What is the molarity of a Sodium Chloride solution if 86.00g of NaCl was dissolved in enough water to form 1000.mL of solution?

Chemistry

Vladimir79 [104]3 years ago

Answer:

1.47 M

Explanation:

First we <u>convert 86.00 g of NaCl into moles of NaCl</u>, using the <em>molar mass of NaCl</em>:

  • 86.00 g ÷ 58.44 g/mol = 1.472 mol NaCl

Then we <u>convert 1000 mL into liters:</u>

  • 1000 mL / 1000 = 1.0 L

Finally we can <u>calculate the molarity of the solution</u>:

  • Molarity = moles / liters
  • 1.472 mol / 1.0 L = 1.472 M

MrRa [10]

Answer:

As you cool a matter to absolute zero, their kinetic energy reduces significantly and the molecules slows down and begins to aggregate together. ... As heat is added, the molecules gain more kinetic energy. This shown in their increase motion. When heat is withdrawn, the particles slows down hope this helped

Phosphorous trichloride and phosphorous pentachloride equilibrate in the presence of molecular chlorine according to the reactio
umka21 [38]

Answer : The value of K_p at this temperature is 66.7

Explanation : Given,

Pressure of PCl_3 at equilibrium = 0.348 atm

Pressure of Cl_2 at equilibrium = 0.441 atm

Pressure of PCl_5 at equilibrium = 10.24 atm

The balanced equilibrium reaction is,

PCl_3(g)+Cl_2(g)\rightleftharpoons PCl_5(g)

The expression of equilibrium constant K_p for the reaction will be:

K_p=\frac{(p_{PCl_5})}{(p_{PCl_3})(p_{Cl_2})}

Now put all the values in this expression, we get :

K_p=\frac{(10.24)}{(0.348)(0.441)}

K_p=66.7

Therefore, the value of K_p at this temperature is 66.7

Think about the animals in an arctic ecosystem. How would those animals adapt over time if global temperatures rise over the nex
brilliants [131]

Given the fact that we are seeing a rise in the temperature of the globe, the artic animals in that ecosystem must adapt by a reduction in the rate of metabolism.

<h3>What is global warming?</h3>

Several evidences continue to emerge that the temperature of the earth have continued to increase and this is largely due to the fact that since the turn of the twentieth century and the rise of industrialization, there have been a rise in the emission of the carbon dioxide and other green house gases into the environment. As a result of this, the temperature of the earth has continued to rise steadily leading to the melting of the ice cover and the destruction of ecosystems that are found around the artic regions of the earth.

Now, we know that an organism is able to adapt to the changes that occur in its habitat by being able to alter some of its structure and function.

Given that the organisms that live in the artic are adapted to cold regions and low temperatures, the metabolic rate of the organisms is high in order to produce heat.

As a result of the rise in global temperatures, the organisms would have to reduce their rate of metabolism.

Several tomato plants are grown indoors next to a sunny window. The plants receive water and fertilizer and remain on the window
mrs_skeptik [129]

You can see my previous answer to this very same question on brainly.com/question/11374210.


The answer is:  option D. Response to environment.


Explanation:


As explained, plants (organisms in general) respond to the stimulus provided by the environment.


Such behavior is named tropism. Tropism may be positive or negative.


When the plant's stem bends toward the window, it is showing positive phototropism, which means that the plant growth response to light such that the stems bend toward light, permiting the leaves to receive more light.


I also mention that while the plant's stems posses positive phototropism they posses negative gravitropism and the roots posses positive gravitropism.


Gravitropism is the response of the plant growth to gravity.


Stems grow away from gravity meaning that this is negative gravitropism, but roots grow toward gravity which is positive gravitropism
