Answer:
Ka2 values should be used in obtaining pKa2 in the Henderson–Hasselbalch equation
Explanation:
During first dissociation from H3PO4 to H2PO4-, ka1 will be used, and from H2PO4-to HPO4-, ka2 values will be used, hence a buffer solution containing H2PO4-and HPO4-will use ka2 in obtaining pKa2 in the Henderson–Hasselbalch equation.
Answer:
a) H2S:SO2 = 2:2 and O2:H2O = 3:2
Explanation:
⇒ H2S:SO2 = 2 mol H2S / 2 mol SO2 ≡ 2 : 2
⇒ O2:H2O = 3 mol O2 / 2 mol H2O ≡ 3 : 2
Answer:
it would be in the keyhole probably
Explanation:
Because you would have to put the screwdriver inside to try and break the lock
That is true because the warm air goes up and the cold air comes down
Explanation:
10.0mg / 1.25mg = 8
1/8 of the original mass => 3 half-life phases
Hence it will take 25.0 min * 3 = 75.0min.
