What is the relatioship between atomic numbers and ionic radii of the elements in Group 1? what is the relationship between atom

Sever21 [200]

As atomic number increases atomic radii also increase down group 1. ionisation energy down group 1 will also decrease because as atomic radii gets bigger there is less electrostatic force between nuclei and electrons so less energy needed to remove valence electron.

What else is produced when sodium carbonate decomposes? Na2CO3 Na2O +

andriy [413]

When a single compound breaks down into two or more compounds or elements in a chemical reaction then it is known as decomposition reaction.

The chemical symbol for sodium carbonate is $Na_2CO_3$ .

The decomposition of sodium carbonate is:

$Na_2CO_3\rightarrow Na_2O+ CO_2$

The decomposition of sodium bicarbonate, $Na_2CO_3$ will result in the formation of sodium oxide, $Na_2O$ and carbon dioxide, $CO_2$ .

Hence, carbon dioxide, $CO_2$ will produce with sodium oxide, $Na_2O$ on decomposition of $Na_2CO_3$ .

Draw a mechanism for the first step of the reaction between methyllithium (CH3Li) and acetone. Then answer the two multiple choi

pogonyaev

Answer:

See the attached image

Explanation:

The first step is the production of the carboanion in the $CH_3Li$ compound. We will get the negative charge on the methyl group and the positive charge in the Li atom.

Then the carboanion can attack the acetone. The double bond of the oxo group would delocalized upon the oxygen, generating a positive charge in the carbon that can be attacked by the carboanion formaiting a new C-C bond.

How do you find the molar mass of a hydrate

Darya [45]

If you mean hydrate as in MgSO4 · 7H2O, then simply find the molar mass of each element you see.

For the example above, that means you would add the molar mass (found on the periodic table) of Mg, then S, then 4(O), 14(H), and 7(O).

The results would be your molar mass for the hydrate.

I hope this is what you meant by your question!

16. The concentration of a solution of potassium hydroxide is determined by titration with nitric

____ [38]

Answer:

$M_{base}=0.709M$

Explanation:

Hello,

In this case, since the reaction between potassium hydroxide and nitric acid is:

$KOH+HNO_3\rightarrow KNO_3+H_2O$

We can see a 1:1 mole ratio between the acid and base, therefore, for the titration analysis, we find the following equality at the equivalence point:

$n_{acid}=n_{base}$

That in terms of molarities and volumes is:

$M_{acid}V_{acid}=M_{base}V_{base}$

Thus, solving the molarity of the base (KOH), we obtain:

$M_{base}=\frac{M_{acid}V_{acid}}{V_{base}} =\frac{0.498M*42.7mL}{30.0mL}\\ \\M_{base}=0.709M$

Regards.
