Question

Which of the following elements are in their standard state?

H2O(l)

O (g)

C (diamond)

H2 (g)

Answer 1

Answer #1

H2(g) is in standard state.

H2O (l) is a compound formed by elements Hydrogen and oxygen. So it is not an element.

O(g) is not standard state as standard state of oxygen is O2(g). Diatomic not monoatomic.

C(diamond) is not standard state as C standard state is C(graphite).

Entropy, denoted by the symbol S, is the thermodynamic property describing the amount of molecular randomness or disorder in a system. It is a state thermodynamic function, meaning that its value does not depend on the path used to arrive at a specific set of conditions. Each system with a specified temperature, pressure, and composition has a unique entropy value. The entropy change, ΔS, is the difference in entropy between two states of a system, such as between the reactants and...
