Answer:
- <em>(B.) The pH of a buffer solution is determined by the ratio of the concentration of conjugate base to the concentration of strong acid.</em>
- <em>(C.) A buffer is generally made up of a weak acid and its conjugate base. </em>
- <em>(D.) The pH of a buffer solution does not change significantly when any amount of a strong acid is added.</em>
Explanation:
A buffer is solution which resists change in pH upon addition of either acids or bases.
The pH of a buffer is calculated by the ratio of the concentration of base to concentration of acid. The weak acid and conjugate base have a Ka similar to the pH desired.
The answer is
a symmetrical molecule.
Answer:
5
Explanation:
NH4OH
The subscript gives the info that there are 4 hydrogen atoms but there is another H in the formula so you add them up.
If I am correct the answer would be iron and nickel.
There are 30 inches in 2.5 just know that a foot is 12 inches so 12 times 2.5 is 30
