Answer:
Carbon dioxide is a molecule of one carbon and two oxygen atoms. Both elements are nonmetals with a moderate difference in electronegativity. However, the difference in electronegativity is not enough for the atoms to become ions and form an ionic compound. Therefore, carbon dioxide is a molecular compound.
Sodium iodide consists of the metal sodium and the nonmetal iodine. Both elements don't have high electronegativity values, but the difference in their values is large enough for electrons to be transferred between them. Since sodium has a lower electronegativity value, it will be the element that loses electrons. After electrons are transferred, ionic bonds will form between the two elements, resulting in an ionic compound.

What is an ideal gas law?Gases obey an equation of state known as the ideal gas law that is PV = n RT, where n is number of moles of gas and R is the gas constant, 8.314 joules per kelvin per mole.
The ideal gas equation is ,
PV = n RT
P is Pressure of the argon gas
Given, V= Volume of the gas is 1.00 L, mass = 1.25gm
Given, T= Temperature of the gas is 25°C = 298 K (0°C = 273 K)
We know that, R= Gas constant = 0.0821 atm L/K mol
n= moles of gas = given mass/molar mass
= 1.25g / 40g/mol
= 0.0312 moles
P= n RT/V
= (0.0312 * 0.0821 * 298)/1
= 0.763 atm
Partial pressure of argon is 0.763 atm.
In Dalton's law, total pressure is the sum of individual pressures.
P total = P1 +P2
P total = P Ar + P ethane
P ethane = 1 - 0.763
= 0.237 atm
Partial pressure of ethane is 0.237 atm.

Electrolytes are substances that produce ions when they dissolve in water.
What are electrolytes?
When some substances are dissolved in water, they undergo physical or chemical changes, creating ions in solution. These substances form an important class of compounds called electrolytes. Substances that do not release ions when dissolved are called non-electrolytes. A substance is said to be a strong electrolyte if the physical or chemical process that produces ions is inherently 100% efficient (all dissolved compounds produce ions). A solute is said to be a weak electrolyte if only a relatively small portion of the solute undergoes ion production processes.
By measuring the electrical conductivity of aqueous solutions containing substances, substances can be identified as strong, weak, or non-electrolyte. To conduct electricity, a substance must contain free-moving charged species. The best known is the conduction of electricity through metal wires.

the London Dispersion Forces in CS2 are so powerful that they are able to overcome the COS dipole-dipole forces as well as the LDFs. Hydrogen bonding is the intermolecular force that exists in carbonyl sulfide. This substance is frequently employed in several small-scale chemical production processes. The greatest intermolecular force is the Coulomb or electrostatic force, which is also responsible for the ionic bonding of salts like NaCl. The electrostatic force is attractive for atoms with opposing charges, although that is an oversimplification of what actually occurs between atoms.

draw the correct products, in either order, for the following oxidative cleavage reaction.
The correct product of the reaction of 1-methylcyclopent-1-ene in basic medium and hydronium ion is 5-oxohexanoic acid.
What is oxidation reaction ?
An oxidation reaction takes place whenever oxygen interacts with a substance or an element. Taking hydrogen out of the reactant species is another way to describe the process of oxidation. The process of oxidation is the loss of electrons by a molecule, an atom, or an ion.
What is cleavage reaction?
Chemical bonds can be split apart through bond cleavage or bond fission. When a molecule is split into two or more pieces, this is generally known as dissociation.
The permanganate ion adds to the double bond in a cis fashion to form a cyclic permanganic ester.
The intermediate cyclic ester undergoes ready hydrolysis to yield a 1,2 diol.
When heated the diols undergo over-oxidation to form ketone or carboxylic acid depending upon the structure of alkene. When atleast one H atom is attached to alkene carbon carboxylic acid is formed. When both alkene carbon is substituted in both ends by alkyl group ketone is the end product.
Oxidative cleavage is a reaction shown by cyclic alkenes in the presence of oxidizing agent, potassium permanganate results in the formation of alcohols and carbonyls.
The double bond present in 1-methylcyclopent-1-ene undergoes oxidative cleavage in the presence of potassium permanganate in basic medium.
Therefore, the correct product of the reaction of 1-methylcyclopent-1-ene in basic medium and hydronium ion is 5-oxohexanoic acid.
