Explain the difference between actual and theoretical yield

1 answer:

4 0

The major difference between the 2, is that actual yield is the amount or quantity of something, some substance and or product that you actually obtain upon working on the experiment, and or running a reaction. The theoretical yield, is the supposed amount and or quantity of product that you should obtain assuming that the reaction occurred perfectly and all of the reactants have been converted to products.
Usually the actual yield would be less than that of the theoretical yield, indicating that a chemical reaction and or process will never produce the complete or full amount of substance of what you supposed.

The highly reactive metals like sodium, potassium, magnesium, etc. Are extracted by the.

OlgaM077 [116]

Metals like sodium, potassium, magnesium, etc. are extracted by electrolysis of their chlorides in molten state.

These metals are not extracted by reduction of their oxides with carbon because:

Carbon has less affinity for oxygen than these metals

Carbon is a weaker reducing agent than these metals

These metals easily form oxides with oxygen, their oxides are very stable. Affinity to the oxygen is one the greatest of all elements.

Reducing agent is element or compound who loose electrons in chemical reaction. Sodium, potassium, calcium and magnesium are very strong reducing agents because they easily loose one or two valence electrons.

Electrolysis is a chemical methode that uses electric currents for chemical reactions.

Click on the Delta H changes sign whan a process is reversed button within the activity and analyze the relationship between the

OleMash [197]

Answer:

ΔH = - 44.0kJ

Explanation:

H2O(l)→H2O(g), ΔH =44.0kJ

In the reaction above, liquid water changes to gaseous water. This occurs through a process known as boiling. This process requires heat, hence the ΔH is positive.

If he reaction is reversed, we have;

H2O(g)→H2O(l)

In this reaction, gaseous water changes to liquid water. This process is known as condensation. The water vapor loses heat in this reaction. Hence ΔH would be negative but still have the same value.
