PLEASE HELP

Answer 1

Answer : The correct options are, $H_2O\text{ and }CO$

Explanation :

Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.

The covalent compound are usually formed when two non-metals react.

Ionic compound : It is defined as the compound which is formed when electron gets transferred from one atom to another atom.

Ionic compound are usually formed when a metal reacts with a non-metal.

(1) Magnesium oxide (MgO) : In this compound, magnesium is a metal and oxygen is non-metal. When magnesium atom donates electron to oxygen atom then it forms an ionic compound.

(2) Water $(H_2O)$ : In this compound, hydrogen and oxygen is non-metal. When hydrogen and oxygen atom share their electron then it forms a covalent compound.

(3) Sodium fluoride (NaF) : In this compound, sodium is a metal and fluorine is non-metal. When sodium atom donates electron to fluorine atom then it forms an ionic compound.

(4) Carbon monoxide $(CO)$ : In this compound, carbon and oxygen is non-metal. When carbon and oxygen atom share their electron then it forms a covalent compound.

Hence, the correct options are, $H_2O\text{ and }CO$

Answer 2

Answer:

H2O and CO

Explanation:

they both form covalent bonds because none both of the elements are non-metal. Mgo and NaF both have metals in them so they would form ionic bonds.

Covalent bonds, two non-metal

Ionic bonds, a metal and a non-metal
