Balance the equationCaO + C -----> CaC2 + CO2 |
|
Answer» 2CaO +5C -----> 2CaC2 + CO2 Solution:CaO+C=CaC2+CO2Ca-1. Ca-1C-1. C-3O-1. O-2to balance C compounds multiply by 3 to the reactant i.e CaO+3C=CaC2+CO2now carbon compounds are balanced.now balance O compounds.....to balance that multiply by 2 on reactant side i.e 2Cao+3C=CaC2+CO2now oxygen compounds get balanced but 2 is multiplied to the the Ca compounds also ...... Therefore to balance the product side multiply by 2 to the reactant side i.e2CaO+3C=2CaC2+CO2but in this while multiplying to Ca also C compounds get multiplied i.e2×2=4 means now carbon compounds become 4......now to balance it on rectant side we have to multiply by 4on Carbon on reactant side....so that we get the answer as 2Cao+4C=2CaC2+CO2 |
