VashaNatasha [74]3 years ago
3 0

Answer:

Moles= 10.55*10^29ǜ.02*10^23

=1.75*10^6 moles

Moles= mass/molar mass

1.75*10^6=mass/ 183

Mass= 320*10^6 g

Determine if the bond between each pairs of atoms would be pure covalent, polar covalent, or ionic. n and se
Sveta_85 [38]

Types of Bonds can be predicted by calculating the difference in electronegativity.

If, Electronegativity difference is,

 

                Less than 0.4 then it is Non Polar Covalent Bond

                

                Between 0.4 and 1.7 then it is Polar Covalent Bond

            

                Greater than 1.7 then it is Ionic

 

For N and Se,

                    E.N of Nitrogen         =   3.04

                    E.N of Selenium        =   2.55

                                                   ________

                    E.N Difference             0.49          (Weakly Polar Covalent)


As you have not provided remaining pairs, so if you have any of them, follow the method as mentioned above.

1. There are how many mol of oxygen in 3.5 mol of caffeine.
inysia [295]

Answer:

7 mol

Explanation:

Caffeine molecular formula C8H10N4O2. It has 2 atoms of oxygen.

                          C8H10N4O2         - 2O

                           1 mol                        2 mol

                           3.5 mol                    x mol

x = 3.5*2/1 = 7 mol
