How many moles of atoms are in 2.00 g of 13c?

Troyanec [42]

I think what '13C' means is the isotope of carbon with mass number of 13. Its mass is 13 amu. The unit amu is equivalent to g/mol. The average atomic mass of Carbon is actually 12. But since we are solving for this particular isotope, we use a molar mass of 13 g/mol.

2 g C-13 * 1 mol/13 g = 0.154 moles of C-13

REY [17]

Answer:

Explanation:

According to this. Let's analize the possible products a, b and c.

First, the problem states that we have 2 eq. of base, For this case, let's assume it's KOH. Now, As we are doing a reaction with base, means that this reaction can only take places under conditions of SN2 and E2, a fast reaction that is taking place in only 1 step.

With this in mind, let's analyze product a. This states that it has two sp hybridized carbon, in other words, a triple bond between two carbons. So the product is with no doubt, an alkyne.

Product b has only one sp hybridized carbon, which means that this carbon should cannot be an alkyne because we need two carbon atoms. The only way to have one atom of C sp hybridized, is with two double bonds, so product b would have to a alkene with two double bonds.

Product c do not have sp hybridized carbon, therefore, it only has two double bonds in two different Carbon atoms, so it's another alkene with two double bonds, but in two different atoms of carbon.

Picture attached show the product a, b and c. Hope this can help

How do optical telescopes work ?

inn [45]

They allow us to see further and are able to focus on light from distant object. This is done by refracting or reflecting the light using lenses or mirrors.

Why do we need to have common denominators when adding fractions?

jeyben [28]

So that we have the right answer once we do the addition
Say that I measure my self at 12 feet with one measuring stick, and go on with another measuring stick that tells me I'm 3 meters tall, if I added those, I would be at something like 15/46 or something like that. See that would be wrong. We would want the right denominator so that it could be easier and also correct.

What is a distinguishing feature about ionic bonds?

Sergeeva-Olga [200]

Answer:

Here:

Explanation:

So ionic bonds are formed due to electrostatic attraction. For example, in NaCl, Na gives an electron to Cl, getting Na+ and Cl- where + and - charges attract and form an ionic bond.
