Actually the word co-ligative itself reveals that (“co” means each other and “ligative” means related) These are the properties which are related to each other. The colligative properties are those properties that depend on the number of solute particles in a solution or a mixture. “These properties don’t depend upon the nature of particles “. Following are the colligative properties:- […]
The answer to this question is very simple . There are two major reasons behind it. 1. Catenation :- It is the property by which the carbon can make long chains, branched chains and ring or cylic structural by joining with its own atoms. Due to this it can make a variety of molecules. 2. Tetravalency :- carbon has 4 […]
Meaning of diprotic acid is that , it can loose two hydronium ions (H+) . For finding how many H+ ions it can give , we have to see its […]
The structure of XeOF4 is square pyramidal. And its hybridization is sp³d² The structure of XeO3 is pyramidal and its hybridization is sp³.
Chlorobenzene and bromobenzene can be prepared by treating bezenediazonium chloride with cuprous chloride or cuprous bromide. This reaction is also called Sandmeyer’s reaction.
Actually the sigma bond involves head to head overlapping of orbitals, due to which the overlapping takes place on a larger extent. That makes the bond more stronger as compared to pie bond. In pie bond there is a sidewise overlapping of orbitals which leads to lesser extent of overlapping and thus the bond formed is not so strong as […]
It states that for a solution of volatile components, the partial vapour pressure of each component is directly proportion to the mole fraction of the component in the solution.
1.Temperature :- With increase in temperature the rate of vaporization also increase thus it creates more pressure. Moreover with increase in temperature the kinetic energy of the vapours also increase. 2. Nature of liquid:- The liquids with lower inter-particulate attractions have high vapour pressure as the formation of vapours is easy . Like acetone is easily vaporized as compared to […]
The substances whose conductivity lies between 10-⁶ to 10⁴ ohm-¹ . The range lies between conductors and insulators. Types 1. n-type :- These type of semiconductors have excess electrons present […]
It is the number of lattice points touching one lattice point in a crystalline solid. For example in case of Sodium chloride it is 6 .
1. Paramagnetism :- This is the phenomenon by which substances are weekly attracted by the magnetic field. It arises because the substances are magnetized in the same direction of the […]
Calculate the radius of copper atom if it crystallise in face centred cubic lattice and has a density of 8.93 g / cm cube. Solution Structure given = fcc For […]
To understand this concept we must be aware of Threshold energy or activation energy. The threshold energy or the activation energy is the minimum amount of energy that is required for the conversion of reactants into the products . According to collision theory the reactant species collide with each other to make the product. But every collision don’t bring about […]
The decreasing order of reactivity will be as follows:- HI > HBr > HCl In case of reactivity the HI will be the most reactive and then HBr and least reactive will be the HCl. This is due to the fact that the reducing character of Iodine is highest and it can easily break the H-I bond and thus can […]
The answer is simple just look at the combustion reaction of the hydrogen and you will get water.
#accomodation #of #light In our day to day life we face various exposure to light. The intensity of rays vary from source to source some are intense and some are […]
Interesting fact about Owl We all know that the owl is capable of night vision due its special eyes. But more than this I have noticed a unique feature in […]
What kind of teeth are there in frog ? The type of dentition in case of frog 🐸 is Homodont and Polyphyodont . The meaning of these terms will clarify […]
Why we add coolent in the radiator of car ? How does a radiator of car works? We all are familiar with the coolent that is normally used in radiators […]
Yes we say , we say . Wait for me, hey , hey , hey. We know it hurts, Its hard to say , yeah Oh yeah… You know its […]
