Alkenes undergo Electrophillic Addition Reactions. Electrophiles are added across double bond. In given reaction the H⁺ is first added across double bond as the double bond being denser in electron density act as a neucleophile. A carbocation formed depends upon the nature of Alkene, if alkene is symmetrical (as in our case) then positive charge can get any position, but in case of unsymmetrical alkene the positive charge will go to that carbon which is attached to more carbon atoms. Then the water molecule attacks the carbocation and forms alcohol.

Gold forms a substitutional solid solution with silver. Calculate the number of gold atoms per cubic centimeter (in atoms/cm3) f
Leokris [45]

Answer:

Gold: 1.1 x 10²² atoms/cm³

Silver: 4.8 x 10²² atoms/cm³

Explanation:

100 g of the alloy will have 29 g of Au and 71 g of Ag.

19.32 g Au ____ 1 cm³

29 g Au ______  x

x = 1.5 cm³

10.49 g Ag ____ 1 cm³

71 g Ag _______   y

y = 6.8 cm³

The total volume of 100g of the alloy is x+y = 8.3 cm³.

Gold:

196.97 g Au____ 6.022 x 10²³ atoms Au

29 g Au _______ w

w = 8.9 x 10²² atoms Au

8.9 x 10²² atoms Au ____ 8.3 cm³

           A                    ____ 1 cm³

A = 1.1 x 10²² atoms Au

Silver:

107.87 g Ag____ 6.022 x 10²³ atoms Ag

71 g Ag _______ w

w = 4.0 x 10²³ atoms Ag

4.0 x 10²³ atoms Ag ____ 8.3 cm³

          B                    ____ 1 cm³

B = 4.8 x 10²² atoms Ag

What is the percent composition of chlorine in C2H2Cl2? Solve to the correct number of significant figures.
oksian1 [2.3K]

Answer:

\%Cl=73.13\%

Explanation:

Hello.

In this case, we can compute the percent composition of chlorine as shown below:

\%Cl=\frac{2*m_{Cl}}{M_{C_2H_2Cl_2}}

Whereas the atomic mass of chlorine is 35.45 g/mol and the molar mass of C₂H₂Cl₂ is 96.95 g/mol, thus, the percent composition turns out:

\%Cl=\frac{2*35.45g/mol}{96.95g/mol}*100\%\\\\\%Cl=73.13\%

Best regards.
