Answer:
= 4.37*10^-9 M
Explanation:
We know that;
pH + pOH = 14
Therefore;
pH = 14 - pOH
Which means; pH = 14 - 5.64
= 8.36
But;
pH = -log[H3O+]
Thus;
8.36 = -log[H3O+]
[H3O+] = 10^(-8.36)
= 4.37*10^-9 M
He proposed that energy levels of electrons are discrete and that the electrons revolve in stable orbits around the atomic nucleus but can jump from one energy level (or orbit) to another.
Answer:
The bronsted- Lowry acid is H₂PO₄⁻
Explanation:
Bronsted-Lowry acid donates a proton (H⁺)
H₂PO₄⁻ + OH⁻ → HPO₄²⁻ + H₂O
In the reaction above, H₂PO₄⁻ is donating the proton to OH⁻ resulting in H₂O and the deprotonated species. This makes it a bronsted-Lowry acid.
The sun heats up the air at different rates. Weather is caused by uneven heating
