14 Magnetism, solubility, and malleability are physical properties of matter. What makes these properties different from
chemical properties?
A Physical properties relate to elements rather than compounds.
<
B Physical properties appear only after a chemical change occurs.
Physical properties can be observed without attempting to change the identity of the substance.
D Physical properties describe elements in the solid state rather than in the liquid or gas state.

answer:

the reaction is type of combination reaction.

explanation:

on the product side, there are 2 molecules of bonded to fe   which means one atom of fe are combined two molecules of . so, balanced chemical equation becomes :

this reaction follows the reaction type of combination reaction. a combination reaction is defined as chemical reaction in which reactants combines together to form a single product.

the answer is c

tell me if wrong

the answer is c.the valence of the atoms combine .
