Select the correct balanced equation option for the reaction Fe+H2тАЛOтЖТFe3тАЛO4тАЛ+H2тАЛ.
3Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+2H2тАЛ
2Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ
3Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ
4Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ
3Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ
The correct balanced equation is 3Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ. This follows the Law of Conservation of Mass, ensuring the number of atoms of each element is equal on both sides of the chemical equation.
The correct balanced equation is 3Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ. This follows the Law of Conservation of Mass, ensuring the number of atoms of each element is equal on both sides of the chemical equation.
Think of it like a recipe: if the final dish requires 3 units of iron and 4 units of water, you must start your kitchen prep with exactly those amounts to ensure no ingredients are left over or missing.
ABM: Atom Balance Method (Count atoms on Left and Right until they match).
3Fe+4H2тАЛOтЖТFe3тАЛO4тАЛ+4H2тАЛ тАФ Balanced chemical equation for iron rusting by steam.
The principle of atom balancing involves setting coefficients so that the reactants and products contain the same number of atoms. Starting with iron (Fe), we need 3 on the product side, so we place a coefficient of 3 before Fe. Since there are 4 oxygen atoms in Fe3тАЛO4тАЛ, we must place a 4 before H2тАЛO, which in turn requires 8 hydrogen atoms on the right, necessitating a coefficient of 4 before H2тАЛ.
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
Balancing equations is an iterative process of adjusting stoichiometric coefficients.
Iron reacts with steam at high temperatures to form magnetic iron oxide (Fe3тАЛO4тАЛ) and hydrogen gas.
Predicts exact quantitative requirements for chemical processes.
Industrial production of hydrogen gas.
Study of corrosion and oxidation processes on metallic surfaces.
The compound Fe3тАЛO4тАЛ is known as Ferroso-ferric oxide or magnetic oxide of iron.
Option A is incorrect as the hydrogen atoms are unbalanced (4 on left, 4 on right, but only 2 in product). Option B is incorrect as iron and hydrogen are unbalanced. Option D is incorrect as iron is unbalanced.
C is correct тАФ it is the only option where the number of atoms of iron (3), hydrogen (8), and oxygen (4) are equal on both sides.
In competitive exams, always check the count of the most complex molecule first; here, Fe3тАЛO4тАЛ dictates the coefficients for Fe and H2тАЛO.
