Automobile bodies contain significant amounts of iron. The iron is protected by the addition of zinc. This is called galvanizati

Oksana_A [137]

Answer: The balanced chemical equation is written below.

Explanation:

Galvanization is defined as the process in which a protective layer of zinc is applied to iron or steel to prevent the metal from rusting.

Zinc prevents the oxidation of iron and acts as a reducing agent in the process.

The half reaction for the process follows:

Oxidation half reaction: $Zn\rightarrow Zn^{2+}+2e^-$

Reduction half reaction: $Fe^{2+}+2e^-\rightarrow Fe$

Net chemical equation: $Zn+Fe^{2+}\rightarrow Zn^{2+}+Fe$

Hence, the balanced chemical equation is written above.

When an aqueous solution of KBr is electrolyzed,

zhenek [66]

KBr + H2O = KOH + Br2 + H2

So we know that we need a 2 on the left of kbr so it would equal the right Br.

=2KBr
now put a 2 in front of KOH since we need a 2k on right side

Now we put a 2 infront of H2O which wil make 4 h's and 2 o's

2h2o

now it is balanced

2KBr + 2H2O = 2KOH + Br2 + H2
