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:
heterogeneous
Explanation:
It's a heterogeneous mixture. Diamond is made of just one element: carbon. Each carbon atom in diamond is connected to four other carbon atoms, in a crystal that extends on and on. There are other forms of pure carbon where the atoms are bonded differently, notably charcoal and graphite.
Answer:
Freezing
Melting
Condensation
Evaporation
Sublimation
Deposition
Explanation:
From the diagram,
(1) Liquid⇒Solid (Freezing)
Freezing: This is the process by through which a substance change from liquid to solid.
(2) Solid⇒Liquid (Melting)
Melting: This is a process through which a substance change from solid to liquid
(3) Liquid⇒gas (Evaporation)
Evaporation: This is a process through which a substance change from liquid to gas.
(4) gas⇒Liquid (Condensation)
Condensation: This is a process through which a substance change from gas to liquid
(5) Solid⇒gas (Sublimation)
Sublimation: this is a process through which a subtance change from solid to gas
(6) gas⇒solid (Deposition)
Deposition: This is a process through which gas transform into solid.
Most of the energy travels trough the water
