Answer:
Ka =
Explanation:
Initial concentration of weak acid =
pH = 6.87
HA dissociated as:
(0.00045 - x) x x
[HA] at equilibrium = (0.00045 - x) M
x =
0.000000135 <<< 0.00045
<u>Answer:</u>
3.67 moles
<u>Step-by-step explanation:</u>
We need to find out the number of moles present in 350 grams of a compound.
Molar mass of = 24.305
Molar mass of = 35.453
So, one mole of = 24.305 + (35.453 * 2) = 95.211g
1 Mole in 1 molecule of =
Therefore, number of moles in 350 grams of compound = 0.0105 * 350
= 3.67 moles
Power is energy divided by time and it’s unit is watta(W)
Products develop much faster than regular reactants
