In the following chemical reaction, 2 mol of A will react with 1 mol of B to produce 1 mol of A2B without anything left over: Aluminum reacts with chlorine gas to form aluminum chloride via the following reaction: 2A + B-—А,В 2A1(s) + 3Cl2 (g)→2AIC\3 (s) But what if you're given 2.8 mol of A and 3.2 mol of B? The amount of product formed is limited by the reactant that runs out first, called the limiting reactant. To identify the limiting reactant, calculate the amount of product formed from each amount of reactant separately: You are given 28.0 g of aluminum and 33.0 g of chlorine gas. Part A 2.8 metA 1 mol A2B 2 metA = 1.4 mol A2B If you had excess chlorine, how many moles of of aluminum chloride could be produced from 28.0 g of aluminum? Express your answer to three significant figures and include the appropriate units. 3.2 motB x 1 mol A,B 1 metB = 3.2 mol A2B • View Available Hint(s) Notice that less product is formed with the given amount of reactant A. Thus, A is the limiting reactant, and a maximum of 1.4 mol of A2B can be formed from the given amounts. HẢ ? Value Units

### Understanding Limiting Reactants in Chemical Reactions

In a chemical reaction, reactants combine in specific proportions to form products. The limiting reactant is the one that is completely consumed first, limiting the amount of product formed.

**Example Reaction:**
\[ \text{2A + B} \rightarrow \text{A}_2\text{B} \]

#### Calculating Limiting Reactant

Suppose you have:
- 2.8 mol of A
- 3.2 mol of B

The balanced equation suggests 2 mol of A react with 1 mol of B to produce 1 mol of \(\text{A}_2\text{B}\).

1. **Calculate Product from A:**
   \[
   2.8 \, \cancel{\text{mol A}} \times \frac{1 \, \text{mol A}_2\text{B}}{2 \, \cancel{\text{mol A}}} = 1.4 \, \text{mol A}_2\text{B}
   \]

2. **Calculate Product from B:**
   \[
   3.2 \, \cancel{\text{mol B}} \times \frac{1 \, \text{mol A}_2\text{B}}{1 \, \cancel{\text{mol B}}} = 3.2 \, \text{mol A}_2\text{B}
   \]

Since 1.4 mol of \(\text{A}_2\text{B}\) is produced from A and 3.2 mol from B, A is the limiting reactant. Therefore, a maximum of 1.4 mol of \(\text{A}_2\text{B}\) can be formed.

### Reaction Example with Aluminum and Chlorine:

**Reaction:**
\[ \text{2Al(s) + 3Cl}_2\text{(g)} \rightarrow \text{2AlCl}_3\text{(s)} \]

**Given:**
- 28.0 g of aluminum
- 33.0 g of chlorine gas

#### Part A: Calculating Moles of \(\text{AlCl}_3\)

If chlorine is in excess, calculate the moles of \(\text{AlCl}_3\) from 28.0 g of aluminum. Express your answer to
