Explanation

Turpentine is commonly used as a solvent in the manufacture of paints and inks.

It helps to dissolve pigments and improves the consistency and drying of the paint.

Explanation

A single chlorine atom from CFCs can destroy up to 100,000 ozone molecules before being deactivated.

This chain reaction is what makes chlorine so dangerous for the ozone layer.

Explanation

The concentration of a solution is calculated by dividing the amount of solute by the volume of solvent.

In this case, 30 grams of sugar in 0.1 litre of water gives the highest concentration.

Explanation

Aqua regia (a mixture of HCl and HNO₃) is strong enough to dissolve gold, platinum, and palladium.

Silver and iridium do not dissolve in aqua regia easily.

Explanation

Herbicides also known as Weedkillers.

It is used to control undesired plants.

Explanation

The ability of metals to be drawn into thin wires is known as ductility.

This property allows metals to be stretched without breaking.

This making them useful in various applications.

Explanation

In a zero-order reaction, the rate of reaction is independent of the concentration of the reactants and is equal to the rate constant k.

The rate equation for a zero-order reaction is  Rate=k, where the rate of reaction is constant and does not change with varying concentrations of reactants. 

Explanation

PHRV (Polyhydroxyalkanoates) is a type of biodegradable polymer.

It is produced by microorganisms and can be broken down by natural processes, making it environmentally friendly compared to other polymers.

Explanation

In an isothermal process, the temperature of the system remains constant.

According to the first law of thermodynamics, for an ideal gas, if the temperature is constant, the internal energy does not change.

Therefore, the change in internal energy is zero (ΔU = 0).

Explanation

In chromatographic analysis, the principle used is adsorption, where the components of a mixture interact with the stationary phase and are separated based on their differing affinities for the stationary phase.
