Answer:
5444.89 grams of Fe
Explanation:
1) We need the chemical equation for Fe3O4 to find the mole ratio for Fe to Fe3O4. Chemical equation:
3Fe+4H2O → Fe3O4+4H2
The mole ratio of Fe to Fe3O4 is 3:1
2) Now, we find how many grams of Fe are needed to produce 32.5 moles of Fe3O4.
= 97.5 moles Fe needed to produce 32.5 moles of Fe3O4
3) Convert 97.5 moles of Fe into grams. The molar mass of Fe is 55.845g.
= 5444.8875g or 5444.89g.

Answer:
335,000,000,000,000 Hz
Explanation:
3.35 x 10^14 is just scientific notation. This is a way to make a really big number small to write and easier to understand. The exponent on the 10 represents how many times you move the decimal to the right. If the exponent is negative you should move the decimal to the left. Each time the decimal is moved, and there is no pre-existing number, you need to add a zero.
3.35 x 10^14 is equal to
335,000,000,000,000

Explanation:
<span>The law of sines can be solved when you know any two angles of a triangle and a side (AAS-case). The second case is when you know two sides and a non-included angle (SSA-case). Recall law of sines is Sin(A)/A = Sin(B)/B = Sin(C)/C .</span>
