To balance the chemical equation 3Fe+xH2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ, we must ensure that the number of atoms of each element is equal on both sides of the reaction. Balancing oxygen atoms yields x=4, which subsequently balances the hydrogen atoms as well.
To balance the chemical equation 3Fe+xH2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ, we must ensure that the number of atoms of each element is equal on both sides of the reaction. Balancing oxygen atoms yields x=4, which subsequently balances the hydrogen atoms as well.
Think of it like a recipe: to make one batch of product (Fe3тАЛO4тАЛ+4H2тАЛ), you need exactly 3 units of iron and 4 units of water; if you have fewer or more, the reaction remains incomplete or leaves leftovers.
Remember 'ATOM' - Atoms must remain the same On both sides of the chemical equation.
3Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ тАФ The fully balanced chemical equation for the reaction of iron with steam.
This is an example of a redox reaction where iron reacts with steam to form iron(II,III) oxide. According to the Law of Conservation of Mass, the mass of reactants must equal the mass of products. By placing a coefficient of 4 before H2тАЛO, we get 8 hydrogen atoms and 4 oxygen atoms on the left, matching the 8 hydrogen atoms in 4H2тАЛ and 4 oxygen atoms in Fe3тАЛO4тАЛ.
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
Balancing chemical equations involves adjusting stoichiometric coefficients until the number of atoms for every element is identical on both reactant and product sides.
Iron reacts with hot steam to produce magnetic oxide of iron (Fe3тАЛO4тАЛ) and hydrogen gas.
Ensures compliance with stoichiometric laws.
Allows for accurate calculation of reactant and product masses.
Industrial production of hydrogen gas.
Study of corrosion and oxidation of metals.
The iron oxide Fe3тАЛO4тАЛ is known as tri-iron tetroxide or ferrous-ferric oxide.
Option D (4) is correct because it satisfies both the oxygen balance (4 on left, 4 on right) and the hydrogen balance (8 on left, 8 on right).
D is correct тАФ The value of x is 4, which balances the number of oxygen and hydrogen atoms on both sides of the equation.
Always balance oxygen first in complex metal-water reactions, then balance the remaining hydrogen atoms; this usually solves the entire equation quickly.
