The answer is most likely that the answer is B. Because Space is a dangerous place in which you need certain things to explore it. If you want to go to to Jupiter, for example you need lots of Oxygen, fuel, a good rocket, willing people and many more things, but there is a way technology can skip all that. the technology we have now is not capable of doing that though.

g .For each of the following disubstituted cyclohexanes, indicate whether the substituents in the two chair conformations would
Kryger [21]

Answer:

a) Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position

b) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

c) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

d) Both chairs have one of its substituents in an axial position and the other in an equatorial position

e) Both chairs have one of its substituents in an axial position and the other in an equatorial position

(f) One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

Explanation:

Determine what the substituents would be

a) Cis-1,2-  : Both chairs conformers have one of its substituents in an axial position and the other in an equatorial position

b) Trans-1,2- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

c) Cis-1,3- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

d) Trans-1,3- : Both chairs have one of its substituents in an axial position and the other in an equatorial position

e) Cis-1,4- : Both chairs have one of its substituents in an axial position and the other in an equatorial position

(f) Trans-1,4- : One chair conformer has both its substituents in an axial position while the other chair has its substituents in an equatorial position

How many atoms are there in 0.32g of copper
aivan3 [116]

The number   of atoms that are in 0.32 g  of  copper  are

 3.01 x10^21  atoms


        <u><em>calculation</em></u>

<u><em>    </em></u>Step  1: find the number of moles  of Copper

       moles =  mass/molar  mass

      =  0.32  g /63.5  g/mol=0.005  moles

 Step  2:  use the Avogadro's  constant  to determine  the  number of  atom                

             in  0.005 moles of Cu

 that is   according to  Avogadro's  law   1 mole =6.02 x10^23 atoms

                                                                    0.005 moles=?  atoms

          by cross   multiplication

  =  (0.005  moles  x 6.02 x10^23 atoms) /  1 mole= 3.01 x10 ^21 atoms
