The Lewis structure of which molecule requires resonance structures?A.) MgCl2B.) SiO2C.) SO2D.) OCl2

Chemistry
1 answer:
inna [77]3 years ago
4 0

Answer:  C.) SO2

Explanation:  Sulfur Dioxide is the gaseous molecule which can show the resonance through lewis dot structure due to the presence of lone pairs of electrons present on all of the three atoms of the molecules. Moreover , Sulphur forms pie bond with the oxygen using p orbitals which forms a network of the conjugated system that help to elaborate the reason of the formation of the resonance structure.

Options (a), (b), and (d) cannot form resonating structures as they involve the formation of the chemical bonds through single sigma bond.

What is the temperature of 0.750 mol of a gas stored in a 6,050 mL cylinder al 221 atm?
Rasek [7]

Answer:

T = 246 K

Explanation:

Given that,

Number of moles, n = 0.750 mol

The volume of the cylinder, V = 6850 mL = 6.85 L

Pressure of the gas, P = 2.21 atm

We need to find the temperature of the gas stored in the cylinder. We know that,

PV= nRT

Where

R is gas constant

T is temperature

So,

T=\dfrac{PV}{nR}\\\\T=\dfrac{2.21\times 6.85}{0.75\times 0.0821}\\T=245.85\ K

or

T = 246 K

So, the temperature of the gas is equal to 246 K.

it is method used to separate particulates from a liquid by allowing in the solids to settle at the bottom of the mixture​
wariber [46]

Answer:

Decantation

Explanation:

Decantation is one of the process of separating mixture containing solid and liquid. In this process, gravity plays a very important role. The solid part of the mixture is allowed to settle down. The liquid is removed and separated in another container. It is a process that helps in the purification of the liquid. The particles that are insoluble settles down and is further subject to be separated from the mixture.
