Question

A chemist divides a large sample of a mixture into three smaller portions. each of these portions contains different ratios of the component substances that make up the mixture. which description best fits the mixture? a. compound b. element c. heterogeneous mixture d. homogeneous mixture e. pure substance

Answer 1

A heterogeneous mixture is not uniform in composition. Hence, option C is correct.

What is a heterogeneous mixture?

A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture.

This substance is not an element or compound, because different components could be observed in the substance.  

A pure substance is made up of only one type of atom (element) or only one type of molecule (compound), mixtures and solutions are made from two or more types of pure substances.

For example, aluminium is an element and ammonia is a compound.

This substance is not a homogeneous mixture, because different samples of the substance appeared to have different proportions of the components.

Hence, this substance is a heterogeneous mixture.
