You dissolve 8.65 grams of lead(II) nitrate in water, and then you add 2.50 grams of aluminum. This reaction occurs: 2Al(s) + 3Pb(NO3)2(aq) → 3Pb(s) + 2Al(NO3)3(aq). What’s the theoretical yield of solid lead? Use the ideal gas resource and the periodic table. A. 5.41 g B. 11.2 g C. 19.2 g D. 28.8 g Reset

A. 5.41

Explanation:

To calculate the moles :

According to stoichiometry :

3 moles of require  = 2 moles of  

Thus 0.0261 moles of will require=  of

Thus is the limiting reagent as it limits the formation of product and is the excess reagent.

As 3 moles of give = 3 moles of

Thus 0.0261 moles of give =  of

Mass of

Thus 5.41 g of solid lead will be produced from the given masses of both reactants.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
