Answer:
C. Scientists accepted the model at first but later rejected it.
Explanation:
Scientists accepted the model at first because it explained the hydrogen emission spectrum.
However, with the development of quantum mechanics, scientists had to modify the model (not reject it).
Electrons still had specific energies, but they no longer travelled in fixed orbits.
Instead, electrons had a probability of being found in a given region of space.
The correct answer is c.
answer b is incorrect <span />
Answer:
Oxygen gas would be converted into solid oxygen by decreasing the temprature with the increase in preassure. It will bring its molecules together, which would result in the formation of solid oxygen
The answer I believe is 3.340kj.
The mole ratio can be seen below and the volume of each precipitate is 60 mL.
A mole ratio refers to a conversion factor that compares the quantities of two chemicals in moles in a chemical laboratory experiment.
<u>Mole ratio For 1:</u>
- = 10 mL : 50 mL
- = 1 : 5 mL
<u>Mole ratio For 2:</u>
<u>Mole ratio For 3:</u>
<u>Mole ratio For 4:</u>
<u>Mole ratio For 5:</u>
<u>Mole ratio For 6:</u>
<u>Mole ratio For 7:</u>
Since the parameters from the left side of the diagram are not shown, we will assume that the volumes for each precipitate are the addition of both volumes in each column.
By doing so, we have:
1.
2.
3.
4.
5.
6.
7.
