Answer:
KMNO4.
KCl.
Explanation:
The first compound contains the polyatomic ion MNO4- (which contains covalent bonds) and the second contains the monatomic ion Cl-.
Answer: The correct answer is [tex]K_2Cr_2O_7\text{ and }KCl[/tex]
Explanation:
Ionic compounds are defined as the compounds which are formed by the complete transfer of electrons from one atom to another atom. In these compounds, oppositely charged ions are attracted towards each other to form a compound.
Covalent compounds are defined as the compounds which are formed by the sharing of electrons between the atoms forming a compound. In these compounds, no ions are formed.
Monoatomic ions are the ions which have only one atom having a charge on it.
Polyatomic ions are defined as the ions which have two or more than two atoms and the atoms form covalent bond.
Potassium ion will form ionic bond with both monoatomic and polyatomic ions, but in polyatomic ions, the atoms form covalent bonds.
Compound of potassium in which both covalent and ionic bonds are present is [tex]K_2Cr_2O_7[/tex] where ionic bond is present between potassium and chromate ions. Covalent bond is present between chromium and oxygen atoms.
Compound of potassium having only ionic bond is KCl, where ionic bond is present between potassium and chlorine atoms.
Hence, the correct answer is [tex]K_2Cr_2O_7\text{ and }KCl[/tex]
