The balanced chemical equation for the reaction of copper (cu) and silver nitrate (agno3) is shown below.
cu + 2agno3 mc001-1.jpg 2ag + cu(no3)2
how many moles of copper must react to form 3.50 mol of ag?
0.175 mol
1.75 mol
7.00 mol
17.0 mol

Answer : The correct option is, 1.75 mol

Solution : Given,

Moles of silver = 3.50 mole'

The balanced chemical reaction is,

From the balanced chemical reaction, we conclude that

As, 2 moles of silver obtained from 1 mole of copper

So, 3.50 moles of silver obtained from moles of copper

Therefore, the 1.75 number of moles of copper must react to form 3.50 mole of silver.

thats a little if u want the answer just look it up on google thats what i do haha : )

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
