What are the distinguishing features of each extraction process: pyrometallurgy, electrometallurgy, and hydrometallurgy? Explain
Tatiana [17]
<h3>1.Pyrometallurgy</h3>
  • This techniques involves the high temperature at which the Chemical reactions took place between the gases and solids.
  • Pyrometallurgy involves calcination, Roasting and smelting process.

 

<h3>  2.Electrometallurgy</h3>
  • This technique involves the metallurgy operations that took place in electrolytic cell.
  • Electro- winning and Electro-refining are some of the electrometallurgy process

<h3>   3. Hydrometallurgy</h3>
  • Reactions involves aqueous solutions to extract metal, use this technique.
  • Hydrometallurgy involves precipitation , distillation , adsorption and solid extraction operations.

Now,

Type of metallurgy are used in the production of Fe is Roasting and Smelting.

<h3>What is Roasting?</h3>
  • Ore is heated strongly with other substances, usually with Oxygen.
  • Process temperature is below the melting point.
  • Some of Impurities is removed as volatile substance.

In this reaction,

 FeO changes to Fe₂O₃ to prevent the loss of iron during smelting.

4FeO +O₂→ Fe₂O₃.

Now,

<h3>   What is Smelting?</h3>
  • The oxides of less electropositive metals like Pb, Zn, Fe, Sn, etc.
  • These are reduced by strongly heating with coal or coke.
  • Reduction of the oxide with Carbon at high temperature is known as Smelting.

Thus from the above conclusion we can say that , metallurgy are used in the production of Fe is Roasting and Smelting.

A student conducts an experiment to see how music affects plant growth. The student obtains four identical plants. Each one is p
motikmotik

The simplest and most helpful visual aid for this experiment would be if the student sets rulers of some sort or maybe pieces of wood that are properly marked with certain measuring unite. If they are set right next to each plant, the student will be able to monitor constantly how are the plants growing, and the smaller the measuring unites the better, as the student will be able to monitor the situation in higher detail.

Over time, the plants will most surely develop differently, so the student will have it easier to notice the changes. Considering that it is an experiment in question, the student should use proper measurements and to be able to have detailed numbers for it.

What variable represents specific heat in the equation q = mct?
Nata [24]

The "c" represents in specific heat in this question.


Q is the total energy, m is the mass, c is the specific heat capacity, and t is the temperature change. This equation is the equation for calculating about the total energy given out of absorbed when a temperature of a substance changes.


For example, if we want to know how much heat is absorbed by 1 kg of water for it to rise by 10 degrees, we can calculate by using the specific heat of water, which is around 4200 J kg-1 °C-1. So the total heat absorbed would be 1 x 4200 x 10 = 42000 J.

How many number of orbitals are in Potassium (K)?<br><br> 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1
Doss [256]

Explanation:

Each orbital can only carry at most 2 electrons wih opposite spins.

The first 3 shells are fully filled, giving 9 orbitals.

There is an extra electron in 4s, which gives another orbital. (even though it is not filled yet)

Hence there are 10 orbitals.
