Question

which of the following best describes this equation?
mg + o₂ → mgo
the equation is not balanced because there are different substances on each side.
the equation is balanced because the product is composed of both of the reactants.
the equation is not balanced because there are more atoms of oxygen in the reactants than there are in the product.
the equation is balanced because there are the same number of molecules in the reactants as there are in the product.
mrs. bio was doing dishes in the kitchen.
dr. earth was making photocopies in the library.
the victim did not have a venomous bite.
the victims toe was not stubbed.

Explanation:

Step1: Count atoms on each side

For \(Mg + O_2
ightarrow MgO\), on the left - hand side (reactants): \(Mg = 1\), \(O=2\). On the right - hand side (products): \(Mg = 1\), \(O = 1\).

Step2: Analyze imbalance

Since the number of oxygen atoms is different on both sides (\(2\) in reactants and \(1\) in products), the equation is not balanced.

Answer:

The equation \(Mg + O_2
ightarrow MgO\) is not balanced because there are more atoms of oxygen in the reactants than there are in the product.
