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.

polet [3.4K]

Answer:

according to my reading

use own words

Explanation:

Salts are combinations of acids and bases. The cation comes from a base and the anion from an acid. Therefore, to make KNO3 we react KOH and HNO3. See how that is done? We write K and add OH to make KOH. We take NO3 and add H to make HNO3.

Determine the temperature change when 150. G block of gold is supplied with 1.00 • 10 ^3 J of heat
IceJOKER [234]

Answer:

∇T = 51.68°C

Explanation:

Mass = 150g

Heat Energy (Q) = 1.0*10³J

Change in temperature ∇T = ?

Q = mc∇T

Q = heat energy

M = mass

C = specific heat capacity of the gold = 0.129j/g°C

∇T = change in temperature

Q = Mc∇T

1.0*10³ = 150 * 0.129 * ∇T

1000 = 19.35∇T

Solve for ∇T

∇T = 1000 / 19.35

∇T = 51.679°C = 51.68°C

The change in temperature of gold was 51.68°C
