In <span>c2h4o2 there are
2 atoms of carbon
4 atoms of hydrogen
2 atoms of oxygen

Hydrogen atomic masses is 1 which was very low so 4 of them would still be the lowest mass percent. Then we have carbon and oxygen which both have 2 atoms. Oxygen atomic mass is more than carbon atomic mass, so oxygen should contribute more mass percent composition. The sequence from higher mass percent composition should be:
1. Oxygen
2. Carbon
3. Hydrogen</span>

BALANCE the equation
Anna11 [10]

Answer:

1. 4FeCl3 + 3O2 → 2Fe2O3 + 6Cl2

2. 6 moles of Cl2

Explanation:

1. The balanced equation for the reaction. This is illustrated below:

4FeCl3 + 3O2 → 2Fe2O3 + 6Cl2

2. Determination of the number of mole of Cl2 produce when 4 moles of FeCl3 react with 4 moles. To obtain the number of mole of Cl2 produced, we must determine which reactant is the limiting reactant.

This is illustrated below:

From the balanced equation above,

4 moles of FeCl3 reacted with 3 moles of O2.

Since lesser amount of O2 (i.e 3 moles) than what was given (i.e 4 moles) is needed to react completely with 4 moles of FeCl3, therefore FeCl3 is the limiting reactant and O2 is the excess reactant.

Finally, we can obtain the number of mole Cl2 produced from the reaction as follow:

Note: the limiting reactant is used as it will produce the maximum yield of the reaction since all of it is used up in the reaction.

From the balanced equation above,

4 moles of FeCl3 will react to produced 6 moles of Cl2.
