which compound contains ionic bonds?
a. c2h6
b. pci5
c. ca3n5
d. sf2

C. Ca₃N₅

Explanation:

A bond between a metal and a non-metal is called an ionic bond. The bond that occurs between two non-metals is called a covalent bond.

Let us check each option and determine the nature of the bond.

A. C₂H₆

This contains 2 carbon atoms and 6 hydrogen atoms. Both carbon and hydrogen are non-metals. So, a covalent bond exists between them .

B. PCl₅

This contains 1 phosphorus and 5 chlorine atoms. Both phosphorus and chlorine are non-metals and hence, a covalent bond exists between them .

C. Ca₃N₅

It has 2 calcium atoms and 5 nitrogen atoms. Here, calcium is metal and nitrogen is a non-metal. Hence, an ionic bond occurs between them.

D. SF₂

It has 1 sulfur and 2 fluorine atoms, both of them being non-metallic. So, covalent bonds are there between them.

From all the options, only option C has an ionic bond. So, option C is correct.

answer

procedural programming, object-oriented programming

explanation

procedural programming is a type of computer programming language that specifies a series of well structured steps and procedures   within its development period of time. it contains a systematic order of statements, functions and commands to complete a computational task or program. it is centered on creating procedures. while object oriented programming is a programming language that is centered on creating objects rather that actions and data rather than logic.. it has four principles which are inheritance, polymorphism, abstraction and encapsulation
