Answer:
7.28 × 10³ K
Explanation:
Let's consider the following reaction.
N₂(g) + O₂(g) → 2 NO(g)
The reaction is spontaneous when the standard Gibbs free energy (ΔG°) is negative. ΔG° is related to the standard enthalpy of the reaction (ΔH°) and the standard entropy of the reaction (ΔS°) through the following expression.
ΔG° = ΔH° - T . ΔS°
If ΔG° < 0,
ΔH° - T . ΔS° < 0
ΔH° < T . ΔS°
T > ΔH°/ΔS° = (180.5 × 10³ J/mol)/(24.8 J/mol.K) = 7.28 × 10³ K
The reaction is spontaneous above 7.28 × 10³ K.
Answer:
Distancia = 925 metros.
Explanation:
Dados los siguientes datos;
Tiempo = 50 segundos
Velocidad = 18.5 m/s
Para encontrar la distancia recorrida;
Matemáticamente, la distancia viene dada por la fórmula;
Sustituyendo en la fórmula, tenemos;
Distancia = 925 m.
Por tanto, el cuerpo recorrió una distancia de 925 metros.
The density of substance that contain 850 milligrams for every Ml is
0.85 g/Cm³
calculation
<em> </em><em>step 1:</em><em>convert 850 Mg to g</em>
<em>that is 1 mg=0.001 g</em>
<em> 850 mg =? g</em>
<em>= (850 mg x 0.001 g)/ 1 mg=0.85 g</em>
<em>step 2: convert Ml to Cm³</em>
<em> that is 1 Ml = 1 cm³</em>
<em>therefore density =</em><em> 0.85 g/Cm³</em>
The cell membrane is made up of phospholipids, embedded with proteins, and controls the transfer of materials into and out of the cell.
