Question

which are the reactants in the following reaction? 2mg + o₂ → 2mgo

Explanation:

Step1: Recall reactants definition

In a chemical reaction \(aA + bB
ightarrow cC + dD\), \(A\) and \(B\) are reactants (left - hand side of the arrow).

Step2: Analyze the given reaction

For the reaction \(2Mg+O_{2}
ightarrow2MgO\), the substances on the left - hand side of the arrow (\(
ightarrow\)) are \(Mg\) (magnesium) and \(O_{2}\) (oxygen). Since \(O_{2}\) is made of \(O\) atoms, in terms of elements \(Mg\) and \(O\) are part of the reactants.

Answer:

\(Mg\) and \(O\)
