Explanation

The correct Arrhenius equation is K = Ae^(-Ea/RT).

In this equation, K is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the universal gas constant, and T is the absolute temperature in Kelvin.

This equation illustrates how the rate constant increases with temperature and decreases with higher activation energy.

Explanation

Adding NH4Cl to an NH4OH solution can indeed decrease the ionization of NH4OH.

Due to the consumption of NH4+ and OH- ions in the formation of NH4Cl.

Explanation

Heat energy is responsible for changing the state of matter.

Such as:

• Melting (solid to liquid).
• Freezing (liquid to solid).
• Evaporation (liquid to gas).
• Condensation (gas to liquid).

Explanation

Folic acid is not an amino acid; it is a B vitamin (B9) important for DNA synthesis and repair.

In contrast, lysine, glutamic acid, and glycine are all amino acids that serve as building blocks for proteins.

Explanation

Dipole moment of H2 =0 ( zero ).

The ionic character exists in H2 molecule but no dipole moment or bond moment exists permanently.

In these diatomic molecules, the shared pair of electrons lies between the nucleus of the two bonded atoms.

Hence, no separation of charges occurs. I.e., these molecules have zero dipole moment.

Explanation

The p orbital has 2 lobes that are oriented in space along specific axes (x, y, and z).

In addition to p orbitals, other orbitals include:

• s orbitals: 1 lobe (spherical)
• d orbitals: 4 or 5 lobes
• f orbitals: 8 lobes
