Balancing a Chemical Equation

How to balance a chemical equation? A chemical equation tells us the type of reaction between different reactants. Chemical equation gives the states of the reactants and products.  One can calculate the amount of products required for required amount of products. To balance a chemical equation, very interesting method is algebraic expression method. for example:  C3H8 + O2 -----> CO2  + H2O (adsbygoogle = window.adsbygoogle || []).push({}); The above reaction is to be balanced using algebraic expressions ...

LENS & LENS MAKER'S FORMULA

What is a Lens? A transparent medium bounded by two surfaces, at least one of the surface should be a curved, is said to be a lens and it is said to be THIN LENS, When there is a small gap between the two surfaces or lenses where the thickness are much less and considered negligible in comparison to the radius of curvature. (adsbygoogle = window.adsbygoogle || []).push({}); LENS MAKER'S FORMULA: When a lens of refractive index n2 is placed in the medium of refractive index n1, and the radii of curvatures of lens are R1 and R2, then...
