Answer:

A is  Mg^2+

B is K^+

C is Se^2-

D is Cl^-

Ca^2+ lies between  Mg^2+ and K^+

S^2-  lies between K^+ and Se^2-

Explanation:

I have attached an image of the four spheres.

Remember that, cations are smaller in size than the corresponding atom atom because the formation of a cation often involves the removal of an entire shell. Anions are larger in size than the corresponding atom because an electron is added thereby expanding the electron cloud and size of the anion.

From left to right let us designate the spheres as ABCD.

A is  Mg^2+

B is K^+

C is Se^2-

D is Cl^-

Ca^2+ lies between  Mg^2+ and K^+

S^2-  lies between K^+ and Se^2-

A container of gas has a volume of 3.5 L and a pressure of 0.8 atm. Assuming the temperature remains constant, what volume of ga
vovikov84 [41]
<h3>Answer:</h3>

5.6 L

<h3>Explanation:</h3>

We are given;

  • Initial volume, V1 = 3.5 L
  • Initial pressure, P1 = 0.8 atm
  • Final pressure, P2 = 0.5 atm

We are required to calculate the final volume;

  • According to Boyle's law, the volume of a fixed mass of a gas and the pressure are inversely proportional at a constant temperature.
  • That is; P α 1/V
  • Mathematically, P=k/V
  • At two different pressure and volume;

           P1V1 = P2V2

In this case;

Rearranging the formula;

V2 = P1V1 ÷ P2

     = (0.8 atm × 3.5 L) ÷ 0.5 atm

    = 5.6 L

Therefore, the resulting volume is 5.6 L
