Question

write the the balance molecular equations for the following word equations
(only correct answers)​

Answer 1

Answer :-

Balanced equation :- The equation in which the Molecular mass of Reactants side is equal to that of products side is called balance equation

Reason to balance equation

• We balance the equation to satisfy the law of conservation of mass which states that the mass is neither be created nor be destroyed

$\sf\ a)\it\ Carbon+ Nitric Acid \xrightarrow \ Carbon \ dioxide+ Nitrogen\ dioxide+ Water\\ \\ \sf\ C+4HNO_3 \xrightarrow\ CO_2+4NO_2+2H_2 O\\ \\ \\ \sf \ b)\it\ Ammonium\ Nitrate \longrightarrow\ Nitrous\ Oxide+Water\\ \\ \sf\ NH_4NO_3\longrightarrow\ N_2O+2H_2O\\ \\ \\ c) \it \: Zinc\ sulphide+Oxygen\longrightarrow\ Zinc\ Oxide+ Sulphuric\ \:dioxide\\ \\ \sf\ 2ZnS+3O_2\longrightarrow\ 2ZnO+ 2SO_2\\ \\ \\ d)\it Nitrogen+ Hydrogen\longrightarrow\ Ammonia\\ \\ \sf\ N_2+3H_2\longrightarrow\ 2NH_3\\ \\ \\ e)\it\ Aluminum+ Oxygen\longrightarrow\ Aluminium \ Oxide\\ \\ \sf\ 4Al+ 2O_2\longrightarrow\ 2Al_2O_3\\ \\ \\ f) \it\ Carbon\ dioxide+ Carbon\longrightarrow\ Carbon\ monoxide\\ \\ \sf\ CO_2+ C\longrightarrow\ 2CO$

Answer 2

Nitrogen dioxide is a chemical compound with the formula NO2 .It is one of several nitrogen oxides. NO2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas. It can be fatal if inhaled in large quantity.Nitrogen dioxide is a paramagnetic, bent molecule with C2v point group symmetry.
