What is the significance of the discovery: e = mc2? mass moving at the speed of light has energy. any moving mass emits energy. mass and energy can convert to one another. none of the above

Mass and energy can convert to one another

Explanation:

The mathematical expression E = mc² is known as the Einstein equation. Here:

E= energy

m = mass

c = velocity of light.

The equation shows that mass and energy are inter-convertible and they relate to one another. It implies that a given mass would have an equivalent amount of energy it can produce or generate and also vice versa. We also see that energy is also associated with mass. This equation is very useful in understanding nuclear reactions.

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.
