Since Kw= [H⁺][OH⁻], and the concentration of both substances are the same, the equation is now Kw=[H⁺]²
So,
3.31x10⁻¹³ = [H⁺]²
Take the square root= 5.75x10⁻⁷
Then take the negative log to find the pH:
-log(5.75x10⁻⁷) = 6.25
Answer:
The answer is
<h2>324 K</h2>
Explanation:
To express a given temperature in degree Celsius to Kelvin simplify add 273 to the given value
That's
<h3>K = 273 + °C</h3>
where
K = Kelvin
°C = value in degree Celsius
From the question the value to be converted is 51°C
It's equivalent in Kelvin is
K = 273 + 51
We the final answer as
<h2>324 K</h2>

Strontium element has a mass number of 88 and contains 50 neutrons in the atom.
Given that;
Mass number of element X = 88
Number of Neutrons in element X = 50
we know the concept that Mass number is represent as total number of Neutrons and proton present in Nucleus
So, Mass number of element X = Number of Neutrons in element X + Number of Protons in element X
Thus, 88 = 50 + Number of Protons in element X
Number of Protons in element X = 38
As, Number of proton = Atomic number
So, Atomic number of element X = 38
Hence Unknown Element X is Strontium
