Answer:
3.3765 Mol O2
Explanation:
There is no work for this problem
Answer: Balance, multiply, find ratio
Explanation:
Balance the equation to be able to multiply correctly and accurately, multiply, and this will give you the molar ratio
The balanced chemical reaction is :
Number of moles of Na, 
.
Now, from balance chemical reaction we can see that 1 mole of oxygen reacts with 4 moles of sodium.
So, number of moles of oxygen are :
So, amount of oxygen required is :
Therefore, 5.08 gram of oxygen will react with 14.6 gram of sodium.
Answer:
rise in temperature and the effect it has on our global weather patterns
Answer:
K(70°C) = 2213.376 s-1
Explanation:
balanced reaction:
- NO(g) + O3(g) → NO2(g) + O2(g)
∴ Ea = 63 KJ/mol
∴ A = 8.7 E12 s-1
∴ T = 70°C ≅ 343 K
Arrhenius eq:
∴ R = 8.314 E-3 KJ/K.mol
⇒ K(70°C) = (8.7 E12 s-1)e∧[-(63)/(8.314 E-3)(343)]
⇒ K(70°C) = (8.7 E12 s-1)*(2.5444 E-10)
⇒ K(70°C) = 2213.376 s-1
