Answer: 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.

vaieri [72.5K]

Answer:

The answer to your question is 4

Explanation:

Chemical reaction

                C₂H₆  +  O₂  ⇒  CO₂  +  H₂O

           Reactants    Elements    Products

                  2            Carbon              1

                  6            Hydrogen         2

                  2            Oxygen             3

Balanced chemical reaction

                2C₂H₆  +  7O₂  ⇒  4CO₂  +  6H₂O

           Reactants    Elements    Products

                  4            Carbon             4

                 12            Hydrogen       12

                 14            Oxygen           14

When the reaction is balanced the coefficient for CO₂ is 4.
