in constant, random motion. They continue in a straight line until they collide with something—usually each other or the walls of their container. Particles are point masses with no volume.

If 34.5 g of Copper reacts with 70.2 g of silver nitrate, according to the following
Vlada [557]

Answer:

44,55 can be produced.

Explanation:

First, we balanced the equation

1Cu + 2AgNO3 → 1Cu(NO3)2 + Ag

Then, we find the moles of each reagent

mol Cu = \frac{34,5g}{63,55\frac{g}{mol} } = 0,543 mol\\

mol AgNO3 = \frac{70,2g}{169,87\frac{g}{mol} } = 0,413 mol\\

Now, we find the limiting reagent from the quantities of product that can be formed from each reagent

mol AgNO3= 0,543mol Cu . \frac{2 mol AgNo3}{1 mol Cu} = 1,086 mol

mol Cu= 0,413 mol AgNO3 . \frac{1 mol Cu}{2 mol AgNO3} = 0,206 mol

1,086 moles of AgNO3 is necessary for each mole of Cu since we have 0.413 moles of Ag(NO3), the nitrate is the limiting reagent

the value of the limiting reagent determines the amount of product that is generated

∴ 0,413 mol of Ag can be produced

Ag = 0,413 mol . 107,87\frac{g}{mol} = 44,55g

Ag≈ 44,6g
