Given here is the equation of a chemical reaction. magnesium + oxygen ----------`gt` magnesium oxide Which of the following can be said about the equation?

Options

A. Only the products are written on the left side of the equation.
B. Only the reactants are written on the left side of the equation.
C. Both the reactants and the products are written on the left side of the equation.
D. Both the reactants and the products are written on the right side of the equation.

Answer

To analyze the given chemical reaction equation, we can break it down step by step.

### Step 1: Identify the Reactants and Products
In the equation provided:
- Reactants: Magnesium (Mg) and Oxygen (O2)
- Product: Magnesium Oxide (MgO)

### Step 2: Write the Equation
The chemical reaction can be represented as:
\[ \text{Mg} + \text{O}_2 \rightarrow \text{MgO} \]

### Step 3: Understand the Structure of the Equation
In a chemical equation:
- The left side contains the reactants (the substances that undergo the reaction).
- The right side contains the products (the substances formed as a result of the reaction).

### Step 4: Analyze the Statements
Now, let’s evaluate the statements regarding the equation:
1. "Only products are written on the left-hand side of the equation." - This is **false** because the left side contains reactants.
2. "Only reactants are written on the left side of the equation." - This is **true** since only Mg and O2 are on the left side.
3. "Products are written on the right-hand side." - This is **true** because MgO is on the right side.
4. "Reactants are written on the right-hand side." - This is **false** since reactants are on the left side.

### Conclusion
From the analysis, we can conclude that:
- The correct statements about the equation are that only reactants are written on the left side and products are written on the right side.
