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.

0.500 mile of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (
SCORPION-xisa [38]

The correct question is as follows: 0.500 moles of potassium oxide is dissolved in enough water to make 2.00 L of solution. Calculate the molarity of this solution (plz help!)

Answer: The molarity of this solution is 0.25 M.

Explanation:

Molarity is the number of moles of a substance divided by volume in liter.

As it is given that there are 0.5 moles of potassium oxide in 2.00 L of water so, the molarity of this solution is calculated as follows.

Molarity = \frac{moles}{volume(in L)}\\= \frac{0.5 moles}{2.00 L}\\= 0.25 M

Thus, we can conclude that molarity of this solution is 0.25 M.

Vladimir79 [104]
If the person had clogged arteries and high blood pressure, then went on a healthy diet, the person would start losing weight. They would have a more stable blood pressure (since they are eating healthy foods, with less saturated fat) and the clogged arteries would look significantly better. He/she might lose her/his risk of developing diabetes, heart disease, cancer, etc. Most of her/his health issues would start to balance out if they started eating a diet low in saturated fat.

I hope this helps!

Identify the ion ratios needed to form neutral compounds from the ions below. The metal ion (cation) is listed first, and the no
Natasha2012 [34]
To figure out the ratios of these compounds, it is important to remember that the charge of these compounds must be <em>neutral</em>.

So in order to make them neutral, you must have specific ratios:

Na^{+}: Br^{-}  =1:1; This is true because they both have a charge of magnitude of 1.

Al^{3+}: Cl^{-}=1:3; We need 3 chlorine atoms because we need to balance out the charge from the 3+ charge of aluminum - therefore since chlorine has a 1- charge, we need 3 atoms.

Mg^{2+}: O^{2-}=1:1; The charges of the magnesium (2+) are balanced with the oxygen charge (2-).

Al^{3+}: O^{2-}=2:3; This is correct because if charges are like this, you must find the least common factor in order to know the ratio. The LCF is 6, therefore, for the atom with a 3+ charge, you need 2 of them, and for the atom with a 2- charge, you need 3 of them. This keeps the charge neutral.

Under the same conditions of temperature and pressure, which of the following gases would behave most like an ideal gas?Ne, N₂,
malfutka [58]

Answer:

Ne

Explanation:

Atomic number of Ne is 10.

Electronic configuration of Ne:

1s^2 2s^2 2p^6

Octet of Ne is complete . Element having complete octet are stable and behave ideal gas.

N_2 and CH_4 are reactive and hence, does not behave as ideal gas.

If you double the volume of a sample of gas and then doubled the volume again without changing its pressure, how would this abso
IRINA_888 [86]

Answer:

Explanation:

Increasing Volume while maintaining constant pressure requires a proportional increase in Temperature so the gas pressure will be maintained as constant.

Consider...

V₁ = V₁     V₂ = 4V₁

T₁ = T₁      T₂ = ?

Charles Law => T ∝ V at constant P ... that is, increasing temperature generates a proportional increase in volume to maintain constant pressure.

Empirical Charles Law Relation is ...

V₁/T₁ = V₂/T₂ => T₂ = T₁(V₂/V₁) = T₁(4V₁/V₁) = 4T₁

Increasing Volume of a gas by 4 times requires a 4 times increase in absolute temperature in order to maintain constant pressure.
