Answer:

el n = M/m. El nº de moles = m/M

Se utiliza la fórmula general de los gases: P*V = n*R*T

P = 760/760 = 1 atm

V = 0,5 L

n = masa de Cl2/masa molecular = masa de Cl2/70

R = 0,082

T = 273 + 20º C = 293 K

1*0,5 = masa de Cl2/70*0,082*293

0,5/0,082*293 = masa de Cl2/70

0,0208 = masa de Cl2/70

masa de Cl2 = 70*0,0208 = 1,46 g

kkurt [141]
<span>Pillow lavas have pillow-like structures and are formations that push lava on the surface of the earth underwater. Magma comes out of ocean ridges as pillow lava and forms a new oceanic crust, supporting sea floor spreading. The older crust gets pushed away from the ridge and pushes on to the continents, making them drift.</span>

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

The ions Cr3+ and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a
Kay [80]
For the compound formed to be neutral, the charge should be zero. This means that the positive charge should be equal to the negative charge. The balanced chemical reaction forming the neutral chromium oxide is shown below.
                              2Cr3+  + 3O2- --->  Cr2O3

Explain why thermal and electrical conductivity is so high with copper
lidiya [134]

Copper is formed of copper atoms, which are closely clustered together. If observed closely, one could witness the movement of electrons between the atoms of the copper. Each copper atom turns into a positive ion by losing one electron. Thus, copper is a lattice of positive copper ions with the movement of free electrons among them.  

Due to movement of electrons freely through the metal, they are also known as conduction electrons. The presence of these conduction electrons makes the copper a good conductor of electricity and heat.
