What type of intermolecular force is the strongest?

Hydrogen bonding is like a super strong handshake between molecules where hydrogen is involved with highly electronegative elements like oxygen or nitrogen. This makes the bonds stronger than other forces like dipole-dipole or dispersion.

Which of the following processes occurs at the cathode in an electrolytic cell?

In an electrolytic cell, reduction happens at the cathode, which is like gaining electrons. The electrons are added to ions or atoms, reducing them to a lower oxidation state.

What is the empirical formula of a compound with 40% carbon, 6.7% hydrogen, and 53.3% oxygen by mass?

The empirical formula is like a recipe with the simplest ingredients. This compound?s simplest ratio of carbon, hydrogen, and oxygen comes out to be CH2O, meaning for every carbon atom, there are two hydrogens and one oxygen.

In a galvanic cell, what happens at the anode?

The anode is like a battery losing charge. In a galvanic cell, oxidation occurs at the anode, meaning electrons are lost and flow toward the cathode, where reduction happens.

Which of the following best describes a Lewis acid?

A Lewis acid is like an empty seat waiting for someone to sit down. It accepts a pair of electrons, whereas a Lewis base is like the person offering the electrons to fill the seat.

What is the coordination number of the central metal ion in the complex [Co(NH3)6]3+?

The coordination number is like counting how many hands are holding onto the central metal. In this case, cobalt (Co) is held by six ammonia (NH3) molecules, so its coordination number is 6.

Which gas law explains the relationship between temperature and volume at constant pressure?

Charles? Law is like a balloon in the sun ? as the gas inside heats up, the balloon gets bigger. It says that when the temperature of a gas increases, its volume also increases, as long as pressure stays constant.

What is the main characteristic of a buffer solution?

A buffer solution is like a shock absorber for pH. Even if you add a little acid or base, it keeps the pH stable because it contains both a weak acid and its conjugate base (or a weak base and its conjugate acid).

Which of the following describes the process of reducing a ketone to an alcohol?

Reduction is like adding extra electrons to a molecule. In this case, you're adding hydrogen to a ketone, converting it into an alcohol. This process usually involves a reducing agent like NaBH4.

What is the oxidation state of sulfur in sulfuric acid (H2SO4)?

Oxidation state is like counting the charges sulfur carries. In H2SO4, sulfur has to balance the negative charges from the oxygen atoms, so it "gives away" six electrons, giving it an oxidation state of +6.
