DanielleElmas [232]

Answer: The mass of $H_{2}$ liberated is 0.0383 g and the mass of NaH that reacted 0.455 g.

Explanation:

The given data is as follows.

Volume = 0.501 L,

Temperature of gas = $35^{o}C$ = (35 + 273) K = 308 K,

Total pressure = 760 mm Hg

Vapor pressure of water at $35^{o}C$ = 422 mm Hg

Partial pressure of $H_{2}$ = (760 - 422) mm Hg

= 717.8 mm Hg

The chemical equation is as follows.

$NaH + H_{2}O \rightarrow NaOH + H_{2}$

Using ideal gas equation, we will find the moles of hydrogen gas as follows.

PV = nRT

n = $\frac{PV}{RT}$

As we know,

1 atm = 760 mm Hg

717.8 mm Hg = $717.8 \times \frac{1 atm}{760 mm Hg}$

= 0.944 atm

Putting the given values into the above formula we will calculate the number of moles as follows.

n = $\frac{PV}{RT}$

= $\frac{0.944 atm \times 0.510 L}{0.08206 Latm/mol K \times 308 K}$

= 0.0190 moles

Now, we will find the mass of $H_{2}$ as follows.

Mass = Moles × Molar mass

= 0.0190 moles × 2.01588 g/mol

= 0.0383 g

Therefore, mass of hydrogen is 0.0383 g.

As the ratio between $H_{2}$ and NaH is 1:1. So, we will calculate the moles of NaH as follows.

Mass = Moles × Molar mass

= 0.0190 moles × 23.99771 g/mol

= 0.455 g

Therefore, mass of NaH is 0.455 g.

Answer:

I'm feeling nice today so heres the answer

Explanation:

In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.

Explanation:

Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.

The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.

The other options presented are not correct, because

Respiration is a process that occurs in the mitochondria.

Diffusion is a passive transport process that does not require energy.

Cellular recognition depends on membrane proteins that act as specific receptors.
