Answer:
Explanation:
Dipole moment = charge x separation of charges
= (2 x 1.6 x 10⁻¹⁹ ) x ( 140 x 10⁻¹² ) coulomb-metre
= 448 x 10⁻³¹coulomb-metre
1 debye = 3.33 x 10⁻³⁰coulomb-metre
Dipole moment in debye = 448 x10⁻³¹ / 3.33 x 10⁻³⁰debye
= 448 x10⁻³¹ / 33.3 x 10⁻³¹
= 13.45 debye
=
Answer:
D. Evaporating, condensing, collecting
Explanation:
The mixture is first heated so that the liquid needed to be collected can be evaporated into gas. Then, the gas is condensed back to liquid in a condenser. (usually the condenser is supplied with cold running water so speed up the condensation). Then, the liquid is collected after being condensed, in an apparatus such as a conical flask or a water bath.
Vale verga no se what grade tho ?
