Question
**Balancing Chemical Equations**

In this exercise, you are tasked with balancing a chemical equation. The unbalanced equation provided is:

\[ \text{Si}_2\text{H}_3(s) + \text{O}_2(g) \rightarrow \text{SiO}_2(g) + \text{H}_2\text{O}(g) \]

To balance this equation, you must make sure that the number of each type of atom on the reactant side (left) is equal to the number on the product side (right).

**Instructions:**

1. **Identify Each Component:**
   - \(\text{Si}_2\text{H}_3\) - Solid silicon hydride.
   - \(\text{O}_2\) - Gaseous oxygen.
   - \(\text{SiO}_2\) - Gaseous silicon dioxide.
   - \(\text{H}_2\text{O}\) - Gaseous water.

2. **Balance the Equation:**
   Use coefficients to balance the number of atoms for each element on both sides of the equation. Coefficients can be selected by using the input panel shown:

   - Numbers (1, 2, 3, 4, etc.)
   - Chemical elements and compounds (\(\text{Si}_2\text{H}_3\), \(\text{O}_2\), \(\text{SiO}_2\), \(\text{H}_2\text{O}\))
   - States of matter: solid (s), gas (g)
   - Other symbols: plus (+), arrow (\(\rightarrow\))

3. **Equation Balancing Tools:**
   The interface provides buttons to help you construct the balanced equation.
   - Number buttons to add coefficients before each compound.
   - A "Reset" button to clear your selection and start over.
   - A "Delete" button to remove the last input.

The goal is to ensure the same number of silicon, hydrogen, and oxygen atoms are present on both sides of the equation. Adjust the coefficients until the equation is balanced.

**Note:** Balancing chemical equations is an important skill in chemistry, ensuring the conservation of mass in reactions.
