<span>i think the answer should be 2KOH +H2SO4=K2SO4+2H20</span>
Answer: amount of substance n = cV = 2.0 mol/l x 0.25 l = 0.50 mol
Explanation:
Answer:
c = λ f
c is the speed of light, λ the wavelength in meters, and f equals the frequency in cycles per second.
Explanation:
The standard cell potential is obtained from the equation of the reaction.
<h3>What is the standard cell potential?</h3>
The standard cell potential is obtained from the equation of the reaction. Now we have the overall cell equation as from the half reactions as;
Oxidation half reaction;
Al(s) --->Al³+ (aq) + 3 e
Reduction half equation;
Cu²+ (aq) + 2 e →→ Cu(s)
Standard cell potential Eºcell = 0.34V - (-1.66 V) = 2 V
Now;
ΔG = -nFEcell
ΔG = -(2 * 6 * 96500 * 2)
ΔG = -2316kJ
E = 2 - 0.0592/6 log [0.0025]/[3.5 M]
E = 2 + 0.031
E = 2.031 V
