To solve the problem step by step, we will follow these procedures: ### Step 1: Write the balanced chemical equation The reaction between magnesium (Mg) and oxygen (O₂) to form magnesium oxide (MgO) can be represented by the balanced equation: \[ 2 \text{Mg} + \text{O}_2 \rightarrow 2 \text{MgO} \] ### Step 2: Calculate the moles of magnesium (Mg) To find the number of moles of magnesium, we use the formula: ...
