<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.
The area where she is flying in windless conditions along the equator is called doldrums. Doldrums is a windless zone at the equator caused by warm rising air. The zone experience bands of showers and storms due to the hot air that rises and cools.
Answer:
Partial pressure of of CO₂ in the product mixture is 0,20atm
Explanation:
The balance equation is:
2CO(g) + O₂(g) → 2CO₂(g)
Total pressure of CO(g) and O₂(g) gases before reaction at 100,0°C and 1,0L is 1,50 atm. You can say:
X₁ + Y₁ = 1,50atm <em>(1)</em>
Where X₁ is initial partial pressure CO and Y₁ is initial partial pressure of O₂
After reaction partial pressures are:
X₂ = X₁ - 2n = 0; <em>2n = X₁</em>
Y₂ = Y₁ - n
Z₂ = 2n
Where Z₂ is final partial pressure of CO₂
After reaction pressure at 100,0°C and 1,0L is 1,40 atm, that means:
1,40 atm = (Y₂ + Z₂)
1,40 atm = Y₁ - n + 2n
1,40atm = Y₁ + n
1,40 atm = Y₁ + X₁/2 <em>(2)</em>
Replacing (1) in (2)
1,40 atm = 1,50atm - X₁ + X₁/2
-0,10 atm = - X₁/2
<em>0,20 atm = X₁</em>.
As 2n = X₁; 2n =<em> Z₂ = 0,20 atm</em>

Answer:
<em>Barometers measure this pressure. ... Changes in the atmosphere, including changes in air pressure, affect the weather. Meteorologists use barometers to predict short-term changes in the weather. A rapid drop in atmospheric pressure means that a low-pressure system is arriving.</em>
