Examine the given reaction. NH4NO3(s) → NH4+(aq) + NO3–(aq) ΔH° = 25.45 kJ/mol ΔS° = 108.7 J/mol·K Which of the given is correct
kobusy [5.1K]

Answer:

B)−6,942 J /mol

Explanation:

At constant temperature and pressure, you cand define the change in Gibbs free energy, ΔG, as:

ΔG = ΔH - TΔS

Where ΔH is enthalpy, T absolute temperature and ΔS change in entropy.

Replacing (25°C = 273 + 25 = 298K; 25.45kJ/mol = 25450J/mol):

ΔG = ΔH - TΔS

ΔG = 25450J/mol - 298K×108.7J/molK

ΔG = -6942.6J/mol

Right solution is:

<h3>B)−6,942 J /mol</h3>

Answer:

Light energy, water and carbon dioxide

Explanation:

First, let’s look at the photosynthesis equation:

light energy + water + carbon dioxide —> glucose + oxygen

The reactants are what go in and are used to create the products.

In photosynthesis, light energy from the sun, water and carbon dioxide are used to make glucose and oxygen.

Therefore, the reactants are light energy, water, and carbon dioxide.
