Answer:
for 1 Litre(1000 ml) of 1x TBE
10.8 g Tris
5.5 g Boric acid
4 ml 0.5 M EDTA (pH 8.0)
900 ml distilled water
Adjust volume to 1 Liter.
<u>so for 250 ml divide everything by 4</u>
2.7 g Tris
1.37 g Boric acid
1 ml 0.5 M EDTA (pH 8.0)
225 ml distilled water
Adjust volume to 250 Ml
The metric system is based on powers of 10 so it is much easier to convert units, often just by moving the decimal point.

Answer:
C. It shows you that the formation of water is a reversible reaction, which contains hydrogen and hydroxide ions.
Explanation:
The equation is
H₂O(ℓ) ⇌ H⁺(aq) + OH⁻(aq)
It also shows that water can behave as either an acid or a base, because it can produce both H⁺ and OH⁻ ions.
A and B are both wrong. Although the statements are correct, they don't say anything about acids and bases.
