Which layer of the atmosphere is between the exosphere and the mesosphere

Answers

Answer 1
Answer:

The atmosphere of earth is made of five main layers.

1) Troposphere : This is the lowest part of the atmosphere. Most of the air that makes up the atmosphere is present in this layer.

2) Stratosphere : This layer is present above troposphere and extends up to 50 km. It contains ozone layer which prevents the harmful ultraviolet rays from the sun from entering the lower troposphere

3) Mesosphere : The layer above stratosphere is known as mesosphere.

4) Thermosphere : The region lies above mesosphere.

5) Exosphere : The is the outermost region of the atmosphere.

From the above discussion we can see that the layer that lies between exosphere and mesosphere is Thermosphere

Answer 2
Answer: The Thermosphere is located between the Exosphere and Mesosphere.

How many grams of nh3 can be produced from 3.80 mol of n2 and excess h2?

Answers

The  balanced equation :N2 + 3H2 --> 2NH3

1) Let's find the molar mass of NH3 because it will be needed later.
 To determine the molar mass you have to consult the periodic table and see the atomic mass of each element. If the element is repeted, for example 3 times, you multiple the atomic mass per 3.
NH3= 14 + 1 x 3= 17 g/mol

2) By looking at the balanced equation, you can see that 2 mol of NH₃ were produced with only one mol of N2. How much NH3 will result when we have 3,80 mol of N2?
So now we solve it with a porportion:

2 mol NH3-------1 mol of N2
x               --------3.80 of N2

x= 2 x3,8 = 7,6mol NH3

3)  the only thing left to do is convert the moles obtained, to grams. We can use the formula:
nº of moles x molar mass= mass
7,6mol NH3  x 17 g/mol= mass of NH3
mass= 129,2 grams of NH3

What fraction of the gas phase molecules initially present for 1.0 atm in the chamber are present at 1.0×10−10 torr?

Answers

The fraction of gas phase molecules is calculated by the division of final pressure to the initial pressure.

Fraction =     (1)

Here, initial pressure = 1.0 atm

final pressure =

First, convert torr into atm

1 atm = 760 torr

final pressure =

=

Now, put the value of initial and final pressure in formula (1)

Fraction =  

=  

Thus, fraction of the  gas phase molecules =

HOW MANY LIGHT YEARS DOES IT TAKE TO TRAVEL THE SUN

Answers

It would take 4 light years!!

The light reflected from the surface of the Moon takes only a second to reach Earth. The Sun is more than 8 light-minutes away. And so, if the light from the nearest star (Alpha Centauri) takes more than 4 years to reach us, we're seeing that star 4 years in the past.

If a typical antacid tablet contains 2.0 g of sodium hydrogen carbonate, how many moles of carbon dioxide should one tablet yield? Compare this theoretical value with your results. (Hint: You will first need to convert your mass into moles by dividing by the molar mass of NaHCO3 or Sodium hydrogen carbonate a/k/a baking soda). Please, show all work and think about mole ratios relating CO2 to NaHCO3.

Answers

Given mass of sodium hydrogen carbonate = 2.0 g

First, calculate the number of moles of sodium hydrogen carbonate.

Number of moles =       (1)

Molar mass of sodium hydrogen carbonate = 84 g/mol

Put the values in formula (1)

Number of moles =

= 0.023 mol

Sodium hydrogen carbonate is used to neutralise hydrogen chloride present in the stomach.

The reaction is as follows:

Here, 1 mole of sodium hydrogen carbonate gives 1 mole of carbon dioxide.

Thus, number of moles of sodium hydrogen carbonate is equal to number of moles of carbon dioxide.

0.023 mol of sodium hydrogen carbonate gives 0.023 mol of carbon dioxide for one tablet.

How many ml of cranberry juice is required to prepare a 25 ml 12% cranberry solution using a 20% cranberry stock solution?

Answers

To answer this question, you need to equalize the content of the cranberry for both solutions. The content could be count by multiplying the percentage with the volume of the cranberry juice. Then the calculation would be:

content1= content2
concentration1 * volume1= concentration2 * volume2
12%* 25 ml  = 20%* volume2
volume2= 25ml * 12%/ 20%= 15ml
