Answer is: concentration of hydrogen iodide is 6 M.

Balanced chemical reaction: H₂(g) + I₂(g) ⇄ 2HI(g).
[H₂] = 0.04 M; equilibrium concentration of hydrogen.
[I₂] = 0.009 M; equilibrium concentration of iodine.
Keq = 1·10⁵.
Keq = [HI]² / [H₂]·[I₂].
[HI]² = [H₂]·[I₂]·Keq.
[HI]² = 0.04 M · 0.009 M · 1·10⁵.
[HI]² = 36 M².
[HI] = √36 M².
[HI] = 6 M.

Which statement describes how chemical formula such as H20 represent compounds check all that apply
Allisa [31]
<h3>Answer:</h3>
  • They show the elements of make up a compound
  • They show the types of atoms that make up a molecule
  • They show the number of each type of atom in a molecule
<h3>Explanation:</h3>

To answer this question we need to know what is a compound.

  • A compound is a substance that is made by two or more atoms of different elements that are chemically combined.
  • A chemical formula of a compound is a formula that shows the elements that make up a compound and also the types of atoms that make up the molecule.
  • Additionally, the chemical formula shows the number of each type of atom in a molecule.
  • In this case, the chemical formula of a molecule of H₂O shows that it is made up of one hydrogen atom and two oxygen atoms.

Answer:

Explanation:

Density is

mass / volume = d

Mass:

840g

Volume:

7 cm x 4 cm  x 10 cm = 280 cm^3

840g / 280 cm^3 = 3 g/cm^3

Which information should be added to the chart in order find out who ran a greater distance?
Arisa [49]

Answer:

This question is incomplete, the complete question is:

Nancy and Hiyang are training for a race. They entered some of their training notes in a chart. Which information should be added to the chart in order find out who ran a greater distance?

The answer is C). the units used to measure distance each day

Explanation:

According to the question, Nancy and Hiyang are training for a race that involves them recording the distance they ran in a chart. Distance, as a quantity, is measured using different S.I units like metres, kilometers, miles, centimeters, etc.

However, in order to accurately discover whether Nancy or Hiyang ran a greater distance as recorded in their chart, the units used to measure distance each day must be included. This is because the unit of a quantity determines how big or small it is in comparison to another. For example, 20metres is not the same as 20centimetres.

If the unit they used in measuring their distance is not included, it will be impossible to tell what is being measured, talkless of who ran a greater distance
