What is the mole ratio of fe304 to fe?
serg [7]
Answer: 1:3

Explanation:

1) To state the mole ratio of a product and a reactant we need the chemical equation that shows the reaction.

2) In the case of Fe3O4 and Fe, the chemical equation is:

<span>              Fe+H2O → Fe3O4+H2.

3) Now, you balance the equation, which will give you the coefficients of each reactant and product of the chemical reaction:
</span>
<span>              3Fe+4H2O → Fe3O4+4H2

4) From that the mole ratios are:

              3 mol Fe : 4 mol 4H2O : 1 mol Fe3O4 : 4 mol H2.

5) The question requires you to find the mole ratio for Fe3O4 to Fe. Tha is:

            1 mole Fe3O4 : 3 mole Fe

So, the answer is 1:3

A. what is the hybridization of the central atom in cse2?
elixir [45]

The orbital hybridization of the central carbon atom in CSe2 is sp.

In chemical bonding, atomic orbitals may be combined to form appropriate hybrid orbitals suitable for bonding. The orbitals that combine during hybridization must be close enough in energy.

In the compound Cse2, carbon is the central atom bonded to two selenium atoms. The carbon atom in CSe2 is sp hybridized.
