A balanced chemical equation is analogous to a recipe for chocolate chip cookies. It shows what reactants (the ingredients) combine to form what products (the cookies). It also shows the numerical relationships between the reactants and products (such as how many cups of flour are required to make a single batch of cookies). These numerical relationships are known as reaction stoichiometry, a term derived from the Ancient Greek words stoicheion ("element") and metron ("measure"). In this article, we'll look at how we can use the stoichiometric relationships contained in balanced chemical equations to determine amounts of substances consumed and produced in chemical reactions. A common type of stoichiometric relationship is the mole ratio, which relates the amounts in moles of any two substances in a chemical reaction. We can write a mole ratio for a pair of substances by looking at the coefficients in front of each species in the balanced chemical equation. For example, consider the equation for the reaction between iron(III) oxide and aluminum metal: Fe 2 O 3 ( s ) + 2 Al ( s ) → 2 Fe ( l ) + Al 2 O 3 ( s ) \text_3(s) Fe 2 ​ O 3 ​ ( s ) + 2 Al ( s ) → 2 Fe ( l ) + Al 2 ​ O 3 ​ ( s ) start text, F, e, end text, start subscript, 2, end subscript, start text, O, end text, start subscript, 3, end subscript, left parenthesis, s, right parenthesis, plus, start color #11accd, 2, end color #11accd, start text, A, l, end text, left parenthesis, s, right parenthesis, right arrow, s...

Read and download NCERT Book for Class 12 Chemistry Alcohols Phenols And Ethers Class 12 Chemistry students should refer to the following NCERT Book Alcohols Phenols And Ethers in Class 12. This NCERT Book for Class 12 Chemistry will be very useful for exams and help you to score good marks Alcohols Phenols And Ethers NCERT Book Class 12 You have learnt that substitution of one or more hydrogen atom(s) from a hydrocarbon by another atom or a group of atoms result in the formation of an entirely new compound having altogether different properties and applications. Alcohols and phenols are formed when a hydrogen atom in a hydrocarbon, aliphatic and aromatic respectively, is replaced by –OH group. These classes of compounds find wide applications in industry as well as in day-to-day life. For instance, have you ever noticed that ordinary spirit used for polishing wooden furniture is chiefly a compound containing hydroxyl group, ethanol. The sugar we eat, the cotton used for fabrics, the paper we use for writing, are all made up of compounds containing –OH groups. Just think of life without paper; no note-books, books, newspapers, currency notes, cheques, certificates, etc. The magazines carrying beautiful photographs and interesting stories would disappear from our life. It would have been really a different world. An alcohol contains one or more hydroxyl (OH) group(s) directly attached to carbon atom(s), of an aliphatic system (CH3OH) while a phenol contains –OH group(s) dir...
