An acid is a molecule or ion capable of either donating a proton, known as a acid, or, capable of forming a covalent bond with an electron pair, The first category of acids are the proton donors.
I'm pretty sure the correct answer is C. they circle the nucleus in perfectly round orbits
Answer:-
A) 3.745
B) 2 x 10^-13 M
[H+]
pOH = 1.3
Explanation:-
A) From the question we see
The strength of HCl solution = 1.8 x 10^-4 M.
The M stands for molarity which is moles / Litre.
HCl is a monobasic acid. So the number of moles of Hydrogen ion H+ HCl can give is the same as the value of it’s strength in moles per litre.
The hydrogen ion concentration [H+] is therefore 1.8 x 10^-4.
The formula for pH is
pH = - log [ H+ ]
= - log [1.8 x 10^-4]
= 3.745
B) From the question we see
The strength of KOH = 0.05 M
The M stands for molarity which is moles / Litre.
KOH is a monoacidic base. So the number of moles of Hydroxyl ion OH- KOH can give is the same as the value of it’s strength in moles per litre.
The Hydroxyl ion concentration [OH-] is therefore 0.05
The relation between [OH-] and [H+] is
[H+] x [ OH-] = 10^-14
[H+] = 10^-14 / [OH-]
= 10^-14/ 0.05
= 2 x 10^-13 M
Using the relation between pH and [OH-]
pOH = - log [OH-]
= -log [0.05]
= 1.3
A policy of gradual reform rather than sudden change or revolution.
Answer:
Aqueous layer (1 M HCI)
Explanation:
First of us I want to remind you of the cliché in chemistry that like dissolves like. In solvent extraction, a mixture is dissolved in a system consisting of two immiscible solvents. One layer is organic while the other layer is aqueous.
Polar substances partition in the aqueous layer while nonpolar substances partition in the organic layer.
Since Copper sulfate is ionic, we will find it in the aqueous layer according to the old chemistry cliche.
