Answer: Please see below for answers
Explanation: Matching appropriate labels , we have
1)3/4 of the way to second equivalence point of a diprotic acid/strong base titration-- pH=pka₂
equivalence point of a weak base/strong acid titration=pH<7
equivalence point of a strong acid/strong base titration= pH=7
equivalence point of a weak acid/strong base titration=pH>7
half-way to equivalence point of a weak acid/strong base titration pH =pka
where
pH gives the measure of the amount of concentration of hydrogen ions in an aqueous solution.
pKa is known as acid dissociation constant which explains the equilibrum at which a chemical species can give out or receive proton
pka₂ is the acid dissociation constant for the second ionization energy.
<span>Answer:
The total anion concentration = 6.0 + 2x12.0 + 3.0 = 33.0mEq/L</span>
Answer:
beryllium: 2 valence electrons
nitrogen: 5 valence electrons
oxygen: 6 valence electrons
fluorine: 7 valence electrons
magnesium: 2+ valence electrons
phosphorus: 5 valence electrons
sulfur: 6 valence electrons
chlorine: 7 valence electrons
Explanation:
Answer:
<h3>The answer is 43.89 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 57.5 g
density = 1.31 g/mL
We have
We have the final answer as
<h3>43.89 mL</h3>
Hope this helps you
water <span>t because washing with sulfuric acid wouldn't actually get any
of the acid off of you, same with oil, just soothe it momentarily and
stop burning of the skin by creating a barrier to the acid. If you wash
with soap
it will burn even more by activating some enzymes in the acid (depending
on kind of acid) so washing with water is most practical because it
gets all of the acid off immediately to stop more burns from occurring. I
would recommend washing with water and then pouring oil onto the burn,
to create a barrier. </span>
