Write and balance an equation for a reaction in which iron (Fe) and hydrochloric acid (HCL) reacto to form iron chloride (FeCl2) and hydrogen (H2)

Fe(s) + HCl(aq) ==> FeCl2 + H2

It isn't balanced.

To write and balance the equation for the reaction between iron (Fe) and hydrochloric acid (HCl) to form iron chloride (FeCl2) and hydrogen gas (H2), follow these steps:

Step 1: Write the unbalanced equation.
Fe + HCl → FeCl2 + H2

Step 2: Count the number of each type of atom on both sides of the equation.
On the left side, there is one iron atom (Fe) and one chlorine atom (Cl) in the hydrochloric acid. On the right side, there is one iron atom (Fe) and two chlorine atoms (Cl) in the iron chloride. Additionally, there are two hydrogen atoms (H2) on the right side.

Step 3: Balance the equation by adjusting the coefficients (numbers in front of the chemical formulas) so that the number of atoms on each side is equal.
To balance the equation, start by balancing the most complex or uncommon atoms first. In this case, we can balance the iron (Fe) first. To do this, place a coefficient of 2 in front of Fe on the reactant side:
2Fe + HCl → FeCl2 + H2

Now, both sides have two iron atoms.

Next, balance the chlorine (Cl) atoms. On the right side, there are two chlorine atoms in FeCl2. To balance this, place a coefficient of 2 in front of HCl on the left side:
2Fe + 2HCl → FeCl2 + H2

Now, both sides have two chlorine atoms.

Lastly, balance the hydrogen (H) atoms. On the right side, there are two hydrogen atoms in H2. To balance this, place a coefficient of 3 in front of H2 on the left side:
2Fe + 2HCl → FeCl2 + 3H2

Now, both sides have two hydrogen atoms.

Step 4: Double-check the balanced equation to ensure it is correctly balanced.
The final balanced equation is:
2Fe + 2HCl → FeCl2 + 3H2
