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.

Solve 4x-8x=-3 I need help
koban [17]

4x − 8x= −3

Step 1: Simplify both sides of the equation.

4x−8x = −3

4x + −8x= −3

(4x + −8x) = −3 (Combine Like Terms)

−4x = −3

Step 2: Divide both sides by -4.

−4x / −4  

−3 - / −4

so your answer will be x=  3/4 .
