Someone helppp please

Explanation:

1. Balanced chemical equation (given)

2. Mole ratios

They are given by the coefficients of the balanced chemical equation:

It means that 4 mol of iron can be obtained from 2 moles of iron oxide. Thus, the conversion factor to go from iron oxide to iron is:

3. Convert 640 tonnes of iron oxide to moles

The symbol for metric tonnes is MT.

Mass of iron oxide: 640 MT × 1,000 kg/MT × 1,000 g/kg = 640,000,000g

4. Convert 4,000,000 of moles of iron oxide to moles of iron

5. Convert 8,000,000 of moles of Fe to mass

You just must multiply by the atomic mass of Fe.

periodic trends is an atom that gets larger as the number of electronic shells increase, the radius of atoms increases as you go down a certain group in the periodic table of elements. in general, the size of an atom will decrease as you move from left to right of a certain period.
