Because the elements in group 7A are good at forming salts, the are called HALOGENS; the word 'halogen' mean SALT FORMERS. The halogens refers to the five non metallic elements that are found in group 7A, these are chlorine, bromine, iodine, fluorine and astatine. Each of these elements has seven electrons in their outermost shell and will readily react with metals to form ionic compounds. They all have oxidation number of -1.

A gaseous fossil fuel produced from organic matter that is used to heat homes and cook
Nostrana [21]

Answer:

Natural gas

Explanation:

Natural gas is a gaseous fossil fuel produced from organic matter that is used to heat homes and cook food.

Natural gas is one of the most volatile part of hydrocarbons that exist together with fossil fuel.

  • In a reservoir, natural gas is usually on top of the fossil fuel reserve.
  • It can also be distilled from crude oil as they rises up on top of the column first due to their low boiling point
  • The gas mixture is made up light hydrocarbons from methane to hexane.

What is the solubility of argon (in units of grams per liter) in water at 25 °C, when the Ar gas over the solution has a partial
beks73 [17]

Answer:

0.02405 g/L is the solubility of argon  in water at 25 °C.

Explanation:

Henry's law states that the amount of gas dissolved or molar solubility of gas is directly proportional to the partial pressure of the liquid.

To calculate the molar solubility, we use the equation given by Henry's law, which is:

C_{Ar}=K_H\times p_{gas}

where,

K_H = Henry's constant = 1.40\times 10^{-3}mol/L.atm

p_{Ar} = partial pressure of carbonated drink = 0.51atm

Putting values in above equation, we get:

C_{Ar}=1.40\times 10^{-3}mol/L.atm\times 0.430 atm\\\\C_{Ar}=6.02\times 10^{-4}mol/L

Molar mass of argon = 39.95 g/mol

Solubility of the argon gas :

6.02\times 10^{-4}mol/L\times 39.95 g/mol=0.02405 g/L

0.02405 g/L is the solubility of argon  in water at 25 °C.
