Answer:

The concentration of H2CO3 decreases.

Explanation:

Respiration may be defined as the process of exchange of gases between the alveoli, tissues and external environment. The oxygen is inhaled and carbon dioxide is exhaled out during respiration process.

Rapid exhalation of CO2 means the amount of oxygen is more than the carbon dioxide. The concentration of H2CO3 will decrease as less amount of carbon dioxide is available in the body. The concentration of carbon dioxide is directly proportional to the concentration of H2CO3. Hence, the concentration of H2CO3 will decrease.

Thus, the correct answer is option (1).

If there is a constant loss of $CO_{2}~(carbon~dioxide)$ the concentration of $H_{2} CO_{3}~(carbonic~acid)$ will be affected and decrease since $CO_{2}$ is a main component of $H_{2}CO_{3}$ .

Hope it helped,

Pachacha [2.7K]

Answer:

$p = \boxed{\text{593 torr}}$

Explanation:

For this question, we must use Dalton's Law of Partial Pressures:

The partial pressure of a gas in a mixture of gases equals its mole fraction times the total pressure:

$p = \chi p_{\text{tot}}$

Data:

χ = 0.7808

$p_{\text{tot}} = \text{ 760 torr}$

Calculation:

$p = 0.7808 \times \text{ 760 torr}\\\\p= \boxed{\textbf{593 torr}}$

Phosphorus oxychloride has the chemical formula POCl3, with P as the central atom. In order to minimize formal charge, how many

Elina [12.6K]

Answer:

Phosphorus makes 5 bonds with other atoms

Explanation:

$POCl_{3}$ has total 32 number of valence electrons (P has 5 , O has 6 and Cl has 7 valence electrons).

These valence electrons are used to draw Lewis structure of $POCl_{3}$ .

Formal charge on an atom = (no. of valence electrons of the atom)-(no. of covalent bonds attached to the atom)-(no. of electrons in lone pair of the atom)

Applying octet rule (atoms have eight electrons in their valence shell) and minimizing formal charge of $POCl_{3}$ , it has been found that P makes total 5 bonds with rest of the atoms.

Lewis structure of $POCl_{3}$ along with formal charge (in parentheses) has been given below.

En un matraz, disponemos de 100 g de gas oxígeno que se encuentran a 1 at de presión y 273 K de temperatura. Calcular : a) el nú

Misha Larkins [42]

Answer:

Explanation:

Dado que:

masa de oxígeno gaseoso = 100 g

presión = 1 atm

temperatura = 273 K

(a)

número de moles de oxígeno contenidos en el matraz = masa de oxígeno / masa molar de oxígeno

= 100 g / 16 gmol⁻¹

= 6.25 moles

(b) El número de moléculas de oxígeno es el siguiente:

Dado que 1 mol de oxígeno gaseoso contiene 6.023 * 10²³ moléculas de oxígeno.

Entonces, 6.25 moles contendrán:

= (6.25 × 6.023 * 10²³) moléculas de oxígeno.

≅ 3.764 × 10²³ moléculas de oxígeno.

= 2 × 3.764 × 10²³

= 7.528 × 10²³ átomos de oxígeno

(d) Usando la ecuación de gas ideal

PV = nRT

El volumen ocupado por el oxígeno = $\dfrac{nRT}{P}$

Volumen ocupado por oxígeno = $\dfrac{ 6.25 * 8.314 *273}{1}$

Volumen ocupado por oxígeno= 14185.76 m³
