Both work and energy are measured in Joules (J) in the SI system.

Velocity is a vector quantity as it has both magnitude and direction, while mass, temperature, and speed are scalar quantities.

The magnetic quantum number (m_l) can take negative values, ranging from -l to +l.

The azimuthal quantum number (l) can have a value of 0, which corresponds to an s orbital.

The principal quantum number n can never be negative; it starts from 1.

The principal quantum number (n) is always a positive integer (1, 2, 3, ...).

According to the Pauli Exclusion Principle, no two electrons in an atom can have the same set of all four quantum numbers.

The magnetic quantum number describes the orientation of an orbital in space.

The azimuthal quantum number (l) describes the shape of the atomic orbital.

The azimuthal quantum number (l) determines the shape of the orbital.

The azimuthal quantum number (l) describes the shape of an orbital.

The magnetic quantum number (m_l) describes the orientation of an orbital.

The principal quantum number n is not associated with electron spin; it describes the energy level.

The spin quantum number (m_s) does not affect the energy level of the electron.

The principal quantum number n, azimuthal quantum number l, and magnetic quantum number m_l do not describe the spin of an electron. The spin quantum number s does.

Alkynes can undergo electrophilic addition reactions due to the presence of the triple bond.

Hydroboration-oxidation is a two-step process that converts alkenes into alcohols.

Hydroboration followed by oxidation converts alkynes to cis-alkenes.

Hydrogenation of an alkyne will add hydrogen across the triple bond, converting it to an alkene.

Alkynes can be prepared by the dehydrohalogenation of alkyl halides.

Carboxylic acids can be prepared by the hydrolysis of esters.

Respiration is an exothermic reaction that releases energy, resulting in a negative enthalpy change.

The decomposition of hydrogen peroxide is non-spontaneous under standard conditions, resulting in a positive ΔG.

Sublimation of dry ice (solid CO2 to gas) has a positive ΔH (endothermic) and a positive ΔS (increase in disorder).

The combustion of propane releases a large amount of energy, resulting in the highest enthalpy change among the options.

H2O → H2 + O2 involves the oxidation of water to hydrogen and oxygen, making it a redox reaction.

The combustion of glucose is a redox reaction where glucose is oxidized.

In the reaction Fe2O3 + 3CO → 2Fe + 3CO2, iron (Fe) is reduced as it gains electrons from carbon monoxide (CO).

In the reaction 2H2O2 → 2H2O + O2, the oxidation state of oxygen changes from -1 in H2O2 to 0 in O2, indicating that it is both oxidized and reduced.

The reaction C + O2 → CO2 is a redox reaction because carbon is oxidized and oxygen is reduced.
