Here are the answers to your questions:

The chemical equation $\text{NaOH} + \text{HCl} \rightarrow \text{NaCl} + ?$ represents a neutralization reaction.

*   $\text{NaOH}$ is sodium hydroxide (a base).
*   $\text{HCl}$ is hydrochloric acid (an acid).
*   $\text{NaCl}$ is sodium chloride (a salt).

Complete the reaction.
In an acid-base neutralization, the products are a salt and water. * The missing product is water ( $\text{H}_2\text{O}$ ).
Write the word equation.
* **Sodium Hydroxide + Hydrochloric Acid $\rightarrow$ Sodium Chloride + Water**
9. Adding a base to an acid will increase the pH of the solution. Acids have a pH less than 7, and bases have a pH greater than 7. As the base is added, it neutralizes the acid, causing the pH to rise towards 7 and potentially above 7 if excess base is added.
1. Bubbles are formed during the neutralization reaction between bicarbonate of soda (sodium bicarbonate) and white vinegar (acetic acid) because carbon dioxide gas is produced as one of the products.
2. The name of the gas formed is carbon dioxide.
3. Three application examples of acid-base reactions in everyday life are:
  
  Using antacids to relieve indigestion by neutralizing excess stomach acid.
  
  Adding baking soda to acidic ingredients in baking to produce carbon dioxide, which helps dough rise.
  
  Treating acidic soil with lime (a base) to make it more suitable for plant growth.
4. Two indicators are:
  
  Red cabbage juice (a household indicator)
  
  Litmus paper (a common laboratory indicator)
5. Two safety measures when conducting an acid-base reaction experiment are:
  
  Wearing safety goggles to protect the eyes from splashes.
  
  Wearing a lab coat to protect skin and clothing from chemical spills.
