The question asks about the average kinetic energy, so it is related only to temperature. Then the answer is (3) with the highest temperature.

Answer: The correct answer is option 3.

Explanation: Average kinetic energy is defined as the energy of motion of the particles of a system. It is a measure of Kelvin Temperature.

Mathematically,

K=\frac{3}{2}\frac{R}{N_A}T

where,

K = kinetic energy of the molecules measured in joules.

R = Gas constant = 8.314Jmol^{-1}K^{-1}

N_A = Avogadro's number = 6.022\times 10^{23}atoms/mol

T = Temperature in kelvins.

Kinetic energy is directly proportional to the temperature of the system.

\text{Kinetic energy}\propto \text{Temperature}

More the temperature, more will be the kinetic energy of the molecules.

Hence, the correct answer is Option 3.

Which element is the least reactive? Neon, Chlorine, Gallium or Tin
Katen [24]
Noble gases are supposed to be the least reactive elements so I’m assuming Neon would be the most least reactive out of all of them.

How many grams of aluminum chloride are needed to react completely with 1.084g lithium sulfide?
Oksi-84 [34.3K]
Molar mass :

Li₂S = <span>45.947 g/mol

AlCl</span>₃ = <span>133.34 g/mol

</span><span>3 Li</span>₂<span>S + 2 AlCl</span>₃<span> = 6 LiCl + Al</span>₂S₃

3 * 45.947 g Li₂S ----------> 2 * <span>133.34 g AlCl</span>₃
1.084 g Li₂S ----------------> ?

Mass Li₂S = 1.084 * 2 * 133.34 / 3 * 45.947

Mass Li₂S = 289.08112 / 137.841

Mass Li₂S = 2.0972 g 

hope this helps!

Color - Hue of an object as perceived by humans
Concentration - Amount of one substance in a mixture
Density - Mass per unit volume of a substance
Dielectric constant - Storage and dissipation of electric and magnetic energy
Ductility - Ability of a substance to be stretched into a wire
Distribution - Number of particles per unit volume in single-particle phase space
Efficacy - Capacity to produce an effect
Elasticity - Tendency of a material to return to its former shape
Electric charge - Positive or negative electric charge of matter
Electrical conductivity - A material's ability to conduct electricity
Electrical impedance - Ratio of voltage to AC
Electrical resistivity - How strongly a flow of electric current is opposed
Electric field - Made by electrically charged particles and time-varying magnetic fields.
Electric potential - Potential energy of a charged particle divided by the charge
Emission - Spectrum of frequencies of electromagnetic radiation emitted
Flexibility - Pliability
Flow rate - Amount of fluid which passes through a surface per unit time.
Fluidity - Flows easily
Freezing point - Temperature where a liquid solidifies
Frequency - Number of repetitions in a given time frame
Hardness - How resistant solid matter is to external force
Inductance - When the current changes, the conductor creates voltage
Intrinsic impedance - Ratio of electric and magnetic fields in an electromagnetic wave
Intensity - Power transferred per unit area
Irradiance - Power of electromagnetic radiation per unit area
Length - Longest dimension of an object
Location - Place where something exists
Luminance - Amount of light that passes through a given area
Luminescence - Emission of light not resulting from heat
Luster - The way light interacts with the surface of a crystal, mineral or rock
Malleability - Ability to form a thin sheet by hammering or rolling a material
Magnetic moment - Force that the magnet exerts on electric currents and the torque that a magnetic field exerts on it
Mass - An object's resistance to being accelerated
Melting point - Temperature where a solid changes to a liquid
Momentum - Product of the mass and velocity of an object
Permeability - Ability of a material to support a magnetic field
Smell - Scent or odor of a substance
