The reaction of sodium is highly exothermic with water. The rate of reaction is lowered by making an ______________ .

Explanation

To solve the question regarding the reaction of sodium with water and how to lower the rate of that reaction, follow these steps:

### Step 1: Understand the Reaction
The reaction of sodium with water is highly exothermic, meaning it releases a significant amount of heat. When sodium reacts with water, it forms sodium hydroxide (NaOH) and hydrogen gas (H2), which can lead to vigorous reactions.

### Step 2: Identify the Factors Affecting Reaction Rate
The rate of a chemical reaction can be influenced by several factors, including surface area, concentration of reactants, temperature, and the presence of inhibitors or protective layers.
