Is a 1.4% NaCl solution hypertonic, isotonic, or hypertonic

Chemistry

Answer:

1.4% NaCl solution is Hypertonic

Explanation:

A hypertonic solution is type of solution that has a greater concentration of solutes (substance given in a solution) on the outside of a cell when compared with the inside of a cell.

Any solution of sodium chloride (NaCl) in water with a concentration of NaCl higher than that found in physiological saline (0.9%) is considered to be hypertonic

3. A volcanologist discovers a volcano built from alternating layers of lava flow, ash, and cinders.
GenaCL600 [577]

Answer:

Composite volcano

Explanation:

Composite volcanoes are also known as stratovolcanoes. They are characterized by their steep sides and symmetrical features. These types of volcanoes are built slowly from the alternating layers of lava flow, ash and cinders erupting from the conduit system, which accumulate and add to the slopes of the volcano.

If nothing eats a hawk what might eventually happen to the energy that is stored in its body
prisoha [69]
✷ Question: <span>If nothing ever eats a hawk, what might eventually happen to the energy that is stored in its body?

</span><span>✐ Answer: When the hawk passes away, the body will decompose like all living creatures. The hawk's energy throughout the body will be pumped back to the system, forming a lot of energy. </span>

podryga [215]

Answer :

Part 1 : Balanced reaction, 3H_2(g)+N_2(g)\rightarrow 2NH_3(g)

Part 2 : The theoretical yield of NH_3 gas = 440.96 g

Part 3 : The % yield of ammonia is 90.03 %

Solution : Given,

Mass of N_2 = 475 g

Molar mass of N_2 = 28 g/mole

Molar mass of NH_3 = 17 g/mole

Experimental yield of NH_3 = 397 g

<u>Answer for Part (1) :</u>

The balanced chemical reaction is,

3H_2(g)+N_2(g)\rightarrow 2NH_3(g)

<u>Answer for Part (2) :</u>

First we have to calculate the moles of N_2.

\text{Moles of }N_2=\frac{\text{ Mass of }N_2}{\text{ Molecular mass of }N_2}=\frac{475g}{28g/mole}=16.96moles

From the given reaction, we conclude that

1 moles of N_2 gas react to give 2 moles of NH_3 gas

16.96 moles of N_2 gas react to give \frac{2}{1}\times 16.96=33.92 moles of NH_3 gas

Now we have to calculate the mass of NH_3 gas.

\text{ Mass of }NH_3=\text{ Moles of }NH_3\times \text{ Molar mass of }NH_3

\text{ Mass of }NH_3=(33.92moles)\times (17g/mole)=440.96g

Therefore, the theoretical yield of NH_3 gas = 440.96 g

<u>Answer for Part (3) :</u>

Formula used for percent yield :

\% \text{ yield of }NH_3=\frac{\text{ Experimental yield of }NH_3}{\text{ Theoretical yield of }NH_3}\times 100

\% \text{ yield of }NH_3=\frac{397g}{440.96g}\times 100=90.03\%

Therefore, the % yield of ammonia is 90.03 %
