Answer:
101
Explanation:
Provided that
And,
Now we expect the same
{S} (0.1mM)
This determines that generates a higher rate of product formation as compared to the
So we can easily calculate the for either of or as we know that Tube 1 is and tube 2 is
As we know that
As the rates do not include any kind of units so we do not consider the units for
Now the calculation is
= 100.5
≈ 101
Answer:
Models aren't always 100% accurate. The world is ever-changing and so is everything in it. There is no sure way to know that your model is accurate all the time. Also, models aren't always easy to read. Some people struggle to read models, therefore models cannot be used by everyone.
Explanation:
These are just two of the limitations. Let me know if you need more. Happy to help : )
To answer this problem, we write first the stoichiometric equation. Thus we have,
Cu2S + O2 => 2Cu + SO2
Next, we check if the equation is balanced or not.
(left) (right)
2 Cu = 2 Cu
1 S = 1 S
2 O = 2 O
So the stoichiometric equation is balanced, let's proceed in solving the theoretical yield of Cu given 5 g of Cu2S.
First, we solve for Cu2S in moles,
5 g Cu2S x <u>1 mol Cu2S </u> = 0.0314 mol Cu2S
159.16 g Cu2s
Secondly, convert moles of Cu2S to moles Cu. Note for every mole of Cu2S we get 2 moles of Cu. Thus,
0.0314 mo Cu2S x <u> 2 mol Cu </u> = 0.0628 mole Cu<u>
</u> 1 mol Cu2S
Lastly, we convert mole Cu to g Cu via multiplying by Cu's MW.
0.0628 mole Cu x <u>63.546 g Cu </u> = 3.99 g Cu or 4 g Cu<u>
</u> 1 mole Cu
<em>ANSWER: 4 g Cu</em>
One is the plum pudding theory by Thomsons that theorized that positive and negative charges were randomly distributed in an atom. This was later discovered that the positive charge was located at the small nucleus center of the atoms and negative electrons on the outside.
Another is the aspect in Bohr model theory that electron orbit the nucleus like planets orbit the sun. Quantum mechanisms have come to disprove this and identify that electron orbit can only be predicted by probabilities and not in the certainty of their position around the nucleus of the atom. They randomly skip and hop (disappear and reappear) at positions around the nucleus.
