C,H,O,+ 3HCI → C,HCl, + 3H20<br> right 5 possible mole ratios
Marina86 [1]

Answer:

Here's what I get  

Explanation:

I think this may be the equation you intended to write:

C₃H₅(OH)₃ + 3HCl ⟶ C₃H₅Cl₃ + 3H₂O

The mole ratios are the ratios of the coefficients in the balanced equation.

Here are some of the possible molar ratios.  

  1. C₃H₅(OH)₃:HCl        = 1:3
  2. C₃H₅(OH)₃:C₃H₅Cl₃ = 1:1
  3. C₃H₅(OH)₃:H₂O       = 1:3
  4.           HCl:C₃H₅Cl₃ = 3:1
  5.           HCl:H₂O       = 3:3
  6.    C₃H₅Cl₃:H₂O       = 1:3

Sort the phrases about the mesosphere and the thermosphere into the correct categories.
kiruha [24]

Explanation:

Before proceeding, let's understand what thermosphere and mesosphere are;

The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere.

The thermosphere is the layer in the Earth's atmosphere directly above the mesosphere and below the exosphere.

The meteors make it through the exosphere and thermosphere without much trouble because those layers don't have much air. But when they hit the mesosphere, there are enough gases to cause friction and create heat.

Temperatures in the mesosphere decrease with altitude. Because there are few gas molecules in the mesosphere to absorb the Sun's radiation, the

heat source is the stratosphere below. The mesosphere is extremely cold.

Satellites and the International Space Station orbit the Earth within the thermosphere.

Mesosphere;

- is directly above the stratosphere

- acts as a barrier to meteoroids

- is very cold

Thermosphere;

- reaches out into space

- is where satellites travel

Calculate the pH of a solution with a [H 3 O + ]=5.6x10 -9 M.
Gre4nikov [31]

Answer:

8.3

Explanation:

pH is the measure of the H+ or H30 (they r the same thing) ions in a solution. it is equal to -log[H+]. [H+]=  Molar concentration of H+ ions.

Which is an example of the electromagnetic force?
Zarrin [17]

First to answer

Answer:

D: Protons that make up a nitrogen atom stays together in the nucleus

This is because a electromagnetic force is responsible for atomic structure, chemical reactions, the attractive and repulsive forces associated with electrical charge and magnetism, and other electromagnetic phenomena.
