Answer:
Explanation:
Remember that
To convert L to mL multiply by 1,000
we know that
Gina made 9,350 mL
She packed 1.8 L of the soup in her kids' lunches
She froze the rest of the soup
step 1
Convert L to mL
step 2
To find out how many milliliters of soup did Gina have left to freeze, subtract 1,800 mL from 9,350 mL
Answer
is: activation energy of this reaction is 212,01975 kJ/mol.<span>
Arrhenius equation: ln(k</span>₁/k₂) =
Ea/R (1/T₂ - 1/T₁).<span>
k</span>₁
= 0,000643 1/s.<span>
k</span>₂
= 0,00828 1/s.
T₁ = 622 K.
T₂ = 666 K.
R = 8,3145 J/Kmol.
<span>
1/T</span>₁ =
1/622 K = 0,0016 1/K.<span>
1/T</span>₂ =
1/666 K = 0,0015 1/K.<span>
ln(0,000643/0,00828) = Ea/8,3145 J/Kmol ·
(-0,0001 1/K).
-2,55 = Ea/8,3145 J/Kmol </span>· (-0,0001 1/K).<span>
Ea = 212019,75 J/mol = 212,01975 kJ/mol.</span>
A electrolytic* cell that electrolysis occurs
Ex. let say you wanted traces of graphene you would set up your usual electro-chemical exfoliation rig and the graphite you submerge would be your electrolytic cell.
