Answer:
1533.6 kg NO
Explanation:
The reaction that takes place is:
First we <u>convert the masses of ammonia (NH₃) and oxygen gas (O₂) into moles</u>, using<em> their respective molar masses</em>:
- NH₃ ⇒ 869 kg ÷ 17 kg/kmol = 51.12 kmol NH₃
- O₂ ⇒ 2480 kg ÷ 32 kg/kmol = 77.5 kmol O₂
77.5 kmol of O₂ would react completely with (77.5 kmol O₂ * ) 62 kmol of NH₃. There are not as many kmol of NH₃, so NH₃ is the limiting reactant.
Now we <u>calculate how many kmol of NO are produced</u>, using the <em>limiting reactant moles</em>:
- 51.12 kmol NH₃ * = 51.12 kmol NO
Finally we <u>convert kmol of NO to mass</u>, using its<em> molar mass</em>:
- 51.12 kmol NO * 30 kg/kmol = 1533.6 kg NO
Answer:
3.77 x 10^-11
Explanation:
So the equilibrium would be (0.725 - 0.00000523) ≈ 0.7249
Ka = [H+] x [CH3COO^-] / [CH3COOH]
Ka = [5.23 x 10^-11] x [5.23 x 10^-11] / 0.7249
Ka = 3.77 x 10^-11
Hope this helped : )
3.25 g H (1 H / 1.008 g H) = 3.22
19.36 g C (1 C / 12.01 g C) = 1.61
77.39 g O (1 O / 15.9994 g O) = 4.84
Take the smallest number calculated and divide the others by it.
1.61/1.61 = 1
C = 1.
3.22/1.61 = 2
H = 2
4.84/1.61 = 3
O = 3
=CH2O3
