Chemistry

I believe it would be the second one. Because it is asking how to prevent it before it happens so it would not be a or d and c would not be good because you do not want to smell chemicals.

Which of the following apply to diffusion. Select all that apply. Solids can diffuse in liquids. Liquids can diffuse in liquids.
e-lub [12.9K]

Correct answers are:

  • Solids can diffuse in liquids. Think of a sugar cube sitting at the bottom of a cup of tea.
  • Liquids can diffuse in liquids. Think of a drop of food colouring in water
  • It is the process of intermingling atoms from one substance into another.

The other answers are <em>incorrect</em> because:

  • Gas molecules are far apart and diffuse rapidly.  
  • A solid can diffuse into another solid. Pure lead can diffuse into gold, and pure gold can diffuse into lead.

Greeley [361]

Use Charles' Law: V1/T1 = V2/T2. We assume the pressure and mass of the helium is constant. The units for temperature must be in Kelvin to use this equation (x °C = x + 273.15 K).

We want to solve for the new volume after the temperature is increased from 25 °C (298.15 K) to 55 °C (328.15 K). Since the volume and temperature of a gas at a constant pressure are directly proportional to each other, we should expect the new volume of the balloon to be greater than the initial 45 L.

Rearranging Charles' Law to solve for V2, we get V2 = V1T2/T1.  

(45 L)(328.15 K)/(298.15 K) = 49.5 ≈ 50 L (if we're considering sig figs).
