Complete the exercises below. Write a balanced equation for each of the following reactions: a. Burning magnesium metal in a carbon dioxide atmosphere reduces the CO₂ to carbon. b. In photosynthesis, solar energy is used to produce glucose (C₆H₁₂O₆) and O₂ from carbon dioxide and water.
검증된 단계별 안내1
Step 1: Identify the reactants and products for each reaction. For reaction (a), the reactants are magnesium (Mg) and carbon dioxide (CO₂), and the products are magnesium oxide (MgO) and carbon (C). For reaction (b), the reactants are carbon dioxide (CO₂) and water (H₂O), and the products are glucose (C₆H₁₂O₆) and oxygen (O₂).
Step 2: Write the unbalanced chemical equations for each reaction. For reaction (a), the unbalanced equation is: Mg + CO₂ → MgO + C. For reaction (b), the unbalanced equation is: CO₂ + H₂O → C₆H₁₂O₆ + O₂.
Step 3: Balance the equation for reaction (a). Start by balancing the number of magnesium atoms, then balance the carbon atoms, and finally balance the oxygen atoms. Adjust coefficients as necessary to ensure the same number of each type of atom on both sides of the equation.
Step 4: Balance the equation for reaction (b). Begin by balancing the carbon atoms, then balance the hydrogen atoms, and finally balance the oxygen atoms. Adjust coefficients to ensure the same number of each type of atom on both sides of the equation.
Step 5: Verify that both equations are balanced by counting the number of each type of atom on both sides of the equations. Ensure that the law of conservation of mass is satisfied, meaning the total mass of reactants equals the total mass of products.

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.
Balancing Chemical Equations
Balancing chemical equations is essential to ensure that the law of conservation of mass is upheld, meaning the number of atoms of each element must be the same on both sides of the equation. This involves adjusting coefficients in front of compounds to achieve equal numbers of each type of atom, reflecting the actual stoichiometry of the reaction.
