What is the difference between adequate and excessive in chemistry

Sufficient refers to the amount of good reaction, and excess refers to not only the complete reaction but also the remaining substances added.

The sufficient amount is just completely reflected, while the excess is left after the other reflections.

1. The amount is different. In a literal sense, the difference between the three can be milled, with a small amount indicating that the reagent has been replaced, a sufficient amount indicating that the reagent is sufficient, and an excess indicating that the reagent is left.

2. The number of products produced is different. A small amount of the reaction product is produced, and the reaction product can be synthesized in sufficient amounts and in excess amounts.

3. The degree of progress of the reaction is different. A small amount indicates that the reaction proceeds to a very small extent and the reaction is inadequate. A sufficient amount indicates that the reaction is exactly done, but there is a possibility that a product can be produced from it, whereas an excess of the reaction may make the reaction go in the direction of reducing the energy of the product, so the reaction is sufficient.

Sufficient amount: to cause the other reactant to react in its entirety, which may be just right on its own, or it may be excessive.

Overdose: Causes the other reactant to react in its entirety, in excess of itself, and is present in the reaction product.

Appropriate amount: make yourself and another reactant just react in a moment, and there is no residue in the reaction product.

Sufficient and excessive: It is used when this hidden substance can be consumed in the later reaction foci or can be separated from the desired substance by physical means, i.e., it has no effect on the subsequent operation.

Amount: It is used when the substance cannot be consumed in a later reaction or cannot be physically separated from the desired substance, i.e. when it affects the subsequent operation.

For example, if A and B react, A's explanation of B's mass or other aspects should be:

A: Overdose: That is, after B has completely reacted, A still has a surplus.

Small: The amount that is very small and does not have a great effect on the reaction.

Appropriate amount: It is the amount that when B reacts completely, A also reacts completely.

Equivalence: It is exactly the same amount as B, and it has no way of knowing how it reacts.

Sufficient amount: That is, when B reacts completely, the amount of A may react completely, or there may be a surplus. That is, the amount of A may be moderate or excessive. The minimum amount to ensure a complete reaction of B.

Sufficient means to ensure that the other reactant can be reacted.

Equal means to make the amount of two reactants equal.

In fact, the word "equivalence" is sometimes inaccurate and depends on the context. Sometimes it's equal volume, sometimes it's equal mass, sometimes it's equal to the amount of matter.

To give an example of the obvious difference between equal and sufficient amounts:

Add a sufficient amount of dilute hydrochloric acid to the sodium bicarbonate solution. At this time, dilute hydrochloric acid is generally five times the volume of sodium bicarbonate solution.

If it is changed to the same amount, and it means the same volume, for sodium bicarbonate, dilute hydrochloric acid is insufficient, and only part of the sodium bicarbonate reacts.

The excess is enough to react and there is a surplus, a small amount is a reaction but finally there is a surplus of other reactants but there is no surplus of the input reactants, and the reaction can be continued by continuing to input the reactants.

The appropriate amount is that the reactant is just after the reaction, and there is nothing left.

There should be two kinds of equal targets, and do this experimental reaction, and do two kinds of comparison reactants, one amount is equal to the sufficient amount is enough reaction, between excess and appropriate amount.

In excess, a lot of substances are added, and there is a surplus after the reaction.

A small amount, the added substance is not enough for the reaction.

In moderation, the reaction is basically complete.

The same amount, the same amount as the original amount.

Adequate is the same as overdose.

An overdose is just too much. A small amount is a small amount, but not too little. Moderate amount is a measure of what you feel you can do. An equal amount is an amount in the same proportion as the other. Enough is enough, but not too much.

I relied on me to look upstairs and I was upset when I was chosen.

1.Who says a small amount is not enough to react? A small amount can only be said to be relatively small, and a small amount of sulfuric acid is not often dripped into the book.

You give me more to try. 2.The same amount as the original quantity?

The same amount can only be said to be blended in a certain proportion. 3.Can an adequate amount be the same as an excessive?

Is greater than one the same as greater than or equal to one?

Super unpleasant.

1. Appropriate amount. It can be understood as an appropriate amount and is a vague concept. 2. Sufficient amount.

Including just complete reaction and overdose 3, overdose. 4. A small amount is not explained. It doesn't have to be explained, take the reaction of clarified lime water [Ca(OH)2] and carbon dioxide [CO2] for example.

Appropriate amount refers to the reaction under general conditions: Ca(OH)2+CO2=CaCO3+H2O; Excess refers to the reaction of the product with the addition after the appropriate amount of reaction: (calcium carbonate produced by the previous reaction, water, and carbon dioxide reaction) CaCO3 + H2O + CO2 = Ca(HCO3)2; Coupled with the reaction of the previous step, the total reaction is Ca(OH)2+2CO2=Ca(HCO3)2; A small amount is illustrated by the reaction of aluminum chloride (AlCl3) and sodium hydroxide (NaOH).

Generally speaking, I say that the product of the reaction between aluminum chloride and sodium hydroxide is sodium metaaluminate and sodium chloride and water: AlCl3+4NaOH=Naalo2+3NaCl+2H2O; This is a regurgitation of an adequate amount (sodium hydroxide). When sodium hydrogen is insufficient (in small amounts), it is another reaction:

alcl3+3naoh=al（oh）3+3nacl。There are many other cases. In general, the reaction we generally recognize is in moderation, and the rest is in small amounts or excessive.

But by another standard, the response we usually know may not be moderate. It depends.
