Which of the following is the correct count of atoms for the compound Al₂(SO₄)₃?
Al=1, S=2, O=6
Al=2, S=3, O=12
Al=2, S=1, O=4
Al=3, S=2, O=6
Answer explanation
In Al₂(SO₄)₃, there are 2 aluminum (Al), 3 sulfur (S), and 12 oxygen (O) atoms. The sulfate ion (SO₄) has 4 oxygen atoms, and with 3 sulfate ions, it totals 12 oxygen atoms. Thus, the correct count is Al=2, S=3, O=12.

According to the law of conservation of mass, if 8 grams of CH₄ react completely with 32 grams of O₂, how many grams of products are formed?
40 grams
32 grams
24 grams
16 grams
Answer explanation
According to the law of conservation of mass, the total mass of reactants equals the total mass of products. Here, 8 grams of CH₄ and 32 grams of O₂ react to form 40 grams of products (8g + 32g = 40g).

Balance the following equation: Fe₂O₃ + H₂ → Fe + H₂O
Fe₂O₃ + 6 H₂ → 2 Fe + 6 H₂O
Fe₂O₃ + 3 H₂ → 2 Fe + 3 H₂O
2 Fe₂O₃ + 6 H₂ → 4 Fe + 3 H₂O
2 Fe₂O₃ + 6 H₂ → 4 Fe + 6 H₂O
Answer explanation
To balance the equation, we need 3 H₂ for every Fe₂O₃ to produce 2 Fe and 3 H₂O. Thus, the balanced equation is Fe₂O₃ + 3 H₂ → 2 Fe + 3 H₂O, making this the correct choice.
