Front

Calculate the partial pressure of nitrogen gas in a mixture with 35% nitrogen and a total pressure of 4.5 atm.

Back

@@P_A = 0.35 \times 4.5 = 1.575 \text{ atm} \approx 1.6 \text{ atm}$$.

Front

If the partial pressures of argon, hydrogen, and nitrogen are 0.25 atm, 0.59 atm, and 1.35 atm, what is the total pressure?

Back

@@P_{total} = 0.25 + 0.59 + 1.35 = 2.19 \text{ atm}$$.

What separation technique is used to separate two liquids with different boiling points?

Back

The separation technique used to separate two liquids with different boiling points is called distillation.

Front

What is distillation?

Back

Distillation is a separation technique that involves heating a liquid to create vapor and then cooling the vapor to create a liquid, effectively separating components based on their boiling points.

Front

What is filtration?

Back

Filtration is a separation technique that uses a barrier (filter) to separate solid particles from liquids or gases.
