<span>The equation for the dissociation of acetic acid is:
CH3CO2H(aq) + H2O(l) <---> H3O+(aq) + CH3CO2-(aq)
pH = 0.5(4.74 - lg(0.5)) = 2.52
so
[H^+] = 3.02*10^-3 M = 3.02 mM</span>
Answer:
Magnesium, Carbon and Oxygen.
Explanation:
We can directly solve
this problem using the wavelength formula which is:
wavelength = speed of
light / frequency
We know from the given
that 99.30 FM = 99.30 MHz, therefore:
wavelength =
(2.99*10^8 m/s) / (99.30*10^6 Hz) <span>
<span>wavelength = 3.011 meters</span></span>
