When it comes to similarities of elements, the best solution is to look at the periodic table. Aside from arranging the elements according to the least to greatest atomic numbers, the columns called groups, have the same electronic configuration in their valence shell. They only differ in the energy levels. Therefore, all elements at the same period of Phosphorus have the same electronic configuration. The answers could be Nitrogen, Astatine, Antimony and Bismuth.
<span>Let's </span>assume that water vapor has ideal gas
behavior. <span>
Then we can use ideal gas formula,
PV = nRT<span>
</span><span>Where, P is the pressure of the gas (Pa), V
is the volume of the gas (m³), n is the number
of moles of gas (mol), R is the universal gas constant ( 8.314 J mol</span></span>⁻¹ K⁻¹) and T is temperature in Kelvin.<span>
<span>
</span>P = 1 atm = 101325 Pa (standard pressure)
V = 13.97 L = 13.97 x 10</span>⁻³ m³<span>
n = ?
R = 8.314 J mol</span>⁻¹ K⁻¹<span>
T = 0 °C = 273 K (standard temperature)
<span>
By substitution,
</span>101325 Pa x 13.97x 10</span>⁻³
m³ = n x 8.314 J mol⁻¹ K⁻¹ x 273 K<span>
n = 0.624 mol
<span>
Hence, the moles of water vapor at STP is 0.624 mol.
According to the </span></span>Avogadro's constant, 1 mole of substance has 6.022 × 10²³ particles.
<span>
Hence, number of atoms in water vapor = 0.624 mol x </span>6.022 × 10²³ mol⁻¹
<span> = 3.758 x 10</span>²³<span>

Yes, because density is mass divided by volume. Density can't change unless a chemical change takes place, because density is how close together the molecules in a type of matter are. For example, the density of water is 1,000 kg/m³.
The answer is water.
That is water is added to cordial to make it more dilute.
Cordial is basically used to describe sweeter distilled spirits . Or it can be used to describe non-alcoholic drink. These drinks can be diluted using water.
So the answer is water, that is water is added to cordial to make it more dilute.
Answer: The volume of product formed is 0.26 L
Explanation:
As 
is the the excess reagent, 
is the limiting reagent as it limits the formation of product.
According to stoichiometry :
2 moles of give = 2 moles of 
Thus 0.01 moles of will give =
of
According to ideal gas equation:
P = pressure of gas = 101.325 kPa = 1 atm
V = Volume of gas = ?
n = number of moles = 0.01
R = gas constant =
T =temperature =
Thus the volume of product formed is 0.26 L
