The equation describes the action of hydrochloric acid (HCl) on iron (Fe). Ferric chloride (FeCl3) and hydrogen gas (H2) are the resultants. Fe + HCl => FeCl3 + H2 Let's balance this equation. 2Fe + 6HCl => 2FeCl3 = 3H2 Simple and easy. Practice is the key. Note that ferric chloride is often written iron(III) chloride.

How do you balance CH4 H2O --- H2 CO?
To balance the equation CH4 + H2O → H2 + CO, you need to change the coefficients. Start by balancing the carbon atoms - there is 1 carbon on each side so you can leave that as is. Next, balance the hydrogen atoms by adding a coefficient of 2 in front of H2 on the product side. Lastly, balance the oxygen atoms by adding a coefficient of 1 in front of H2O on the reactant side to give you CH4 + H2O → 2H2 + CO.

How would you balance the following equation Ag H2S Ag2S H2?
To balance the equation Ag + H2S → Ag2S + H2, you need to make sure that the number of each type of atom is the same on both sides of the equation. Start by adding a coefficient of 2 in front of Ag and Ag2S to balance the silver atoms. Then, balance the hydrogen atoms by adding a coefficient of 2 in front of H2. Finally, balance the sulfur atoms by adding a coefficient of 2 in front of H2S. The balanced equation is 2Ag + 2H2S → Ag2S + H2.
In the reaction HBr plus B BBr3 plus H2 which two substances would have a coefficient of 2 if the reaction were balanced?
