Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.

<h3>What is the hardness of any element?</h3>

The hardness of any element may be defined as the capability of a material to oppose the process of deformation and remains in actual shape precisely.

According to the table of hardness scales by Mohs, the increasing order of given hardness of given elements is as follows:

Gypsum < Fluorite < Apatite.

Therefore, Fluorite is harder than gypsum but softer than apatite. Thus, the correct option is B.

Consider the following reaction: 3Fe(s) + 4H₂O(g) ➞ Fe₃O₄(s) + 4H₂(g). To answer the following question: "How many moles of hot

Elodia [21]

Answer: 2

Explanation:

To calculate the moles :

$\text{Moles of solute}=\frac{\text{given mass}}{\text{Molar Mass}}$

$\text{Moles of} Fe_3O_4=\frac{275g}{233.5g/mol}=1.18moles$

$3Fe(s)+4H_2O(g)\rightarrow Fe_3O_4(s)+4H_2(g)$

According to stoichiometry :

1 mole of $Fe_3O_4$ are produced by = 4 moles of $H_2O$

Thus 1.18 moles of $Fe_3O_4$ will be produced by= $\frac{4}{1}\times 1.18=4.72moles$ of $H_2O$

Mass of $H_2O=moles\times {\text {Molar mass}}=4.72moles\times 18g/mol=85.0g$

Thus 85.0 g of $H_2O$ will be required and 2 steps are required to get the answer.
