Carbon is more electronegative
Answer:
omg
Explanation:
omg omg omg omg omg omg omg omg omg omg I can't either ehhhhhh
Mass of water = density x volume
Mass of water = 0.413 x 1
Mass of water = 0.413 g
Energy absorbed = mCpΔT
Energy = 0.413 x 4.184 x 76.5
Energy = 132.2 J
Using Planck's equation:
E = nhc/λ
132.2 = (n x 6.63 x 10⁻³⁴ x 3 x 10⁸) / (13.3 x 10⁻²)
n = 8.84 x 10²⁵ photons
Answer:
pKa = 4.89.
Explanation:
We can solve this problem by using the <em>Henderson-Hasselbach equation</em>, which states:
pH = pKa + log
In this case [A⁻] is the concentration of sodium benzoate and [HA] is the concentration of benzoic acid.
We <u>input the given data</u>:
4.63 = pKa + log
And <u>solve for pKa</u>:
pKa = 4.89
