Question

as part of a demonstration, mr. garcia took flat copper, cu, wire, wrapped it around a pencil to make a coil, then placed the coiled copper wire into a beaker of clear silver nitrate, 2agno3, solution. after thirty minutes, gray particles collected on the copper, and the solution turned blue. the reaction is shown by the formula. what happened during mr. garcias demonstration?
a. the atoms in the silver nitrate solution and copper (ii) nitrate solution rearranged as they reacted, producing
copper particles and silver particles.
b. the atoms in the copper and silver nitrate solution rearranged as they reacted, producing silver particles and copper (ii) nitrate solution.
c. the atoms in the silver and copper (ii) nitrate solution rearranged as they reacted, producing copper particles and silver nitrate solution.
d. the atoms in the silver and copper rearranged as they reacted, producing silver nitrate solution and copper (ii) nitrate solution.

Explanation:

In a chemical reaction, atoms are rearranged. In the reaction \(Cu + 2AgNO_3
ightarrow Cu(NO_3)_2+2Ag\), copper (\(Cu\)) reacts with silver nitrate (\(AgNO_3\)). The atoms of copper and silver in the reactants (copper and silver nitrate) are rearranged to form products (copper (II) nitrate and silver).

Answer:

D. The atoms in the silver and copper rearranged as they reacted, producing silver nitrate solution and copper (II) nitrate solution.
