a)A compound
b)A heterogeneous mixture
c)An element
d)A homogeneous mixture

Answer 1

Answer:

The answer is d.

Explanation:

Homogeneous mixtures have uniform properties.

Answer 2

A sample contains two substances and has uniform properties. The sample is d)A homogeneous mixture.

d)A homogeneous mixture:

A jeweler has two samples, both of which are identical in appearance and have a consistent composition. They are homogeneous mixtures and can be classed as metallic alloys, according to the sample.

Explanation for incorrect answer:

a)A compound:

Compounds are chemical substances composed of two or more elements chemically bonded together in a certain ratio. so this is the wrong answer.

b)A heterogeneous mixture:

A heterogeneous mixture is made up of two or more different elements or phases. So this is the wrong answer.

c)An element:

An element is a substance with the same number of protons in all of its atoms. So this is the wrong answer.
