Question

Balance the following chemical equations:
a) Al +02 _ A1203
b) NaOH +H2SO4 _ Na2S04+2H20
c) FeCl2+C12 _ FeCl3​

Answer 1

Answer:

a) →

b) $2NaOH + H_{2}SO_{4}$ → $Na_{2}SO_{4} + 2H_{2}O$

c) $2FeCl_{2} + Cl_{2}$ → $2FeCl_{3}$

Answer 2

Answer :

$\bold{4Al+3O_{2}\rightarrow2Al_{2}O_{3}}$

• Al = 4 atoms [L.H.S]
• Al = 2(2) = 4 atoms [R.H.S]
• O = 6 atoms [L.H.S]
• O = 2(3) = 6 atoms [R.H.S]

∴ The above equation is balanced.

$\bold{2NaOH+H_{2}SO4\rightarrow Na_{2}SO_{4}+2H_{2}O}$

• Na = 2 atoms [L.H.S]
• Na = 2 atoms [R.H.S]
• O = 2 + 4 = 6 atoms [L.H.S]
• O = 4 + 2 = 6 atoms [R.H.S]
• H = 2 + 2 = 4 atoms [L.H.S]
• H = 4 atoms [R.H.S]
• S =  1 atom [L.H.S]
• S = 1 atom [R.H.S]

∴ The above equation is balanced.

$\bold{2FeCl_{2}+Cl_{2}\rightarrow 2FeCl_{3}}$

• Fe = 2 atoms [L.H.S]
• Fe = 2 atoms [R.H.S]
• Cl = 2(2) + 2 = 6 atoms [L.H.S]
• Cl = 2(3) = 6 atoms [R.H.S]

∴ The above equation is balanced.
