What is the [h3o+] in a solution with a poh = 5.20?

Chemistry

Pepsi [2]3 years ago
7 0
POH scale is used to measure how alkaline a solution is
pOH can be calculated as follows
pOH = - log [OH⁻]
pOH is 5.20 and using this the pH can be calculated
pOH + pH = 14
pH = 14 - pOH 
pH = 14 - 5.20 = 8.80
pH scale is used to measure how acidic a solution is
pH = -log [H₃O⁺]
[H₃O⁺] = antilog (-8.80)
[H₃O⁺] = 1.6 x 10⁻⁹ M
answer is [H₃O⁺] = 1.6 x 10⁻⁹ M

Compare and contrast alpha beta and gamma radiation
Evgen [1.6K]
There are usually 3 topics used to compare types of radiation: 

Ionising ability
Penetrative power 
Range in air

Ionising ability
Alpha radiation has strong ionising ability, while beta only has moderate ionisation and gamma is very weakly ionising.

Penetrative power 
Alpha particles are weakly penetrating, stopped by paper, while beta particles have stronger penetrating ability, stopped by skin and gamma radiation is very strongly penetrating, stopped only by thick layers of lead.

Range in air
Alpha particles- range of only a few centimetres
Beta - range of up to one meter 
Gamma- infinite range in air.

Hope this helps:)

At what temp will a gas be at if you allow it to expand from an original 456 mL to 65°C to 3.4 L
alexira [117]
We use the gas law named Charle's law for the calculation of the second temperature. The law states that,
                                          V₁T₂ = V₂T₁
Substituting the known values,
                                (0.456 L)(65 + 273.15) = (3.4 L)(T₁)
                                             T₁ = 45.33 K

What does a chemist do​
Mama L [17]
A chemist (from Greek chēm (ía) alchemy; replacing chemist from Medieval Latin alchimista[1]) is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, reaction rates, and other chemical properties. The word 'chemist' is also used to address Pharmacists in Commonwealth English.
