Question

Balance the chemical equation by adding in the proper coefficients. chemical equation: MnO2 + H+ + C,02 Mn2+ + H2O + CO2

Answer 1

chemical equation Mnai thi + 42 Mit2+H₂O +co, Here Mooi is going under enduction and C2042 is getting oxidised Steps seperate skeletal reaction in too half- reaction oxidation : 20,2 co2 Reduction : Mnou - Mot2 than in in H and readant rea o. As and II in Step 2) Balance the luce the atoms atoms other other carbon in oxidation sxn is a product (2002 - 2002 Step3: Balance o atoms in both reactions by adding water molecules. Mnoi Mn+2 + Algo C90 2 2002 Coare already balance Balance to atoms by adding titions. (Add 825 ion ou dift side of reduction reaction Mnou +84 Mr12 +410 20,2 2002 Steps! Balance the change in two half reaction by adding electrons to the Mnoy + 8H+ + se - Mot2 + 4H₂O 6042 200g + 20

Now to equalise number of electrons, mut oxidation hay reaction by 5' ar and reduction half ion by 5 5C₂ 042 & loco al nou +IGHT +10e - + 10 e- 2M2t2 + 8H₂O Sep obtain net on both sides. 0 breaction after Add two hay reaction to coon after cancelling electron cancelling loco +2Mt2 + & H2O 502042 + 2Mnai + 16H+ - This is balanced chemical reaction.
