To balance this equation simply place the coefficient 2 in front of both the iron metal and the iron II oxide FeO.
Answer:
D
Explanation:
The chemical properties of an atom is majorly influenced by the number of electrons which are present in the valence shell of its atom. This number helps us to know if the atom is a metal , non-metal , metalloid, or a noble gas. Properties like electro-negativity and electro-positivity depends on the valence electrons. metals with fewer electrons in their valence shell, like sodium have strong electro-positivity, while non-metals which higher number of electrons in their outermost shell like chlorine have a high electronegativity
Oxygen is the second. The first is nitrogen which makes up 78% of air. Oxygen makes up 21% of air.

H2O is a molecule made of H for hydrogen and O for oxygen. There are 12 of these molecules. The smaller number is the number of atoms of the element to the left of it.
