Question

Write five important limitations or drawbacks of a chemical equation.​

Answer 1

Answer:

A chemical equation has its own limitations. They do not provide information about: The physical state of reactants and products Hence, the symbols 's' for solid, 'l' for liquid, 'g' for gas and 'vap' for vapour are added. Conditions such as temperature, pressure and catalyst affecting the reaction.Word equations can be very useful, but do have one major drawback. They cannot be used for any quantitative work. A word equation does not tell how many moles of each material are needed or how many moles of product are formed.but it does not give the following information: (i) The physical state of the reactants and products whether these are solids, liquids or gaseous etc. (ii) Concentration of reactants and products. (iii) Condition of reaction such as temperature, pressure, catalyst, light.
