The characteristics which determines an element's reactivity are; Valence electrons and Electronegativity

As we know;

The reactivity of an element is it's ability to undergo a chemical reaction.

Chemical reactions occur as a result of the transfer of electrons between two atoms.

The electrons involved in chemical reactions are the Valence (outermost) electrons.

The electronegativity value of an element is a measure of its electron affinity, i.e how well it readily accepts or losses electrons.

Ultimately, the characteristics which determines an element's reactivity are; Valence electrons and Electronegativity

Which of the following should have the largest Henry's law constant (kH) in water?
Ostrovityanka [42]

Answer: Option (B) is the correct answer.

Explanation:

It is known that Henry's law is a relation between the concentration of a gas in a liquid (solubility) and the pressure it exerts on the surface of the liquid.

According to Henry's law, the pressure of a gas is directly proportional to the solubility of the gas in a liquid.

Henry's constant is represented by the symbol K_{H}. And, mathematically it is represented as follows.

                      P = K_{H}C  

where,      P = pressure and C = solubility

As the pressure for the given species is the same. Hence, the standard values of solubility of the given species is as follows.

               Gas           Solubility

                Ar          3.025 \times 10^{-5}

               CO         2.095 \times 10^{-5}

               Xe         10.519 \times 10^{-5}

            CH_{3}CH_{3}   4.556 \times 10^{-5}

              CO_{2}   8.21 \times 10^{-4}

As, Henry's constant is inversely proportional to the solubility. Hence, more is the value of solubility lesser will be the value of Henry's constant.

Thus, we can conclude that out of the given options CO have the largest Henry's law constant (K_{H}) in water.

The si unit used to measure the activity of a radioactive sample is called the
maks197457 [2]
How is the activity of a radioactive sample measured? In terms of the number of nuclear disintegrations per second. The Curie (Ci) is the unit used commonly, the Becquerel is the SI unit. The number of nuclear disintegrations that occurs in 1 second for 1 gram of radium, which is 3.7 x 10^10 disintegrations.
