Answer:

6.5 L

Explanation:

Given: 0.80 mol in 4.5 L

Find: x liters containing (0.80 mol + 0.35 mol)

Solve: 0.80 mol/4.5 L = (0.80 mol + 0.35 mol)/ x

0.80 mol/ 4.5 L = (1.15 mol) /x

x = (1.15 mol)(4.5L)/(0.80 mol)

x = 6.47 L = 6.5 L

How many mols of a 3M NaOH solution are in 1L of the solution?
Alex

To calculate this, we need the Molarity formula. This formula tell us that Molarity, which is a concentration unit, is equal to the number of moles divided by the volume. In this question we already have the Molarity and the Volume, so let's build our equation:

C = n/V (You can see Molarity with the letter "C" because it means concentration)

3 = n/1

n = 1 * 3

n = 3 moles of NaOH

When Niels Bohr refined the model of an atom,what new idea did he include?
pshichka [43]

Answer:

Niels Bohr, refined the model of an atom by proposing a quantized shell structure atomic model in order to describe how the electrons are able to maintain stable orbits around the nucleus

Based on the predictions of classical mechanics the electron motion of the Rutherford model was unstable as the electrons where expected to have lost some energy during motion and thus having to come rest in the nucleus

According to the modification by Neils Bohr in 1913, electrons move in  shells or orbits of fixed energy and emission of electromagnetic radiation takes place only when electrons changes the orbit in which they move

If scientists had tried to repeat thomosons experiment and found that they could not would thomosons cocnclusion still have been
lesantik [10]

Answer:

No

Explanation:

The conclusions from Thomoson's claims would be invalid if his experiment could not be replicated.

<em>One of the attributes of a valid experiment in science is replication. That is, an experiment must be repeatable with similar outcomes under similar conditions as the original experiment when independently performed by another scientist. Once an experiment cannot be replicated, the outcomes of such an experiment become invalid in science.</em>

Hence, <u>Thomoson's conclusion would be invalid if his experiment could not be replicated. </u>
