In this chemical equation, how many atoms do the reactants represent? 4 Fe + 3 02 -> 2 Fe2o3

1 answer:

5 0

Numbers to the right represent how many atoms participate.

4Fe = 4 atoms of Iron

3O2 = 3 molecules of Oxygen containing 2 atoms each. 3*2 = 6 atoms. So there are 10 atoms of reactantants which participates to form 2Fe2O3.

Answer:

8L of CO2

Explanation:

The equation for the reaction is given below:

2C2H2 + 5O2 —> 4CO2 + 2H2O

From the equation above,

5L of O2 produced 4L of CO2.

Therefore, 10L of O2 will produce = (10 x 4)/5 = 8L of CO2

Therefore, 8L of CO2 is produce
