<u>Answer:</u> Antimony ion is the smallest and yttrium ion is the largest.
<u>Explanation:</u>
Atomic radius of an atom is defined as the total distance from the nucleus to the outermost shell of the atom.
An ion is formed when a neutral atom looses or gains electrons.
- When an atom looses electrons, it results in the formation of positive ion known as cation.
- When an atom gains electrons, it results in the formation of negative ion known as anion.
As moving from left to right in a period, more and more electrons get added up in the same shell and the attraction between the last electron and nucleus increases, which results in the shrinkage of size of an atom. Hence, the size of an atom decreases.
The size of the cation is small then their neutral atom because it has less number of electrons while its nuclear charge remains the same. Thus, the nucleus attracts the electron more towards itself and leads to the decrease in size.
We are given three cations:
Yttrium lies in Period 5, group 3 of the periodic table.
Niobium lie in Period 5, group 5 of the periodic table.
Antimony lies in Period 5, group 15 of the periodic table.
So, the order of atomic radii in increasing order follows:
Hence, antimony ion is the smallest and yttrium ion is the largest.
Explanation:
small amount of solute is dissolved in a large amount of solvent. it would not make sense to have more solute and solvent. you can think of it like this, you can dissolve a teaspoon of salt in a litre water but you can't resolve 1 kg of salt in a teaspoon of water.
also, the solute is what is begin dissolved and the solvent is what dissolving the solute so the one day the solvent is dissolved in the solute does not make complete sense.
Explanation:
According to Clausius-Claperyon equation,
The given data is as follows.
= (63.5 + 273) K
= 336.6 K
= (78 + 273) K
= 351 K
= 1 atm, = ?
Putting the given values into the above equation as follows.
=
=
= 3813.1 J/mol
Thus, we can conclude that the heat of vaporization of ethanol is 3813.1 J/mol.
Answer: 2:1
The ratio of hydrogen atoms to oxygen atoms used to make water molecules is always 2:1, no matter how many water molecules are being made.
