Leftover Aluminum Wire Lab Answer Key -

Initial Al – reacted Al = leftover Al [ 2.50 ,g - 0.669 ,g = 1.831 , \textg (theoretical leftover) ]

Use the same steps above—just plug in your own initial masses. The logic stays the same. leftover aluminum wire lab answer key

Molar mass Al = 26.98 g/mol [ 0.0248 \times 26.98 = 0.669 , \textg Al reacted ] Initial Al – reacted Al = leftover Al [ 2

Thinner wire is harder to measure accurately via displacement because the volume change in the cylinder is so small. A thicker wire provides a larger displacement, usually leading to a lower percent error. A thicker wire provides a larger displacement, usually

In this single displacement reaction, aluminum is more reactive than copper. It gives up its electrons to the copper ions, causing solid copper to precipitate out of the solution (appearing as a reddish-brown solid) while the aluminum dissolves into solution as aluminum chloride.
