use the following balanced equation to answer the questions: 2mg + o₂ → 2mgo how many atoms of magnesium are present?
Answer
Explanation:
Step1: Analyze the coefficient of Mg
In the equation $2Mg + O_2\rightarrow2MgO$, the coefficient of $Mg$ is 2.
Step2: Determine the number of atoms
The coefficient represents the number of moles of the substance. Since 1 mole of any substance contains Avogadro's number of atoms and here we are just looking at the number of atoms in the given chemical - equation context, the number of magnesium atoms is 2.
Answer:
2
