Answer:
Solubility is 1.265g/L
Explanation:
According to Henry's law which states that the solubility of a gas in liquid is directly proportional to the pressure of the gas above the solution.
Sg1 / P1 = Sg2/ P2,
where Sg is the gas solubility, P is the gas pressure.
Sg1 = 0.22
P1 = 20kPA
P2 = 115kPA
Sg2 =?
Sg2 = Sg1 P2 / P1
Sg2 = 0.22 * 115*10^3 / 20*10^3
Sg2 = 25.3*10^3 / 20*10^3
Sg2 = 1.265g/L
the solubility of the gas in water at the new pressure is 1.265g/L
Answer:
Oxidation states are used in chemistry solutions. It is a bond in which electron transfers easily from one nucleus to another nucleus.
Explanation:
- Oxidation-reduction reactions have some rules.
- The oxidation state is 0 at an uncombined bond.
- The bond of oxidation reduction is +1 in alkeli metal.
- The bond in two metal is +2
- The oxidation reduction state at helogens is -1. It does not happened always.
- The oxygen bond in oxidation and reduction is -2.
- The sum of the oxidation state is equal to the compound charges.
- In this process the changes occur for any elements. Redox could be occur. Its oxidized and reduction reaction can be seen in this process.
Answer:
read a lot and understand what you read
do practicals
My educated guess should be the 3rd one
