Solution : Whenever two or more than two non-reacting substances are mixed, the resulting system is called a mixture. A solution is a homogeneous mixture of two or more substances in their molecular level. The component having the same physical state as that of the resulting solution is called solvent, the other … Read more
Xenon forms three stable fluorides, XeF2, XeF4, XeF6. The molecular structure of XeF2 is linear, that of XeF4 is square planar and that of XeF6 is pentagonal pyramidal. They are given in the following figure,
Inert gases : The elements of the zero group of the periodic table are known as inert gases. They are also known as noble or rare gases. The inert gases are six in numbers. They are, i) Helium (2He) ii) Neon (10Ne) iii) Argon (18Ar) iv) Krypton (36Kr) v) Xenon … Read more
Chemical kinetics : The branch of physical chemistry which deals with the study of the speed or rate of chemical reactions and also the explanation of their mechanism is called chemical kinetics. The study of chemical kinetics includes, i) The rate of a reaction and rate laws. ii) The … Read more
Conjugate acid-base : The base formed by the donation of a single proton by an acid is called the conjugate base of the acid. Similarly, the acid formed by the acceptation of a single proton by a base is called the conjugate acid of the base. Conjugate acid-base pair : … Read more
Differences between order and molecularity: Order No. Molecularity It is the sum of powers of the concentrations in the rate law expressions. 01 It is the number of molecular of reactants taking part in an elementary reaction or in a rate determining step of a complex reaction. Order corresponds to the overall reaction. 02 Molecularity … Read more
The following post highlights some good programming practices what beginner programmer can follow. Applying these increases the readability of codes, will make make codes more easier to update. Well, individual programmers should have their own programming styles to maintain, but still there are some practices that the beginners can follow. With times every programmers find … Read more
Merging Sort: Merging sort requires two previously sorted array which will be merged into one single array which will be a sorted array. If the source arrays are not sorted then the algorithm won’t work. If you need to sort two unsorted arrays then you can place one array after another then operate the new … Read more
Garbage collection. What you get from the title of the topic? Well, while we are coding we use variable or memory location. We may need an array initially for storing some initial elements, then we take more arrays while we are manipulating. At some part of the manipulation, it may that we dont need the … Read more
