Select the keyword or phrase that will best complete each sentence. law is a gas law that relates pressure and volume and states
kondor19780726 [428]

Answer:

Find answers below.

Explanation:

1. Boyle's law is a gas law that relates pressure and volume and states that for a fixed amount of gas at constant temperature, the pressure and volume of the gas are directly related.

Mathematically, Boyle's law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Where;

P1 and P2 represents the initial and final pressures respectively.

V1 and V2 represents the initial and final volumes respectively.

2. Charles law is a gas law that states that for a fixed amount of gas at constant pressure, the volume of the gas is propotional to its Kelvin temperature.

Mathematically, Charles is given by;

VT = K

\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}

Where;

V1 and V2 represents the initial and final volumes respectively.

T1 and T2 represents the initial and final temperatures respectively.

3. Dalton law is a law that states that the total pressure of a gas mixture is equal to the sum of the partial pressure of its component gases.

4. Avogadro's law is a gas law that states that the volume of a gas is directly proportional to the number of moles of present when the pressure and temperature are held constant.

5. Gay Lussac's law is a gas law that states for a fixed amount of gas at constant volume, the pressure of the gas is directly proportional to its Kelvin temperature.

Mathematically, Gay Lussac's law is given by;

PT = K

\frac{P1}{T1} = \frac{P2}{T2}

6. The combined gas law is a gas law that relates pressure, volume, and temperature.

7. The ideal gas law is the equation PV = nRT

Where;

P is the pressure.

V is the volume.

n is the number of moles of substance.

R is the ideal gas constant.

T is the temperature.

Explain why groups 14 and 15 are better representatives of mixed groups than groups 13 and 16
Brrunno [24]
<h3><u>Answer</u>;</h3>

Groups 14 and 15 each contain metals, nonmetals, and metalloids while Group 13 contains metals and a metalloid, and Group 16 contains metalloids and nonmetals.

<h3><u>Explanation;</u></h3>
  • Groups 13–16 of the periodic table contain one or more metalloids, in addition to metals, nonmetals, or both.
  • Unlike other groups of the periodic table, which contain elements in one class, groups 13–16 referred to as mixed groups contain elements in at least two different classes. In addition to metalloids, they also contain metals, nonmetals, or both.
  • <em><u>Group 14 also known as the carbon group contains carbon which is a non metal, silicon and germanium which are metalloids and tin and lead which are metals.</u></em>
  • <em><u>Group 15 also known as the Nitrogen group contains non metals such as oxygen, metalloid tellurium and a metal polonium.</u></em>
