Which choice is characterized by being malleable?   a. metaloids   b. metals   c. noble gases   d. nonmetals

option B. metals.

Justification:

1) Elements can be classified into three main categories: metals, nonmetals, and metaloids.

The metals constitute the most of the elements, which you can see in a periodic table.

2) Most metals are ductiles and malleables, which means that they can be formed into thin sheets and wires.

3) The nonmetals are either gases or brittle solids, ergo they are not malleables.

4) Metalloids have some metallic properties, son nonmetallic properties, and some intermediate properties. They are not malleable nor ductile. There are only 8 metalloids: boron, silicon, germanium, arsenic, antimony, tellurium, polonium and astatine. They are brittle.

The malleabillity is a typical property of the metals.

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.
