Question

steel is an example of a pure substance because it is made up of two different metals melted together. true false question 6 (01.08r mc) (multiple choice worth 4 points) when salt dissolves in water, what type of substance is formed? a heterogeneous mixture, because the different components are mixed unevenly within the substance a heterogeneous mixture because the different components are mixed evenly within the substance

Explanation:

First Question (Steel as pure substance):

A pure substance has a fixed composition. Steel is an alloy (mixture of metals like iron and carbon, often with other elements), so it's a mixture, not a pure substance. Thus the statement is false.

When salt (solute) dissolves in water (solvent), the salt particles spread evenly throughout the water. A homogeneous mixture has uniform composition (components mixed evenly), while heterogeneous has uneven mixing. So the formed substance is a homogeneous mixture. The second option (assuming the second option is "A homogeneous mixture because the different components are mixed evenly within the substance") is correct. But from the given options, the second choice (the one about homogeneous, even mixing) is the answer.

Answer:

false
