Answer:

B. 0.075 m (NH4)3PO4

Explanation:

Our strategy here is to recall the van´t Hoff factor, i, for the colligative properties of electrolyte solutions which appears as the consequence that electrolytes disociate completely in their solutions in water.

Thus in this problem we need to determine i and then realize the one with the lowest freezing point will have the biggest  i ( all the concentrations are equal) since

ΔTf = i m Kf

Substance  van´t Hoff factor

Li I                             2

(NH4)3PO4              4

NaIO4                       2

KCN                          2

KNO2                       2

The correct answer is B. 0.075 m (NH4)3PO4

Describe differences between conduction and convection give examples
nevsk [136]

Explanation:

Both conduction and convection are both forms of heat transfer from one place to another.

  • In conduction, there must be contact between two bodies for the process to take place but in convection, the matter moves to transfer heat.
  • Conduction mostly occurs in solid substances whereas convection occurs mostly in fluids.
  • Heat transfer in conduction is quite slow compared to convection which is much faster.

Example of conduction is heating of iron pot when cooking

Example of convection is the refrigerating system.

The flotation process used in metallurgy involves Multiple Choice the roasting of sulfides. separation of gangue from ore. elect
densk [106]

The flotation process used in metallurgy involves the separation of gangue from ore.

<h3>How does the flotation process work?</h3>

The various wettability qualities of a material's surface are the foundation of flotation operations. The basic principles of flotation are quite similar to those of a sink and float process, where the materials' relative densities to the medium in which they are deposited determine the basis of the separation.

<h3>What is the process of separating minerals from gangue known as?</h3>

Mineral processing, mineral dressing, or ore dressing are all terms for the process of separating minerals from gangue. It is an important and frequently necessary part of mining. Depending on the type of minerals used, the process may be difficult.
