Balance the following equations: (c) Al(OH)₃(s) + H₂SO₄(l) → Al₂(SO₄)₃(s) + H₂O(l)

검증된 단계별 안내

Identify the number of each type of atom on both sides of the equation.

Start by balancing the aluminum (Al) atoms. There are 2 Al atoms in Al2(SO4)3, so you need 2 Al(OH)3 on the reactant side.

Next, balance the sulfate (SO4) groups. There are 3 SO4 groups in Al2(SO4)3, so you need 3 H2SO4 on the reactant side.

Balance the hydrogen (H) atoms. Count the H atoms from both Al(OH)3 and H2SO4 on the reactant side and ensure they match the number of H atoms in H2O on the product side.

Finally, balance the oxygen (O) atoms. Check that the total number of O atoms on both sides of the equation is equal.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Balancing Chemical Equations

Balancing chemical equations involves ensuring that the number of atoms for each element is the same on both sides of the equation. This is based on the law of conservation of mass, which states that matter cannot be created or destroyed in a chemical reaction. Coefficients are used to adjust the quantities of reactants and products to achieve balance.

Types of Chemical Reactions

Understanding the types of chemical reactions, such as double displacement, is crucial for balancing equations. In a double displacement reaction, two compounds exchange ions to form new compounds. Recognizing the reactants and products in the given equation helps in predicting the correct products and their states.

States of Matter in Reactions

The states of matter (solid, liquid, gas, aqueous) are important in chemical equations as they provide information about the physical state of the reactants and products. In the given equation, Al(OH)3 is a solid, H2SO4 is a liquid, and the products include a solid and a liquid. This information can influence the reaction conditions and the balancing process.

Balance the following equations: (c) Al(OH)3(s) + H2SO4(l) → Al2(SO4)3(s) + H2O(l)
