Given:
0.607 mol of the weak acid
0.609 naa
2.00 liters of solution
The solution for finding the ph of a buffer:
[HA] = 0.607 / 2.00 = 0.3035 M
[A-]= 0.609/ 2.00 = 0.3045 M
pKa = 6.25
pH = 6.25 + log 0.3045/ 0.3035 = 6.25 is the ph buffer prepared.
Metallic bond is the electrostatic attraction between a positive ion and delocalised(free)electrons
Answer:
Glucose. C6H12O6
Explanation:
In aerobic respiration glucose generate ATP. Which are the source of energy.
Relative atomic mass of NaCl=23+35.5=58.5
2000kg / 58.5 = mass per relative atomic mass = 34.188
34.188 * atomic mass of Na, 34.188 * 23 = 786.325... = 790 kg (2s.f.)
Answer:
7.85% of Hydrogen in the sample.
Explanation:
51/650 = .07846 x 100= 7.846% (round up)
