According to the VSEPR theory, which of the following factors determines the shape of a
Gala2k [10]

Answer:

B only

Explanation:

Using the VSEPR principle, the electron bond pairs and the lone pairs on the middle atom help us predict the structure of the molecule. The shape of a molecule is determined by the position of the nucleus and its electrons. The electrons and the nucleus settle in positions that minimize repulsion and maximize attraction.

A reaction is spontaneous if ΔG is ___?<br> negative, positive, or zero?
amm1812

Answer:

A reaction is spontaneous if ΔG is negative.

Explanation:

  • The change in free energy (ΔG) is the difference between the heat released during a process and the heat released for the same process occurring in a reversible manner.

  • The sign of ΔG gives an indication for the spontaneity of the reaction:

If ΔG is negative, the reaction is spontaneous.

If ΔG = zero, the reaction is at equilibrium.

If ΔG is positive, the reaction is non-spontaneous.
