Sodium, atomic radius increases as we go down and right in the periodic table, which means that cesium is the element with the biggest atomic radius as it is located as the farthest bottom right of the periodic table, anyways, the atomic number of aluminum is 13 which means that the distribution of electrons here is K:2, L:8, M:3,, number of levels = the atomic period which the atom is located in, last number in the last electronic level (or the valency) = the atomic group which the atomic is located in, so in this case aluminum is located in group 3 period 3 at the periodic table, we have to find the atom which is located the nearest to the bottom right using the same method, sodium is located in group 1 period 3, boron is located in group 3 period 2, silicon is located in group 4 period 3, nitrogen is located in group 5 period 2,,, so the correct answer is sodium as it’s located at the left of aluminum and closer to the left of the periodic table, albeit being in the same period

A liquid has a density of 1.17 g/cm3, how many liters of the liquid have a mass of 3.75 kg
Luda [366]
<span>There are 1000 cm3 in 1 liters. Hence 1 liter of the liquid would weigh: 1000 cm3 x (1.17 g/cm3) = 1170 gm and there are 1000 gm in 1 kg, so we want enough liters to have a mass of 3.75 kg x 1000 gm/kg = 3750 gm Hence, # of liters = desired mass / # of gm per liter = 3750 gm / 1170 gm/liter = 3.2051282 liters</span>

Two moles of gas A spontaneously convert to 3 moles of gas b in a container where the temperature and pressure are held constant
erica [24]

At constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.

<h3>What is Avogadro's law?</h3>

Avogadro's law states that "equal volumes of all gases, at the same temperature and pressure, have the same number of molecules."

It is expressed as;

V₁/n₁ = V₂/n₂

Given the data in the question;

  • Initial amount of gas n₁ = 2moles
  • Initial volume v₁ = 13.9L
  • Final amount of gas n₁ = 3moles
  • Final volume v₂ = ?

V₁/n₁ = V₂/n₂

V₁n₂ = V₂n₁

V₂ = V₁n₂ / n₁

V₂ = (13.9L × 3moles) / 2moles

V₂ = 41.7molL / 2mol

V₂ = 20.85L

At constant temperature and pressure, If the amount of gas increases to the given value, its volume also increases to 20.85L.
