Answer:
b
Explanation:
orbital overlap electron densities.
Explanation:
Molar mass of
= 39.1 + 35.5 + 3(16.0) = 122.6 g
Molar mass of KCl = 39.1 + 35.5 = 74.6 g
Molar mass of
= 32.0 g
According to the equation, 2 moles of
reacts to give 3 moles of oxygen.
Therefore, 2 (122.6) = 245.2 g of
will give 3 (32.0) = 96.0 g of oxygen. Thus, 245.2 g of
gives 96.0 g of oxygen.
(a) Calculate the amount of oxygen given by 2.72 g of
as follows.
of
(b) Calculate the amount of oxygen given by 0.361 g of
as follows.
of
c) Calculate the amount of oxygen given by 83.6 kg
as follows.
of ![O_{2}](https://tex.z-dn.net/?f=O_%7B2%7D)
Convert kg into grams as follows.
= 32731 g of ![O_{2}](https://tex.z-dn.net/?f=O_%7B2%7D)
(d) Calculate the amount of oxygen given by 22.5 mg of
as follows.
![\frac {96g}{245.2g} \times 22.5 mg = 8.79 mg](https://tex.z-dn.net/?f=%5Cfrac%20%7B96g%7D%7B245.2g%7D%20%5Ctimes%2022.5%20mg%20%3D%208.79%20mg)
Convert mg into grams as follows.
of ![O_{2}](https://tex.z-dn.net/?f=O_%7B2%7D)
Answer: Quantitative data
Explanation:
Answer:
I think the answer would be b, sorry if I'm wrong(EDIT: ITS ACTUALLY AAAAA)
Answer:
54.99% yield
Explanation:
percent yield is just the amount you obtained over the amount expected times 100%.
(experimental value/theoretical value) x 100%
= (107.9 g/196.2 g) x 100%
=54.99% yield
