Balance the chemical equation by indicating the number of each species in the appropriate blanks. For this exercise, indicate coefficients of 1 explicitly. Match the numbers in the left column to the appropriate blanks in the chemical equations on the right. Make certain the chemical equation is complete before submitting your answer.

3 Fe (s) + 4 H2O (l) > Fe3O4 (s) + 4 H2 (g)

Explanation:

your question is not completed , perhaps the question is similar to this solution, you can use it .

The balanced equation is

3 Fe (s) + 4 H2O (l) > Fe3O4 (s) + 4 H2 (g)

Explanation: In order to balance an equation we must ensure that the number of atoms of each species on right side of the arrow must be equal to the number of atoms of each species on left side of the arrow.

r just means there's a number of carbon in teh chain. for example rcooh means that after x number of carbon, the chain ends with cooh.

explanation:

oxygen, selenium, tellurium, and polonium.

they're all from the same group as sulfur (group 16).
