How many moles are in 1.93 x 10^24 atoms of gold

Chemistry

Anni [7]3 years ago
6 0

Answer:

We know that 1 mole equals to 6.02 x 10^23 atoms (which is Avogadro's number), so to get to atoms from moles, you would divide the atoms of gold by Avogadro's number

(1.93 x 10^24) / (6.02 x 10^23)

= 3.2 mol of gold (rounded)

Electrons are closer to the nucleus are in filled orbitals and are called core electrons. More energy which in nucleus called nuclear strOng energy to remove electron thars why its also a way harder too..

Four acids are analyzed and there KA values are determined which of the following values represents the strongest acid
Advocard [28]

x= the coefficients in front of the substance in the balanced chemical equation  

[H+]= the concentration of hydrogen ions  

[A-]= the concentration of the other ion that broke off from the H+  

[HA]= the un-disassociated acid concentration  

The higher the Ka value, the greater amount of disassociation of the reactants into products. As for acids, they will break down to form H+ ions. The more the H+ ions, the stronger acidity of the solution. Thus since A has the highest Ka value, that represents the strongest acid.  

You can determine the Ka value from a number of ways. If equilibrium concentrations are given of a certain acid solution, you can find the proportion of the concentration of ions to the concentration of the remaining HA molecules, using the equation above. Also, pH and KpH can be used in a number of ways. This gets more complicated and depends on the situation, and requires more advanced equations.


Hope this helped a little, its obviously not my best work
