a)
C3H7OH(l) + O2(g) --> CO2(g) + H2O(g)
balancing equation
consider C
In the reactant side there are 3 C so multiply CO2 by 3 on product side
C3H7OH(l) + O2(g) --> 3CO2(g) + H2O(g)
consider H
In the reactant side there are 8 H so multiply H2O by 4 on product side
C3H7OH(l) + O2(g) --> 3CO2(g) + 4H2O(g)
consider O
In the product side there are 10 O so multiply O2 by 9/2 on reactant side
C3H7OH(l) + 9/2O2(g) --> 3CO2(g) + 4H2O(g)
Multiply by 2 on both sides
2 C3H7OH(l) + 9 O2(g) --> 6 CO2(g) + 8 H2O(g)
b)
Cd(NO3)2(aq) + K3PO4(aq) --> Cd3(PO4)2(s) + KNO3(aq)
balancing equation
consider Cd
In the product side there are 3 Cd so multiply Cd(NO3)2 by 3 on reactant side
3 Cd(NO3)2(aq) + K3PO4(aq) --> Cd3(PO4)2(s) + KNO3(aq)
consider N
In the reactant side there are 6 N so multiply KNO3 by 6 on product side
3 Cd(NO3)2(aq) + K3PO4(aq) --> Cd3(PO4)2(s) + 6 KNO3(aq)
consider K
In the product side there are 6 K so multiply K3PO4 by 2 on reactant side
3 Cd(NO3)2(aq) + 2 K3PO4(aq) --> Cd3(PO4)2(s) + 6 KNO3(aq)
consider O,p
both are balanced in the above equation
so
equation is
3 Cd(NO3)2(aq) + 2 K3PO4(aq) --> Cd3(PO4)2(s) + 6 KNO3(aq)
c)
Zn(s) + HCl(aq) --> ZnCl2(aq) + H2(g)
balancing equation
consider Zn
it is balanced
consider H
In the product side there are 2 H so multiply HCl by 2 on reactant side
Zn(s) + 2 HCl(aq) --> ZnCl2(aq) + H2(g)
consider Cl
it is balanced in the above equation
so
equation is
Zn(s) + 2 HCl(aq) --> ZnCl2(aq) + H2(g
d)
Ba(OH)2 (aq) + HBr(aq) --> H2O(l) + BaBr2(aq)
consider Ba
it is balanced
consider Br
In the product side there are 2 Br so multiply HBr by 2 on reactant side
Ba(OH)2 (aq) + 2 HBr(aq) --> H2O(l) + BaBr2(aq)
consider H
In the reactant side there are 4 H so multiply H2O by 2 on product side
Ba(OH)2 (aq) + 2 HBr(aq) --> 2 H2O(l) + BaBr2(aq)
consider O
it is balanced in the above equation
so
equation is
Ba(OH)2 (aq) + 2 HBr(aq) --> 2 H2O(l) + BaBr2(aq)
