Answer: It is a basic solution with pH =8.51
Explanation:
We were given that hydroxide ion concentration [OH-] as 3.26 x 10-6 M
But We know thar
[OH-] [H+] = 1 × 10^-14
To get the Hydrogen ion [H+] concentration, we have that
[H+] = 1 × 10^-14 M/[OH-]
= 1 × 10^-14 M/3.26 x 10-6 M
= 3.067 x 10^-9 M
But, pH = - log [H+]
Therefore,
pH = - log (3.067 x 10^-9)
pH=8.51
when pH > 7, The solution is basic, therefore a solution with pH =8.51 is basic.
Answer:
helps in photosynthesis
Explanation:
when there is the presence of light the photosynthesis is dine
Answer:
= 3.7moles
Explanation:
I mole = 6.022 × 10²³ molecules
I molecule = 1 ➗ 6.022 × 10²³ moles
2.22 ×10‘’ 24molecules = (2.22×10‘’ 24) ÷6.022 × 10²³ moles
Number of moles = 2.22/6.022 × 10" 24-23
Number of moles = 0.37 × 10
Number of moles = 3.7moles

Answer:
Liquid helium
Explanation:
Liquid helium is known to be the coldest element in the world.
It has a ridiculous boiling point of -452 degrees
It is considered the only element on earth that does not freeze to become solid. normally, it is usually in a form of cryogenic fluid or superfluid.
Hence, the coldest element is known as LIQUID HELIUM
