Sonbull [250]3 years ago
8 0

Answer:

They all belong to the p block in the periodic table

Explanation:

Let us examine the electronic configuration of each element;

Oxygen - [He] 2s2 2p4

Silicon - [Ne] 3s2 3p2

Selenium - [Ar] 4s2 3d10 4p4

A common thread that joins all the elements listed above is that they all belong to the p-block in the periodic table. They could be collectively referred to as p-block elements.

A Rectangular Prism has a height of 4cm, a width of 5cm, a length of 1.2 cm, and a mass of 85,000 g. What is it's density?
wolverine [178]

Answer:

The answer is D.

Explanation:

Volume (V) = l x w x h

V = 4 x 5 x 1.2

V = 20 x 1.2

V = 24

Density = Mass/Volume  or D = M/V  

D = 85,000/24

D = 3541.66666666

220 mL of oxygen gas was collected over water. The total pressure of oxygen plus water vapor was 745.8 mmHg at 25.0°C. What is t
alukav5142 [94]

The pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg

<h3>Pressure of gas collected over water</h3>

The total pressure of a gas collected over water is given by P = P' + p where

  • P = pressure of oxygen gas and
  • p = vapour pressure of water at 25 °C = 25 mmHg

Making P' subject of the formula, we have

P' = P - p

Since the total pressure of oxygen plus water vapor is P = 745.8 mmHg, substituting the values of the variables into the equation, we have

P' = P - p

P' = 745.8 mmHg - 25 mmHg

P' = 720.8 mmHg

So, the pressure, in mmHg, exerted by only the oxygen gas is 720.8 mmHg
