4. BALANCE THE FOLLOWING EQUATIONS : |
|
Answer» a) CH4+O2=CO2+H2O Here, on reactant side, C=1. H=4. and O=2 On product side, C=1. O=2+1. and H=2 Therefore, multiply (H2O) by 2 Now, CH4+O2=CO2+2(H2O)=BALANCED EQUATION b) PbO2=PbO+O2 Here, reactants, Pb=1. O=2 And products, Pb=1. O=1+2 Therefore, multiply (PbO) on product side by 2 PbO2=2(PbO)+O2 Now multiply (PbO2) on reactant side by 2 Therefore the balanced chemical equation is 2(PbO2)=2(PbO)+KE c)Ca+N2=Ca3N2 Reactant, Ca=1. N=2 Product, Ca=3 N=2 Therefore multiply (Ca) on reactant side by 3 Hence the balanced chemical equation is 3(Ca)+N2=Ca3N2 d)N2+H2=NH3 Reactant, N=2. H=2 Product, N=1. H=3 Therefore multiply N on product side by 2 N2+H2=2(NH3) Now multiply (H2) on reactant side by 3 Therefore the balanced chemical equation is N2+3(H2)=2(NH3) e) NaNO3=NaNO2+O2 Reactant, Na=1. N=1. O=3 Product, Na=1. N=1. O=2+2 Therefore multiply (NaNO3) on reactant side by 2 2(NaNO3)=NaNO2+O2 Now multiply (NaNO2) on product side by 2 Therefore the balanced chemical equation is 2(NaNO3)=2(NaNO2)+O2 Hope it HELPS u...!!!!.... |

Classification of hydrocarbon |
|
Answer» Saturated Hydrocarbons: In these compounds, carbon-carbon atoms and carbon-HYDROGEN atoms are held together by single BONDS. These single bonded compounds are the simplest hydrocarbons. These types of hydrocarbons don’t have double or triple bonds. In terms of hybridization, they have Sp3 hybridised carbon atom with no SP2 or Sp hybridised Carbon atoms. They are together CALLED as alkanes which have a general formula CnH2n+2. For example, CH4C3H6. Unsaturated Hydrocarbons: These compounds consist of a single, double or a triple bond between carbon-carbon atoms. The double-bonded compounds are called alkenes and the triple bonded compounds are called alkynes. The general formula for alkenes is CnH2n and for alkynes the general formula is CnH2n-2. Cycloalkanes: These hydrocarbons possess one or multiple carbon rings. The hydrogen atom is attached to the carbon ring. Aromatic Hydrocarbons: These are also called as arenes. Arenes are compounds which consist of at least one aromatic ring. Aliphatic Hydrocarbons: They are straight chain STRUCTURES having no rings in them. Alicyclic Hydrocarbons: They are hydrocarbons having a ring structure in them. The carbons atoms can be Sp, Sp2 or Sp3 hybridised Hope it is helpful. |
