[@HappyDodoBird-wz1ju]

in question 17 b is also correct because zinc and copper both are transition elements

[@vangojusrija3866]

In d-block elements every element is not a transition elements, to become transition elements in d orbital we should have atlest one un filled orbital to perform d-d transition, next coming to zinc there is no incomplete d orbital so it is not a transition element

[@vangojusrija3866]

Yah zn is not the transition element

Nitrous Oxide

[@SaiGaneshchowdaryambati-d6v]

Solution for 39th que sir

[@faisukaan3754]

Remember, CaCO3 is the one compound which have wholly Solly 100g . So it is very easy to calculate individual % in it. Each Element will have the same percentage as its molecular mass in the compound CaCO3. Let, CaCO3=Ca(40)+C(12)+O3(3×16=48) Adding these; CaCO3=40+12+48=100g Therefore Ca=40%,C=12% and O3 mean oxygen=48%. Also you can find out percentage of element in compound by formula: % of element= Atomic mass of element×no.of elements in that compound×100/Atomic mass of whole compound So, % of Ca= Atomic mass of Ca×No.of Ca in Compound CaCO3 ×100/Compound whole molecular mass % of Ca=40×100/100=40% Ans. Remember me in your prayers ❤
