Question

Sterling silver is an alloy of silver made up of around 93% silver and 7% other metals, such as copper, all blended together to form the substance. What type of mixture is sterling silver?

A heterogeneous mixture, because the different components are mixed evenly within the substance
A heterogeneous mixture, because the different components are mixed unevenly within the substance
A homogeneous mixture, because the different components are mixed evenly within the substance
A homogeneous mixture, because the different components are mixed unevenly within the substance

Answer 1

Answer: The correct answer is a homogeneous mixture, because the different components are mixed evenly within the substance.

Step-by-step explanation:

Homogeneous mixtures are defined as the mixtures in which components are evenly spread throughout the solution. The size and shape of the particles are similar in these mixtures.

Heterogeneous mixtures are defined as the mixtures in which component are unevenly spread throughout the solution. The size and shape of the particles differ in these mixtures.

We are given:

An alloy known as sterling silver which is made up of 93% of silver and 7% of other metals. All these metals are evenly blended to form the alloy. Hence, an alloy is considered as a homogeneous mixtures.

Thus, the correct statement is a homogeneous mixture, because the different components are mixed evenly within the substance.

Answer 2

C. A homogeneous mixture, because the different components are mixed evenly within the substance.

Explanation:

Sterling silver is a solid solution of copper in silver. The copper atoms are mixed evenly among the silver atoms.

A. Wrong. In a heterogeneous mixture the components are mixed unevenly.

B. Wrong. Sterling silver is a homogeneous mixture.

D. Wrong. In a homogeneous mixture, the components are mixed evenly.
