1. Which out of the following elements has the lowest electronegativity: Lithium, Beryllium, Magnesium, Sodium

lidiya [134]

The element Sodium (Na) has a low electronegativity of the following elements.
The element Beryllium (Be) has the least metallic character.
The element Sodium (Na) has the largest atom.

<u>Explanation:</u>

Sodium (Na) which is a delicate, shimmering white, profoundly responsive soluble base metal loses an electron to a chlorine iota since it has seven electrons in its valence shell.
It needs one more electron to turn into a steady molecule. It has the most reduced electronegativity of the given components.
Beryllium (Be) is a light, silver-gray, relatively soft metal that is strong but brittle has the least metallic character of the given elements.
Since from left to right in a period, Metallic character decreases while nonmetallic character increases from top to bottom.
Sodium(Na) is the largest atom among the given elements since Atomic size decreases across a period from left to right and increases from top to bottom.

How many moles of argon gas would be present in a 37.0 liter vessel at 45.00 °C at a pressure of 2.50 atm?

Pani-rosa [81]

Answer:

3.54 mol

Explanation:

Step 1: Given data

Volume (V): 37.0 L

Temperature (T): 45.00 °C

Pressure (P): 2.50 atm

Step 2: Convert "T" to Kelvin

We will use the following expression.

K = °C + 273.15

K = 45.00°C + 273.15 = 318.15 K

Step 3: Calculate the number of moles (n) of argon gas

We will use the ideal gas equation.

P × V = n × R × T

n = P × V/R × T

n = 2.50 atm × 37.0 L/(0.0821 atm.L/mol.K) × 318.15 K = 3.54 mol
