WHAT IS SOLUTION?, And Different types of Solutions

Image
A binary solution is nothing but a homogeneous mixture of two substances. These two substances or components are the solute and the solvent.  The solute is the substance that gets dissolved. It is present in a smaller quantity. On the other hand, the solvent is the substance that dissolves the solute. It is present in a comparatively larger quantity. There are different types of solutions. But, what is the basis of their differentiation?   Types of Solutions Solutions are of different types, based on a number of criteria, like the difference in the solute or the solvent etc. Let us now look at the different types of solutions, based on different criteria. On the basis of water as Solvent  Based on the whether the solvent is water or not, solutions are of two types. Aqueous solutions:  These solutions have water as the solvent .  Examples of such solutions are sugar in water, and carbon dioxide in water, etc. Non-Aqueous Solutions:   These solutions have a solvent th

What Is Humalin ????

Image
  What Is Humalin ? Humulin  is the man-made insulin, which is made by the recombinant DNA by genetic engineering. Humulin  R (insulin (human recombinant)) is a hormone that is produced in the body used to treat diabetes.   A small piece of circular DNA called a plasmid is extracted from the bacteria cell or yeast. Humulin N is injected under the skin. It should not be injected into muscle or veins. Doses of insulin are measured in units. U-100 insulins, including Humulin N, contain 100 units/mL. With the Humulin N U-100 vial, it is important to use a syringe that is marked for U-100 insulin preparations.

Is entropy of universe constant? ///Second law of thermodynamics.

Image
  Class 11 Chemistry   Is entropy of universe constant? Answer:-   No, the entropy of the universe always increases in the course of every spontaneous change. It is the second law of thermodynamics. Define combined form of first and second law of thermodynamics. Answer: - In thermodynamics, the combined law of thermodynamics, also called the Gibb’s fundamental equation, is a mathematical summation of the first law of thermodynamics and the second law of thermodynamics summed into a single concise mathematical statement as dU- TdS + PdV ≤ 0 Where dU is a variation in internal energy. T is temperature, dS is variation in entropy P is pressure dV is variation in volume of a simple working body in which there is neither flows of particles out of the body nor external forces, other than gravity, acting on the body. In theoretical structure, in addition to the obvious inclusion of the first two laws, the combined law incorporates the implications of the zeroth law, via temperature T and the
