Identify the solute and solvent in a solution made from 15 mL of oxygen and 5 mL of helium.
Marina CMI [18]

Answer:

Oxygen is solvent and Helium is solute.

Explanation:

Helium is a complety inert gas which do not react with other compounds whereas, oxygen can take part in chemical reaction with many compounds.

  • if we mix 15 mL of oxygen and 5mL of helium then the oxygen is the solvent and helium is solute.
  • In a mixture the compound with the greater volume is solvent and the compound with lwss volume is solute.
  • in this case, oxygen has greater volume than that of helium so oxygen is solute and helium is solvent here.

Which reverses the flow of current through an electric motor?
kirill [66]

Answer:

D

Commutator is the answer

Explanation:

The commutator systematically converts the current direction between the rotor and the outer circuit. As the shaft revolves, the commutator converts the course of current in a winding. For a separate armature winding, when a cylinder has reached one-half perfect turn, the winding is now attached so that current passes through it in the reverse of the original direction.
