Lead nitrate can be decomposed by heating. what is the percent yield of the decomposition reaction if 9.9 g of pb(no3)2are heated to give 5.5 g of pbo? 2pb(no3)2( s) → 2pbo( s) + 4no2( g) + o2( g)

In an exothermic reaction the bonding energy of the product is: less than the reactants same as the reactants greater than the reactants dependent upon the presence of a catalyst
