How many grams of Fe are needed to create 32.5mol Fe3O4?

Chemistry
1 answer:
Mademuasel [1]2 years ago
5 0

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.

32.5 moles Fe3O4x \frac{4 mole O}{1 mole 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.

97.5 mole Fex\frac{55.845g Fe}{1 mole Fe} = 5444.8875g or 5444.89g.

Which property is characteristic of ionic but not of covalent compounds? 1. low boiling point 2. non-conductor of electricity in
otez555 [7]
Ionic and covalent bonds are both strong intermolecular forces. They are generally both crystalline in structure. But relatively speaking, ionic bonds are much stronger. As a consequence, they have inherent properties of higher boiling points, higher melting points, lower volatility, etc. Also, ionic bonds display conductive properties because they are strong electrolytes. <em>Thus, the answer is 5) higher melting points.</em>

Explain how lone pairs of electrons influence the shape of a molecule.
Ronch [10]

Explanation:

the lone pairs will be negatively charged. these have a repulsion effect on other negatively charged electrons in the shells of atoms. picture a water molecule: the lone electron pair on the top of the oxygen will have a repulsion force on the 2 hydrogen atom's orbiting electrons to cause a bent molecular geometry.

castortr0y [4]

Answer:

Milk, cream, milk solids, sugars, modifying agents and flavourings are blended together in stainless steel vats.
