2Fe+ 6HBr  --->  2FeBr3  +3H2
Fe   is a   reducing   agent  is  what  that  is true  in  equation  above 
  This  is  because  it   oxidation  state  move  from   zero  to    positive   three.Reducing  agent    is  an  element  or  compound  that  loses  or   donate  an electron  to  another  chemical   species  in  a  redox  chemical  reaction.  Fe  is  oxidized  since  it  loses  electron  in the  redox   reaction

e-lub [12.9K]

Answer:

C6H12O6 —> 2C2H5OH + 2CO2

Explanation:

The equation for the reaction is given below:

C6H12O6 —> C2H5OH + CO2

We can balance the equation above as follow:

There are 12 atoms of H on the left side and 6 atoms of the right side. It can be balance by putting 2 in front of C2H5OH as shown below:

C6H12O6 —> 2C2H5OH + CO2

There are 6 atoms of C on the left side and 5 atoms on the right side. It can be balance by putting 2 in front of CO2 as shown below:

C6H12O6 —> 2C2H5OH + 2CO2

Now the equation is balanced.
