Answer:
The concentration of the murexide solution is 0.0000745 M
Explanation:
From Beer-Lambert's law,
A = εlc
A = Absorbance = 28.65% = 0.2865
ε = molar absorptivity = 3847 M/cm
l = path length = 1cm
c = concentration in mol/L = ?
c = A/εl = 0.2865/(3847×1) = 0.0000745 mol/L
Hope this Helps!
I believe <span>Na2SO3 is the solution to the problem.</span>
Cl2 is nonpolar so it has to be only London dispersion force (LDF)
If this is a true of false question, note that it's false. Unsaturating the color, meaning giving it a lower amount up to zero, can cause gray tones - especially when it comes to pictures when editing it. High color saturation can make the color tone very vivid.
Q = 5637 J
C =4.814 J/KgºC
Temperature : 45.5ºC - 20.9º C = 24.6ºC
Q = m x C x T
5637 = m x 4.814 x 24.6
5637 = m x 118.4244
m = 5637 / 118.4244
m = 47.60 g
hope this helps!
