- Q1. What is the difference between molarity & molality? And also explain which one extensive or intensive properties.
- Ans.
Molarity is the concentration of a solution in terms of moles of solute per liter of solution, while molality is the concentration of a solution in terms of moles of solute per kilogram of solvent.
Molarity is an extensive property, while molality is an intensive property.
Molarity changes with temperature and pressure, while molality remains constant.
Molality is preferred in calculations involving colligative properties...
- Q2. What is difference between vapour pressure and partial pressure.
- Ans.
Vapour pressure is the pressure exerted by a vapour in equilibrium with its liquid or solid form, while partial pressure is the pressure exerted by a single gas in a mixture.
Vapour pressure is specific to a substance, while partial pressure is a property of a gas in a mixture.
Vapour pressure is dependent on temperature, while partial pressure is dependent on the concentration of the gas in the mixture.
In a mixture of g...
- Q3. Tell me about the Arrhenius equation.
- Ans.
The Arrhenius equation describes the relationship between the rate constant of a chemical reaction and temperature.
The equation is given as k = Ae^(-Ea/RT), where k is the rate constant, A is the pre-exponential factor, Ea is the activation energy, R is the gas constant, and T is the temperature.
The Arrhenius equation helps to explain the effect of temperature on reaction rates.
Higher temperatures generally lead to hig...
- Q4. Explain about the difference between entropy and enthalpy?
- Ans.
Entropy is the measure of disorder or randomness in a system, while enthalpy is the measure of heat energy in a system.
Entropy is a state function, while enthalpy is a path function.
Entropy increases with an increase in disorder, while enthalpy increases with an increase in heat energy.
Entropy is represented by the symbol S, while enthalpy is represented by the symbol H.
Entropy is measured in joules per kelvin (J/K), w...

Common examples of salt include sodium chloride (table salt), potassium chloride, and calcium chloride
Salt is formed through the reaction of an acid with a base, resulting in the neutraliza...
- Q5. If we react iodine with alcohol what is the byproduct
- Ans.
The byproduct of reacting iodine with alcohol is iodoalkane.
When iodine reacts with alcohol, it replaces the hydrogen atom in the alcohol molecule.
The resulting compound is called iodoalkane or alkyl iodide.
The reaction is an example of a substitution reaction.
For example, when iodine reacts with ethanol, the byproduct is ethyl iodide.
- Q6. Why we shouldn't keep mango pickle in aluminium foil
- Ans.
Aluminium reacts with the acidic content of mango pickle, leading to the formation of harmful compounds.
Aluminium reacts with the acidic content of mango pickle
This reaction can lead to the formation of harmful compounds
These compounds can contaminate the pickle and make it unsafe for consumption
- Q7. Ifan element x keep on period 14 what will be its structure
- Ans.
The structure of an element in period 14 depends on its atomic number and electron configuration.
Elements in period 14 can have various structures depending on their atomic number.
The structure can be determined by the electron configuration of the element.
For example, if element X has an atomic number of 57, its structure would be [Xe] 4f^14 5d^1 6s^2.
- Q8. Group 17 elements also known as what
- Ans.
Group 17 elements are also known as halogens.
Group 17 elements are highly reactive nonmetals.
They have 7 valence electrons and tend to gain 1 electron to achieve a stable octet.
Halogens include fluorine, chlorine, bromine, iodine, and astatine.
They are found in various compounds and play important roles in chemistry and biology.
