The following is an example of which type of chemical reaction?Na (s) + H2O (l) Imported Asset NaOH (aq) + H2 (g)
lora16 [44]

Answer:

The answer to your question is Single replacement

Explanation:

Data

Chemical reaction

                 Na  +  H₂O  ⇒   NaOH  +  H₂

Single replacement  is a chemical reaction in which a metal replaces the cation of a compound.

Decomposition  is a chemical reaction in which a compound forms 2 or more products.

Double replacement  in this chemical reaction two compounds react interchanging their cations and anions.

Combustion in this chemical reaction the reactants must be a compound with carbon and the other oxygen and the products must be carbon dioxide and water.

Which statement is true about the relationship between entropy and spontaneity? O Spontaneous reactions tend to lead to higher e
dimulka [17.4K]

Answer:

The true statement is: Spontaneous reactions tend to lead to higher entropy.

Explanation:

The spontaneity of a reaction is linked to the value of Gibbs free energy (ΔG°). The more negative is this value, the more spontaneous is a reaction. At the same time, Gibbs free energy depends on enthalpy (ΔH°) and entropy (ΔS°), according to the following expression:

ΔG° = ΔH° - T.ΔS°

We can see that higher entropies (higher ΔS°) lead to more negative ΔG°, thus, more spontaneous reactions.
