Answer:
not a reason? if you ask a reason ,i can say An actual yield is the mass of a product actually obtained from the reaction. It is usually less than the theoretical yield. The reasons for this include:
-->incomplete reactions, in which some of the reactants do not react to form the product
practical losses during the experiment
->side reactions (unwanted reactions that compete with the desired reaction)
->reversible reactions
->impurities in reactants
but you asked for not reason then it can be anything lul, like balanced chemical equation, rate of reaction and etc etc ✌️;)
Answer:
B. 3'
Explanation:
Polymerization is the process of forming large molecules by joining together many small molecules. The small molecules are known as the monomers, and the macromolecules are called polymers.
There are two(2) types of polymerization.
a. addition polymerization
b. condensation polymerization
Polymerization is characterized by eliminating small molecules such as water, carbon(IV)oxide, methanol e.t.c.
In complex compounds, polymerization starts at the 3' end of the template.
The reaction, Fe2O3 + 3CO------> 2Fe + 3CO2 is an oxidation-reduction reaction.
An oxidation-reduction reaction is a reaction in which there is a change in oxidation number from left to right in the reaction. This is because, a specie is oxidized and another specie is reduced.
In the reaction; Fe2O3 + 3CO------> 2Fe + 3CO2, we can see that the oxidation number of iron decreased from +3 on the left hand side to zero on the right hand side. The oxidation number of carbon was increased from + 2 to +4.

Sodium chloride is made from one sodium atom and one chlorine atom:
Sodium has a charge of +1, or just +.
Chlorine has a charge of -1, or just -.
These balance out.
Add water to mixture to dissolve sugar then filter. sugared water will be the filtrate while the salt & iron fillings will be the residue. use magnet to attract iron fillings and remaining will be salt.
