Write the balanced chemical equation for the following reaction. Phases are optional. Solid iron(I) oxide reacts with hydrogen gas to form solid iron and liquid water. 2Fe+3H, Ol Fe, O,+ 3H2 â 2Fe+ 3H2O(I)

Explanation:

Hello!

In this case, when writing chemical reactions from the given names we must make sure we know the proper formula for each reacted and produced species; thus, since solid iron (III) oxide is , hydrogen gas is , solid iron is Fe and liquid water is just , we can write:

However, since different amount of atoms of iron, hydrogen and oxygen are present at each side of the equation, we balance it by adding the following coefficients to each molecule:

And now it is balanced with two iron atoms, three oxygen atoms and six hydrogen atoms at both reactants and products.

Best regards!

a is the correct answer

nuclear fission produces elements that are heavier than helium.

the elements that are used in nuclear fission and their products are much heavier than helium.
