<u>Answer:</u>
is an acid,
is a base,
is conjugate base and
is conjugate acid
<u>Explanation:</u>
According to Bronsted and Lowry's theory:
An acid is defined as a proton donor while a base is defined as a proton acceptor.
In a chemical reaction, an acid loses a proton to form a conjugate base while a base accepts a proton to form conjugate acid.
For the given chemical reaction:

is losing a proton thus it is an acid to form
which is its conjugate base
is gaining a proton thus it is a base to form
which is its conjugate acid
Hence,
is an acid,
is a base,
is conjugate base and
is conjugate acid
Answer:
it is made up of two or more element
<span>b) a positive metal ion and a negative nonmetal ion.
</span>Because generally ions of non-metal elements (such as the halogens) are negatively charged while ions of metal elements (such as the alkali earth metals) are positively charged. The differences in their changes causes strong electrostatic attraction (an ionic bond).
