Phyisical equlibiria deal with the equillibirium phenomena that does not involve any chemical change these are actually chemical changes or solubility this will look at both changes of pure substances as well as mixtures
The answer is A it's a basic because once you add another substance to a neutral it either becomes acidic or basic. this one becomes basic because the hydroxide ion concentrate increased.
Answer:
2 KOH → H₂O + K₂O
Explanation:
When KOH descomposes in potassium oxide, K₂O and water, H₂O.
The unbalanced equation is:
KOH → H₂O + K₂O
As you can see, 2 hydrogen, potassium and oxygen atoms are produced, to balance this equation we can write:
2 KOH → H₂O + K₂O
This is the balanced equation because 2 atoms of K, H and O are in reactants and products
Answer:
... Sorry I don't know the answer
Atomic number = protons
Protons = P Electrons = E P = E
Atomic mass = Neutrons + Protons
Atomic number = atomic mass = neutrons
P = E
AM - AN = N
Example:
Calcium = 20 Protons 20P = 20E
Atomic mass - atomic number = neutrons :)
