If a shell can hold a maximum of 32 electrons, what is the value of n?
olga2289 [7]
<span>Begin by classifying which energy level, and indirectly principal quantum number, n, resembles to the N shell. no. of orbitals =n2 In your case, the fourth energy level will contain n=4⇒no. of orbitals= 4^2=16 The number of subshells is given by the principal quantum number. no. of subshells=n In your case, the fourth energy level will have no. of subshells = 4 this is the answer to check: the fourth energy shell will can hold a thoroughgoing of no. of electrons=2⋅42=32 e−</span>

Which parameter is indicative of how far and in what direction a reaction will progress?
nekit [7.7K]

Answer:

Option b, The change in free energy of the reaction (ΔG)

Explanation:

Gibbs free energy is a measure of amount of usable energy in the system.

It is related with enthalpy (H), entropy (S) and temprature (T) as:

G = H - TS

The Gibbs free energy change (ΔG) provide spontaneity of a chemical reaction.

If ΔG is negative, then reaction is spontaneous that means reaction is moving towards forward direction.

If ΔG is positive, then reaction is non-spontaneous that means reaction is moving in backward direction.

If ΔG is zero, then reaction is at equilibrium.

Change in enthalpy only gives informtion about heat involed in a chemical reaction, it does not give information about direction of the reaction.

So, among the given options, option b is correct.

A substance that can behave as either an acid or a base is: anthocyanin a neutral substance an indicator an amphiprotic substanc
s2008m [1.1K]

Answer:

These substances are called amphiprotic. Water, amino acids, hydrogen carbonate ions, and hydrogen sulfate ions are common examples.

Explanation:

A substance is amphoteric (from Greek amphoteros = "each of two") if it can act as an acid or a base.

For example, aluminum hydroxide is amphoteric because it can act as a base and neutralize strong acids.
