Using our example:

Here’s the breakdown of what you actually observed, the expected results, and how to check your work. leftover aluminum wire lab answer key

[ 2Al(s) + 3CuCl_2(aq) \rightarrow 3Cu(s) + 2AlCl_3(aq) ]

Before diving into the answers, it is essential to understand the scenario. The typical setup involves taking a piece of aluminum wire (often coil-shaped or flat strips) and submerging it in a solution of copper(II) chloride ($\textCuCl_2$). , meaning it releases heat, often making the

The reaction is a single replacement (redox) reaction where aluminum displaces copper:

From equation: 3 mol CuCl₂ reacts with 2 mol Al [ 0.0372 , \textmol CuCl_2 \times \frac2 , \textmol Al3 , \textmol CuCl_2 = 0.0248 , \textmol Al ] The typical setup involves taking a piece of

Molar mass Al = 26.98 g/mol [ 0.0248 \times 26.98 = 0.669 , \textg Al reacted ]
