How many moles of cu are needed to react with 3.50 moles of agno3

1.75 moles of Cu

Explanation:

Copper (Cu) reacts with silver nitrate (AgNO₃) to produce Cu(NO₃)₂ and Ag. The copper (Cu) displaces silver (Ag) in the solution.

equation of reaction

Cu + 2AgNO₃ → Cu(NO₃)₂ + 2Ag.

From the equation of reaction,

1 mole of Cu reacts with 2 moles of AgNO₃ to produce 1 mole of Cu(NO₃)₂

The stoichiometry of the reaction shows that

1 mole of Cu = 2 moles of AgNO₃

x moles of Cu = 3.50 moles of AgNO₃

x = (3.50 * 1) / 2

x = 1.75 moles of Cu

1.75 moles of Cu will react with 3.50 moles of AgNO₃
