Answer:
<h2>10 g</h2>
Explanation:
The mass of a substance when given the density and volume can be found by using the formula
mass = Density × volume
From the question we have
mass = 2 × 5
We have the final answer as
<h3>10 g</h3>
Hope this helps you
Answer:
3) O(g) is an intermediate; 2O3(g)→3O2(g)
Explanation:
The decomposition of ozone to yield oxygen occurs in a sequence of steps. The various non-elementary reactions involved constitute the reaction mechanism. In the sequence of reaction steps O(g) serves as an intermediate.
The overall reaction involves the conversion of two moles of ozone to three moles of oxygen as shown in the answer. Thus the O(g) is merely a reaction intermediate.
Answer:
a. Gases ideales: relación entre todas las variables que influyen sobre los gases
Explanation:
La ecuación del gas ideal da la relación entre las variables; presión, volumen, temperatura y número de moles.
Según la ecuación del gas ideal; PV = nRT
P = presión del gas
V = volumen del gas
n = Número de moles del gas
R = constante de gas
T = temperatura del gas
El número de moles de SO2 se obtiene de;
n = PV / RT
n = 0,5 * 25 / 0,082 * 373
n = 12,5 / 30,586
n = 0,41 moles
