The quantity of energy released when an electron is added to the valence shell of a gaseous, neutral, and isolated atom is known as electron affinity.

Propylene has no serious health or explosion risks and has a lot of energy in its triple bond.

Silicon tetrachloride (SiCl4) is a colorless liquid that is created when silicon powder is heated and exposed to chlorine gas.The balanced chemical equation for this reaction is: Si(s) + 2C12(g) → SiCl4(1)
Consequently, the colorless liquid that is created has the formula SiCl4, or silicon tetrachloride. Therefore, option B—SiCl4—is the right response.

Typically, one mole of H2 is added to vegetable oils to harden them.

Paraldehyde can be created by polymerizing formaldehyde (CH2O).

Carbon-12 has an atomic mass of 12 and carbon-14 has a mass of 14. It is stated that carbon-12 is 70% (i.e., 0.7) and carbon-14 is 30% (i.e., 0.3).

Average atomic mass is equal to (abundance of carbon-12 x carbon-12 atomic mass) + (abundance of carbon-14 x carbon-14 atomic mass). (0.7 x 12) + (0.3 x 14) = 12.6 amu.

The orbitals get larger as the energy levels rise. Thus, 4s>3s>2s>1s is the increasing order of the hybrid orbital’s size.

Kinetic evidence indicates that the base and substrate have a direct relationship with the rate of reaction. It is referred to as “second order kinetics” and is contingent upon the substrate and base concentrations.

1 inch of Hg = 2.54 cm of Hg

30.2 inches of mercury = 30.2 (2.54) cm of mercury = 30.2 (5.08/2) = 15.1(5.08) = 76.7 cm of mercury = 767 torr

760 Torr = 1 Atm

Atm = 1.01 = 767 torr = (767/760) atm

1.36 cm Hg = 1 cm H2O

Hg = 76.7/1.36 cm = 76.7 cm 56.3 cm of H2O H2O = 563 mm H2O

Consequently,

30.2 inches of Hg = 767 cm Hg = 563 mm H2O = 1.01 atm Hg = 767 torr

Thus, 1.01 atm is the appropriate choice.

The right choice is B.
This choice is accurate as covalent bonds are created when two electrons are shared in order to get the closest noble gas configuration.

Answer: This question can be answered by remembering the electrochemical series’ order:

It is evident from this that OH-will be released at the anode as O2 and H+ will be released at the cathode as H2 in preference to Na+.

Unit of K = (Unit of Rate) / (Unit of [A])

(mol/L/s) / (mol/L) is the unit of K.

K = 1/s as a unit

Consequently, “1 per second” or “s-1” is the unit of the rate constant (K) for this first-order reaction. Therefore, option C is the right response.

Acids are substances that react with carbonates and bicarbonates to produce CO2.

Strong acids, carboxylic acids can react with sodium carbonate to produce carbon dioxide.

2 CH3-CH2-COOH + Na2CO3 → 2 CH3-CH2-COONa + CO2 + H2O

Alkyl halides, sometimes referred to as haloalkanes, are organic compounds with an alkyl group bound to a halogen atom. They lack a carboxylic acid functional group and have no structural resemblance to carboxylic acids.

Carboxylic acid derivatives include the following.
