Gina's group classified their mineral samples based on relative hardness. They considered the minerals that have a hardness of l

ess than five as relatively soft, and those with a hardness of five or above as relatively hard. They showed their groupings in a table.
A 2 column table with 3 rows. The first column is labeled Relatively soft minerals with entries: Bornite, Chalcopyrite, Goethite. Second column is labeled Relatively hard minerals with entries: Hematite, Pyrite, Pyrrhotite.

What does Gina’s group need to do to correct the information in the table?

Bornite needs to be switched with pyrite.
Pyrite needs to be switched with goethite.
Goethite needs to be switched with pyrrhotite.
Pyrrhotite needs to be switched with hematit

a mixture contains two or more substances that are physically combined and there is no electron bonding
crimeas [40]


True.

A mixture is composed of two or more pure substance that are physically combined but are not combined chemically and thus no electrons (of their atoms) are involved.

The primary properties of a mixture include:

1. The components of a mixture are easily separated

2. The components each keep their original properties.

3. The proportion of the components may vary.

There are two main categories of mixtures:

1. Heterogeneous mixtures - substances are not evenly distributed e.g. oil and water mixture

2. Homogeneous mixtures - substances are evenly distributed throughout the mixture e.g. salt water, air.
