An ether is a compound that has two functional groups separated by an oxygen. The typical structure appears like this: R - O - R', where R and R' are the functional groups. R and R' can only be alkyl and aryl groups. Take for example the simplest ether, Dimethyl ether. The formula is given as CH3OCH3, where there are two methyl groups on each side of the ether. Notice that CH3 is a methyl group, which is an alkyl group.
Based on the properties of minerals, the following are true:
- Fluorite can de distinguished from quartz based on Color and Hardness.
- Solubility is not a property of minerals.
<h3>Properties of minerals</h3>
- Hardness - minerals can be differentiated based their resistance to be scratched.
- Cleavage - the way minerals break up.
- Color - minerals has different colors but this is not often a reliable property.
Flourite and Quartz have different colors and hardness with Quartz being harder than flourite.
In conclusion, solubility is not a mineral property.

Answer:
Number 1 is A (I'm not sure but i think it is) and Number 2 is correct (I think)
Explanation:
Mass of Hydrogen gas produced : 3.202 g
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Hydrogen gas can be obtained by reacting metals with acids
Reaction of Aluminium(Al) and Hydrochloric acid(HCl)
2Al + 6HCl → 2AlCl₃ + 3H₂
mass of Aluminium : 28.56 g, so mol Al :
From equation, mol ratio of Al : H₂ = 2 : 3, so mol H₂ :
Mass of Hydrogen gas produced :
A) 4
b) 1
