C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.
The formation of a chemical bond between two or more atoms, ions or molecules to form a chemicalcompound is known as chemical bonding. The chemical bonding makes sure the atoms are together in the resulting compound.
Chemical bonding is made possible by an attractive force resulting from the overall loss of energy in the resultant molecule compared to its constituents.
Chemical compounds depend on chemical bonding for their stability. There are various kinds of chemical bonds formed. Covalent bonds and ionic bonds are 2 of the most commonly known chemical bonds.
Covalentbonds are formed by the sharing of electrons and an ionicbond is formed by the electrostatic force of attraction between the atoms.
Therefore, in the given examples, C Cl is a covalently bonded compound with the formula CCl₄. MgCl is an ionic compound with the formula MgCl₂.

The bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl and Mg-Cl ionic bond.
Polar covalent bonds are created between two non-metal atoms or molecules that do consist of different electronegativity. and the electronegativity difference that is not equal to zero and the shared pair of electrons forming a bond between will always be towards the high electronegative atom.
An ionic bond the complete sharing or the electron transfer. Ionic bonds basically form or created when the difference in the electronegativity of the two atoms is great or more as compare to covalent bonds form when the electronegativity is same.
Therefore, bond of the following atoms in C-Cl and Mg-Cl is polar covalent bond in C-Cl and Mg-Cl ionic bond.

(2) hydrogen ion (4) hydroxide ion
An Arrhenius base yields hydroxide ion as the only negative ion in an aqueous solution.
This is defined as a substance which dissociates in water to form hydroxide (OH–) ions.
The hydroxide ion formed from the aqueoussolution is the only negative ion which is why option 4 was chosen.

Arrhenius bases are substances which produces hydroxide ions in solution. The only negative ion in an aqueous solution is the hydroxide ion. The answer is number 4.
The decomposition of Nickel(II) hydroxide produces Nickel(II) oxide and water. The chemical equation is: Ni(OH)2 (s) → NiO (s) + H2O (l).
The decomposition reaction of Nickel(II) hydroxide into Nickel(II) oxide and water can be written as follows: Ni(OH)2 (s) → NiO (s) + H2O (l) . In this reaction, solid Nickel(II) hydroxide decomposes into solid Nickel(II) oxide and liquid water. It’s important to remember that in these reactions, a single, complex reactant breaks down into multiple, simpler products.
