A piece of iron(10)moles was dissolved in contrated Hcl.the reaction was form H2 and Fecl2.
determine the amout of Fecl2 formed.
Here is an example I've posted of a simple stoichiometry problem. Just follow the steps.

To determine the amount of FeCl2 formed, we need to balance the chemical equation and then use stoichiometry to calculate the amount of FeCl2 produced.
First, let's balance the equation for the reaction between iron (Fe) and hydrochloric acid (HCl):
Fe + 2HCl -> FeCl2 + H2
The balanced equation shows that 1 mole of iron reacts with 2 moles of hydrochloric acid to produce 1 mole of FeCl2 and 1 mole of hydrogen gas (H2).
Given that you have 10 moles of iron, we can use stoichiometry to calculate the amount of FeCl2 produced.
Since the stoichiometric ratio between Fe and FeCl2 is 1:1, the amount of FeCl2 formed will be equal to the amount of iron used.
Therefore, the amount of FeCl2 formed from 10 moles of iron is also 10 moles.
In conclusion, 10 moles of FeCl2 would be formed when 10 moles of iron react with hydrochloric acid.
