Steam is water in the gas phase, which is formed when water boils. Steam is invisible however steam often refers to wet steam the visible mist or aerosol of water droplets formed as the water vapor condenses.

Question 4 (1 point)
Rainbow [258]

а о

Explanation:

 The given cation:

           (Rf₂Al₂F₃)³⁺

The oxidation number gives the extent to which a specie is oxidized in a reaction.

This number is assigned based on some rules:

  • Elements in combined state whose atoms combines with themselves have an oxidation number of zero.
  • The charge carried on simple ions gives their oxidation number.
  • Algebraic sum of all the oxidation numbers of atoms in neutral compound is zero. In an ion with more than one kind of atom, the charge on it is the oxidation number.

for the specie given;

Known:

  oxidation number of Al = +3

                                      F = -1

                          charge = +3

    let the oxidation number of Rf = k

        2k + 2(3) + 3(-1) = +3

          2k + 6 - 3 = 3

            2k = 0

              k = 0

The oxidation state of rutherfodium is 0

If you compare the egg to a cell, what did you learn about how water moves into or out of a cell
sleet_krkn [62]

If we compare a cell with an egg there is a major difference between the outer membrane

in case of cell they are bounded by semi permeable membrane  

The semi permeable membrane is a selectively permeable membrane which allows the movement of only solvent molecule and not solute molecules through it.

So water can move into or out of the cell through cell membrane by a special physical process known as osmosis.  

the water will move from a low concentration gradient to high concentration gradient.

If a sample of air initially occupies 240L at 2 atm how much pressure is required to compress it to 20L at constant temperature
IceJOKER [234]

Answer:

24 atm.

Explanation:

From the question given above, the following data were obtained:

Initial volume (V₁) = 240 L

Initial pressure (P₁) = 2 atm

Final volume (V₂) = 20 L

Temperature = constant

Final pressure (P₂) =?

The final pressure required, can be obtained by using the Boyle's law equation as shown below:

P₁V₁ = P₂V₂

2 × 240 = P₂ × 20

480 = P₂ × 20

Divide both side by 20

P₂ = 480 / 20

P₂ = 24 atm

Thus, the final pressure required is 24 atm.
