What chemical reaction??? Very vague
The anwer roght here is the last one d. 0.0556 mol. The next procedure says why this is right:
<span>3.35 x 10^22 atoms x (1 mol / 6.02 x 10^23 atoms) = 0.0556 mol
</span>
I hope this can help you greatly
Answer: You probably know it now So um have great day
Explanation:
Answer:
Activation energy for the reaction is 39029J/mol
Explanation:
Arrhenius equation is an useful equation that relates rate of reaction at two different temperatures as follows:
<em>Where K₁ and K₂ are rate of reaction, Ea is activation energy and R is gas constant (8.314J/molK</em>
If the reaction at 400K is 50 times more faster than at 300K:
K₂/K₁ = 50 where T₂ = 400K and T₁ = 300K:
Ea = 39029 J/mol
<h3>Activation energy for the reaction is 39029J/mol</h3>
Answer:
3.5 mole of carbon
Explanation:
The atomic mass of carbon is 12.011 grams per mole.
That means, every mole of carbon atoms has a mass of 12.011 grams.
If you have 42.035 grams of carbon atoms, then every 12.011 grams of those carbon atoms, is 1 mole of carbon atoms...
You can solve this using unit conversion:
# mole carbon atoms = 42.035 grams C x (1 mole C / 12.011 g C) = 3.5 mole C
