Question

1. consider the following unbalanced chemical equation: mg(s) + o₂(g) → mgo(s). in this reaction, magnesium (mg) and oxygen (o₂) are the: products. reactants. solvents. catalysts. 8. in the reaction described in the previous question (mg(s) + o₂(g) → mgo(s)), the product, magnesium oxide (mgo), has chemical properties that are: identical to the properties of oxygen. different from the properties of both magnesium and oxygen. simply a physical mixture of magnesium and oxygen properties. identical to the properties of magnesium. 9. when iron (fe) reacts with hydrochloric acid (hcl)

Explanation:

1. In a chemical equation, the substances on the left - hand side that undergo a chemical change are reactants. Here, magnesium (Mg) and oxygen ($O_2$) are on the left - hand side of the equation $Mg(s)+O_2(g)

ightarrow MgO(s)$, so they are reactants.

1. A chemical compound has its own unique chemical properties. Magnesium oxide (MgO) is a new compound formed from magnesium and oxygen, and its properties are different from those of both magnesium and oxygen.

Answer:

1. B. Reactants
2. B. Different from the properties of both magnesium and oxygen.
