Answer:
I think ur answer would be refracted.
Explanation:
Answer:
6.517.
Explanation:
- It is known that for pure water: [H₃O⁺] = [OH⁻], so water is neutral.
<em>Kw = [H₃O⁺][OH⁻] = 9.25 x 10⁻¹⁴.</em>
∵ [H₃O⁺] = [OH⁻].
∴ [H₃O⁺]² = 9.25 x 10⁻¹⁴.
∴ [H₃O⁺] = √(9.25 x 10⁻¹⁴) = 3.041 x 10⁻⁷ M.
∵ pH = - log[H₃O⁺]
<em>∴ pH</em> = - log(3.041 x 10⁻⁷) = <em>6.517.</em>
Answer is <u>D</u> - homogeneous mixture has the same throughout a while a heterogeneous mixture is not a uniform throughout. Explanation: I hoped that helped.
Answer:
The (H30+) is 4,13x10-8
Explanation:
We use the formula
Kwater = (H30 +) x (OH-)
1.00e-14 = (H30 +) x 2.42e-7
(H30 +) = 1.00e-14 / 2.42e-7 = 4.13e-8M
Answer:
e. adiabatic process
Explanation:
Adiabatic process -
In the thermodynamic system , an adiabatic process is the one which involves no transfer of mass or heat of the substance , is referred to adiabatic process.
In this process , the temperature need not be constant ,
But only the heat is transferred into or out of the system .
Hence, from the given information of the question,.
The correct option is e. adiabatic process .
