Answer:
65.18% is the percent yield for this reaction.
Explanation:
Moles of salicyclic acid = 
According to reaction 1 mole of salicyclic acid gives 1 mole of aspirin .
Then 0.01449 mole of salicylic acid will give :
of asprin
Mass of 0.01449 moles of aspirin :
= 0.01449 mol × 180 g/mol = 2.6082 g
Theoretical yield of aspirin = 2.6082 g
Experimental yield of aspirin = 1.7 g
The percent yield for this reaction:
65.18% is the percent yield for this reaction.
Answer:
Observe: To model how hydrogen and oxygen react to make water, type “H2+O2” into the Reactants box and “H2O” into the Products box.
As the equation is written, which element is not in balanced?
oxygen isn't balanced...
Explanation:
in reactants there is 2hydrogens and 2 oxygen
but in product there is balanced no if hydrogen bt there is only one no of oxygen
Answer:
option d oxygen nitrogen and carbon dioxide can be classified elements hope ur help
