NECO 2018 Chemistry Answers
1a) Isotopes are atoms of the same element having the same numbers of protons, but different numbers of neutrons. They have same chemical properties due to the same electronic configuration but different physical properties.
II) isomerism is the existence of molecules that have the same numbers of the same kinds of atoms (and hence the same formula) but differ in chemical and physical properties.
i) Chlorine is commonly used as an antiseptic
ii) it is used to make drinking water safe and to treat swimming pools.
iii) chlorine are used in many industrialprocesses, such as in the productionof paper products, plastics, dyes, textiles, medicines, antiseptics, insecticides, solvents and paints.
3a) homologous series is a series of compounds with the same functional group and similar chemical properties. Compounds within a homologous series typically have a fixed set of functional groups that gives them similar chemical and physical properties.
3aii) The members of a particular homologous series have almost same chemical properties due to presence of same functional group.
ii) The physical properties(like solubility, melting point, boiling point, state) of members of a homologous series either gradually increase or decrease with increase in molecular mass.
iii) Members of a homologous series can be represented by a general formula.
3b) catalyst is any substance that increases the rate of a reaction without itself being consumed.
3bii) A catalyst increases the speed of a reaction, and it also improves the yield of the intended product.
2. A catalyst actually takes part in the reaction even though it itself is not consumed or used up in the course of the reaction.
3. A catalyst makes the reaction faster by providing an alternative pathway with a lower activation energy.
