This question is recalling the behavior of real gases in contrast to ideal gases, defined by the van der Waals equation and the ideal gas law respectively, and a reason behind the increasing discrepancy is required.
In such a way, we can start by considering the attached picture in which the choices are shown and clearly, the answer is "as the polarity of the molecules increase".
The aforementioned can be explained with the concept of intermolecular forces, because ideal gas theory states that ideal gas molecules do not interact one to another, and, as the polarity of the molecules increase, these intermolecular forces increase their frequency and strength, and will lead to the formation of associations, which fail to be numerically modelled by simple equations of state such as van der Waals, Redlich-Kwong, Peng-Robinson, etc,.
These associations are, of course, thoroughly neglected by the ideal gas law whereas the ones included in the van der Waals equation, which are not the most reliable, merely attempt to approach this phenomenon, which cause the mentioned discrepancy. As an additional data, robust equations of state, such as CPA (cubic plus association) are able to provide reliable results when working with highly polar gases but turn out really tough to work with due to its mathematical complexity.

Which charge does iron (Fe) have in iron sulfate (FeSO4)?
A) -1
B) +2
C) -2
D)+2
Answers
The charge on iron (Fe) in iron sulfate (FeSO₄) is equal to +2. Therefore, option (D) is correct.
What are the ionic charges?The ionic charge can be described as the oxidation number of the chemical species. The cation carries a positive ionic charge while Anion carries a negative ionic charge. The number of electrons gained or lost by an atom decides the charge carried by ions.
In the modern periodic table, the elements placed on the left side are electropositive and act as metals because they can donate one or more electrons. The elements placed on the right side are electronegative as they can accept one or more electrons and get a negative charge on their ions.
Considering that the charge on the iron is x, We know that charge on the sulfate ion is -2.
x - 2 = 0
x = +2
Therefore, the charge on iron (Fe) in iron sulfate (FeSO₄) is +2.

The molar mass of water is 18 g. Given that there are 0.23 teaspoon for every 1 g. Thus , for 18 g there would be 4.14 teaspoons.
What is one mole?Any substance that contains 6.022 × 10²³ number of atoms is called one mole of that substance. The mass of a compound or molecule containing these much atoms is called its molar mass.
Molar mass of water is 18 g. Thus, it means that one mole of water weighs 18 g. Given that for every 1 g of water there are 0.23 teaspoon. Thus, number of teaspoons for one mole or 18 g of water is:
number of teaspoons = 18 g × 0.23 /1 g
= 4.14 teaspoons.
Therefore, 4.14 teaspoons are required for one mole of water.

1. How many atoms are in 1.00 mole of H?
Answers
Answer:
6.022 × 1023
Explanation:
1 mole of H:
The definition of Avogadro's number of 6.022 × 1023/mole is the number of atoms or molecules per one gram atomic weight. For one gram atomic weight of hydrogen with an atomic weight of one gram, one mole of hydrogen contains 6.022 × 1023 hydrogen atoms. 1.45⋅6.02⋅1023≈8.73⋅1023 hydrogen atoms.
1 mole:
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro's Number (6.0221421 x 1023).
in an H:
H: 2×2×4=16 atoms of hydrogen. C: It only appears once and without a subscript, so 1×4=4 . O : Like carbon, it's 1×4=4 .
1.00 mole:
One mole is equal to 6.02214179×1023 atoms, or other elementary units such as molecules.
