Question

H2S+O2=S+H2O AL+CL2=ALCL3 Cu+N2=Ca3N2KBr+CL2=Br2+KCl

Answer 1

2H2S+O2=2S+2H2O     2AL+3CL2=2ALCL3   3Ca+N2=Ca3N2 2KBr+CL2=Br2+2KCl

Answer 2

H2S + O2 = S + H2O: The chemical equation you provided represents the reaction between hydrogen sulfide (H2S) and oxygen (O2) to form sulfur (S) and water (H2O). This is a combustion reaction where hydrogen sulfide reacts with oxygen to produce sulfur dioxide and water vapor. The balanced equation for this reaction is:

2H2S + 3O2 = 2SO2 + 2H2O [[1]]

AL + CL2 = ALCL3: The equation you provided represents the reaction between aluminum (Al) and chlorine (Cl2) to form aluminum chloride (AlCl3). This is a synthesis reaction where aluminum reacts with chlorine to produce aluminum chloride. The balanced equation for this reaction is:

2Al + 3Cl2 = 2AlCl3 [[2]]

Cu + N2 = Ca3N2: The equation you provided represents the reaction between copper (Cu) and nitrogen (N2) to form calcium nitride (Ca3N2). This is a synthesis reaction where copper reacts with nitrogen to produce calcium nitride. The balanced equation for this reaction is:

3Cu + N2 = Ca3N2 [[3]]

KBr + CL2 = Br2 + KCl: The equation you provided represents the reaction between potassium bromide (KBr) and chlorine (Cl2) to form bromine (Br2) and potassium chloride (KCl). This is a displacement reaction where chlorine replaces bromine in potassium bromide to form potassium chloride and bromine. The balanced equation for this reaction is:

2KBr + Cl2 = 2KCl + Br2 [[4]]

Please note that these equations are balanced and represent the stoichiometry of the reactions. The coefficients in front of the chemical formulas indicate the number of moles of each substance involved in the reaction.
