Answer the following questions regarding this chemical reaction: Cu(s) + HNO3(aq) --> Cu(NO3)2(aq) + H2O(l) + NO2(g) c. If you want to produce 100.0 g of Cu(NO3)2, how much volume of HNO3 is needed? Density of HNO3 is 1.51 g/cm3. Give your answer in mL. Use the correct number of significant figures.

Predict the reactants of this chemical reaction. That is, fill in the left side of the chemical equation. Be sure the equation you submit is balanced. (You can edit both sides of the equation to balance it, if you need to.) Note: you are writing the molecular, and not the net ionic equation. → NaCIO, (aq) + H₂O(1) X ローロ Ś

In the following reaction, how many grams of silver can be produced from 49.1 g copper? Cu(s) + 2AgNO3(aq) ® 2Ag(s) + Cu(NO3)2(aq)

A student precipitates 397.1 g lead (11) iodide (Pbl2) in the reaction below. Upon careful calculation, the student determines obtaining a 84.0% yield. What was the theoretical yield of grams of lead (11) iodide (Pbl2) that should have been used? Pb(NO3)²(aq) +2KI (aq) → Pbl2(s) + 2KNO³(aq) percent yield = actual yield/ theoretical yield x 100
