Answer:
5.03 moles
Explanation:
Find the molar mass of C5H12 and you will get 72.17 g/mol
Next to find the number of moles, you divide 362.8 by the molar mass and you get
(362.8 g)/(72.17 g/mol)= 5.03 moles
Chlorine is more reactive than argon, because argon is not reactive at all. Chlorine only has to gain 1 valence electron
If the actual yield of sodium chloride from the reaction of 8.3 g of sodium and 4.5 g of chlorine is 6.4 g, what is the percent yield?
Answer : 2Na(s) + Cl2(g) → 2NaCl(s)
Explanation: Friend me!!!
Answer:
Ok
The Limiting reagent is Aluminum. Its not in excess. So the reaction ends once its exhausted. So all Aluminum will be used up
From the question ....
157g of Al
Find the number if reacting Moles...
M=mass/molar mass
M= 157/27
=5.81moles of Aluminum is reacting.
Now looking at the equation of reaction(Always make sure its balanced)...
2moles of Al react to produce 2 Moles of AlCl3
Their Mole ratio is equal
Since their Mole ratio is equal 2:2.... That means... That 5.81moles of AlCl3 would be produced because the mole of Al is 5.81
So We now know the Moles of AlCL3 produced
getting the Mass won't be difficult.
Again
Mole=Mass/Mm
Mass = Mole x Mm(Molar Mass)
Mass of AlCl3 = 5.81 x (27 + 35.5x3)
Note: The arithmetic done in the parenthesis is the molar mass of AlCl3
Mass of AlCl3 = 5.81 x 133.5
=775.63g of AlCl3.
