<span>The Atomic Model was something that was first developed by Neils Bohr. Several years later, Schrodinger took Bohr's basis of a theory and developed it into something larger. So as we can see, theories are a bit like puzzles. When first starting out, one person develops something, or has an idea on something. Others trying to either prove or disprove the original findings, will then test things in a new way, revealing more and more of the puzzle. As the puzzle becomes more and more clear, there is more and more that is revealed. Eventually, we get to a point where we have almost the entire picture, however we are still missing a few key pieces that complete the puzzle. We can see the big picture, but you can not exactly prove out what exactly the details are. This is how scientists such as Bohr and Schrodinger use each others research to build and refine theories. Eventually, we reach a point where we are only missing maybe one or two pieces, and at that point, a theory transitions into almost fact, such as evolution.</span>

Answer the following questions.
maw [93]

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>

  • 15 mL : 45 mL
  • = 1 : 3 mL

<u>Mole ratio For 3:</u>

  • 20 mL : 40 mL
  • 1 : 2 mL

<u>Mole ratio For 4:</u>

  • 30 mL : 30 mL
  • 1 mL : 1 mL

<u>Mole ratio For 5:</u>

  • 40 mL : 20 mL
  • 2 : 1 mL

<u>Mole ratio For 6:</u>

  • 45 mL : 15 mL
  • 3 : 1 mL

<u>Mole ratio For 7:</u>

  • 50 mL : 10 mL
  • 5 : 1 mL

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.

  • (10 +50) mL = 60 mL

2.

  • (15 + 45) mL = 60 mL

3.

  • (20 + 40)mL = 60 mL

4.

  • (30 + 30) mL = 60 mL

5.

  • (40 + 20)mL = 60 mL

6.

  • (45 + 15) mL = 60 mL

7.

  • (50 + 10)mL = 60 mL
