Answer:

1. Oxygen Fluoride (O with F): covalent

2. Calcium Chloride (Ca with Cl): ionic

3. Sodium with Sodium (Na with Na): neither

Explanation:

1. Oxygen Fluoride (OF2)

Oxygen with Fluorine is covalent because both of these elements are <em>nonmetals</em>. Bonds that contain only nonmetals are covalent.

2. Calcium Chloride (CaCl2)

Calcium with Chlorine is ionic because there is one <em>metal </em>and one <em>nonmetal. </em>Bonds that contain one metal and one nonmetal are ionic.

3. Sodium with Sodium

Since this is not Sodium bonding with another element, it is neither ionic or covalent.

The equilibrium expression for the reaction; C(s) + O₂(g) ------->CO₂(g) is [CO2]/[C] [O2] option C.

<h3>What is the equilibrium expression?</h3>

The equilibrium expression shows how much of the reactants are converted into products. If the equilibrium constant is large and positive, most of the reactants have been converted into products.

Thus, the equilibrium expression for the reaction; C(s) + O₂(g) ------->CO₂(g) is [CO2]/[C] [O2] option C.
