USING ENGLISH TO PREDICT RENDEMENT OF PRODUCT A REACTION

Types of chemical reactions:
A.Burning.
Burning is a reaction in which an element or compound with oxygen forms a simple oxygen-containing compound.
Example :
CO2, H2O and SO2
C3H8 (9) + 5O2 (9) → 3CO2 (9) + 4H2O (9)
2C6H14O4 (9) + 15O2 → 12Co2 (9) + 14H2O (9)

B.Collection (synthetic)
A reaction in which a more complex substance is formed from two or more simpler substances (both elements and compounds).
2H2 (9) + O2 → 2H2O (9)
CO (9) + 2H2 (9) → CH3OH (9)

C.Indoning
Is a reaction in which a substance is broken down into simpler substances 2Ag2O (p) → 4Ag (p) + O2 (9)

D.Changes (Shift date)
Is a reaction in which an element is transferred to another element in a compound. Cu (p) + 2Ag + (ag) CU2 + (ag) + 2 Ag (p)

E.Metatesis (transfer date)
Is a reaction where there is exchange between two reactions.
AgNo3 (ag) → NaCL (ag) → AgCL (p) + NaNO3 (ag)

The best way to give a chemical reaction is to write a balanced chemical equation which is a qualitative and quantitative statement of the reactants involved. Each substance is represented by its molecular formula. Express the number of atoms of all kinds in a unit of that substance. The molecular formula is a multiplier of the empirical formula of the substance that states
The minimum amount possible in the correct comparison of atoms of each kind. The three general classes of reactions encountered with melaus in chemistry are direct combination reactions, simple change reactions and double preconditioning reactions. Quantitative relationships between reactants and reaction products in a balanced chemical equation provide a stripometric basis.
The calculation of staikiomentry requires the use of elemental weight of the element and the weight of the compound molecule. The amount of a certain reaction which is calculated will be obtained in a theoretical rendement chemical reaction for a chemical reaction. It is important to know which are limiting reagents ie reagents that can theoretically react to exhaustion, whereas other reagents are excessive.
If chemical reactions occur, three kinds of changes can be observed: a. Changes in Nature
B.Change Changes
C. Energy Changes

All chemical changes are certainly parent on the law of preservation of energy laws and the law of mass energy preservation. A certain composition of senyawakimia by the law of comparative order and comparative law resides. The fundamental fundamentals underlying all the changes of chemistry are the theoretical chemistry areas, the correlation between the concepts of elements and compounds with the four laws mentioned above is obtained in Dalton Theory of Dalton, the first modern theory of atoms and molecules as fundamental particles of matter The ingenuity that grows out of this theory is, among other things, the scale, the relative atomic weight of the elements dissolved according to the increase of atomic weight, the appearance of the elements regularly with certain properties encourages the meddeleu to arrange periodical tables of the elements and predict the existence of some elements not yet known.

To obtain a percentage yield, multiply the fractional yield by 100%.

One or more reactants in chemical reactions are often used redundantly. The theoretical rendement is calculated based on the number of moles of the limiting reagent. For this calculation, it is usually assumed that there is only one reaction involved.

The ideal chemical yield value (theoretical rendement) is 100%, a value highly unlikely to be achieved in its practice. Calculate the percentage of rendement that is by using the following equations percent rendemen = weight yield / weight of yield divided by the sample weight multiplied by 100%
