A scientist needs to check several parameters before coming
to a conclusion about the amount of water pollution. The scientists needs to
check the amount of dissolved oxygen in the water, temperature of the water,
the clarity of the water, the PH level of the water and also the amount of
bacteria present in the water. There may be other criteria’s, but the mentioned
ones are enough to gauge the amount of pollution in the water. Scientists often
takes fish and aquatic plants from the water to be tested to check the amount
of pollution indirectly affecting these species.

Magma in quiet eruptions has a low content in silica , while in explosive eruptions, it has a high Content in silica. A volcano that erupts quietly has magma that is low in silica. Low-silica magma has low viscosity and flows easily. A volcano that erupts explosively has magma that is high in silica. High-silica magma has high viscosity, making it thick and sticky, thus it flows slowly.

Answer :
(a) The name of
is, potassium dichromate.
(b) The name of
is, lithium oxalate.
(c) The name of
is, copper nitrate.
Explanation:
Ionic compound : It is a type of compound that is made up of the ions of the two different elements in which one element is a metal and another element is a non-metal.
(a) 
The given compound
is an ionic compound. It is made up of two different ions which are potassium ion
and dichromate ion
.
So, the name of
is, potassium dichromate.
(b) 
The given compound
is an ionic compound. It is made up of two different ions which are lithium ion
and oxalate ion
.
So, the name of
is, lithium oxalate.
(c) 
The given compound
is an ionic compound. It is made up of two different ions which are copper ion
and nitrate ion
.
So, the name of
is, copper nitrate.
