Answer:

No.

Explanation:

Outer space would not be an ideal spot for a concert for many reasons. One of which, is that there is no sound in space. On Earth, sound travels through air molecules. In outer space there are no air molecules for the sound vibrations to bounce off of.

Calculate the Molarity (M) of an aqueous solution of HCl which is 35.38% HCl by mass and has a density of 1.161 g/mL.
kozerog [31]

Answer:

11.2 M → [HCl]

Explanation:

Solution density = Solution mass / Solution volume

35.38 % by mass, is the same to say 35.38 g of solute in 100 g of solution.

Let's determine the moles of our solute, HCl

35.38 g . 1 mol/36.45 g = 0.970 moles

Let's replace the data in solution density formula

1.161 g/mL = 100 g / Solution volume

Solution volume = 100 g / 1.161 g/mL → 86.1 mL

Let's convert the volume to L → 86.1 mL . 1L / 1000 mL = 0.0861 L

Molarity (M) → mol/L = 0.970 mol / 0.0861 L → 11.2 M

by trial and error, find the largest number that can be added to 6.022× 1023 without changing its displayed value (as shown on t
harkovskaia [24]
As mentioned, this is a trial-and-error process. I typed in the Avogadro's number 6.022×10²³ then added the largest number I could think of. Since infinity can be thought of as 99999...(and so on), I thought that the number should all be composed of 9. As I add 9 after one another, I ended with about 10 quadrillion before the display changed to 6.022000001×10²³. Therefore, the largest number is: 9,999,999,999,999,999.

From which layer of the atmosphere do particles of air escape into space? will give brainly
svetoff [14.1K]

<u>Answer:</u> The layer from where particles of air escape into space is exosphere.

<u>Explanation:</u>

The atmosphere is divided into layers. There are 5 main layers of atmosphere, which are: Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere.

  1. Troposphere is the lowest layer of the atmosphere where most of the weather occurs.
  2. Then comes the Stratosphere which is about 50 km above the Earth's surface. It contains most of the ozone which is present in the atmosphere.
  3. Then comes the Mesosphere which starts from 50 km and extends upto 85 km from the Earth's surface.
  4. Then comes the Thermosphere which starts from 90 km and extends to between 500 km and 1,000 km.
  5. Exosphere is the last layer of the atmosphere, through which anything escapes the atmosphere to space. This layer extends upto 10,000 km from the Earth's surface.

Hence, the layer from where particles of air escape into space is exosphere.
