to form iron oxide. Use the drop-down menu to choose the coefficients that wil
Brrunno [24]

Answer:

4 Fe + 3 O_2 \rightarrow 2 Fe_2 O_3

Explanation:

The original equation is:

Fe + O_2 \rightarrow Fe_2 O_3

We notice that:

- we have 1 atom of Fe on the left, and 2 atoms of Fe on the right

- we have 2 atoms of O on the left, and 3 atoms of O on the right

Therefore, the equation is not balanced.

In order to balance it, we can add:

- a coefficient 3 in front of O_2

- a coefficient 2 in front of Fe_2 O_3

So we have:

Fe + 3 O_2 \rightarrow 2Fe_2O_3

Now the oxygen is balanced, but the iron it not balanced yet, since we have 1 Fe on the left and 4 on the right. Therefore, we should add a coefficient 4 on the Fe on the left:

4 Fe + 3 O_2 \rightarrow 2 Fe_2 O_3

A 35.0-kg child swings in a swing supported by two chains, each 3.02 m long. The tension in each chain at the lowest point is 41
n200080 [17]

Answer:

Explanation:

Total tension must support the weight of the child and provide the necessary centripetal force.

    2T = m(g + v²/R)

2(414) = 35.0(9.81 + v²/3.02)

  828 = 35.0(9.81 + v²/3.02)

23.65 = 9.81 + v²/3.02

13.847 = v²/3.02

 41.81 = v²

      v = 6.47 m/s

F = 2(414) = 828 N    (ignoring the weight of the chains and seat)
