For your second question its Diamonds,Rubys, Emeralds.
And for your first question its :Minerals are natural: These substances that form without any human help.

Minerals are solid: They don't droop or melt or evaporate.

Minerals are inorganic: They aren't carbon compounds like those found in living things.

Minerals are crystalline: They have a distinct recipe and arrangement of atoms.

Minerals are solid inorganic substances of natural occurrences.
Examples of minerals that would be considered gems are: Alexandrite, Diamond, Lapis, Paraiba, Ruby, and Topaz. There's 80, those are just a few.

I hope this helps! :>

UNO [17]

Answer:

See Explanation

Explanation:

Given

(a) to (d)

Required

Determine whether the given parameters can calculate the required parameter

To calculate either Density, Mass or Volume, we have

Density = \frac{Mass}{Volume}

Mass = Density * Volume

Volume = \frac{Mass}{Density}

(a) 432 g of table salt occupies 20.0 cm^3 of space

Here, we have:

Mass = 432g

Volume = 20.0cm^3

The above can be used to calculate Density as follows;

Density = \frac{Mass}{Volume}

Density = \frac{432g}{20.0cm^3}

Density = 21.6g/cm^3

(b) 5.00 g of balsa wood, density of balsa wood : 0.16 g/cm^3

Here, we have:

Mass = 5.00g

Density = 0.16g/cm^3

This can be used to solve for Volume as follows:

Volume = \frac{Mass}{Density}

Volume = \frac{5.00g}{0.16g/cm^3}

Volume = 31.25cm^3

(c) 32 cm^3 sample of gold density of 19.3 g/cm^3

Here, we have:

Volume = 32cm^3

Density = 19.3g/cm^3

This can be used to calculate Mass as follows:

Mass = Density * Volume

Mass = 32cm^3 * 19.3g/cm^3

Mass = 617.6g

(d) 150 g of iron, density of Iron = 79.0 g/cm^3

Here, we have

Mass = 150g

Density = 79.0g/cm^3

This can be used to calculate volume as follows:

Volume = \frac{Mass}{Density}

Volume = \frac{150g}{79.0g/cm^3}

Volume = 1.90 cm^3 <em>Approximated</em>
