Suppose two chemical reactions are linked together in a way that the O₂ produced in the first reaction goes on to react completely with Mg to form MgO in the second reaction. Reaction one:
2 KClO₃ → 3 O₂ + 2 KCl
Reaction two: 2 Mg + O₂ → 2 MgO
If you start with 4 moles of KClO₃,how many moles of MgO could eventually form?

Question

Quizplus · Accepted Answer

Starting with 4 moles of KClO3, the first reaction produces 3 moles of O2 for every 2 moles of KClO3, resulting in 6 moles of O2. The second reaction shows that 1 mole of O2 reacts with 2 moles of Mg to produce 2 moles of MgO. Therefore, 6 moles of O2 would produce 12 moles of MgO.
