equal moles of C8H18 and O2 are reacted to give equal no. of moles of CO2.
mole ratio of C8H18 =(1/2) x 8 = 4 moles
mole ratio of O2 = (1/25) x 4 = 0.16 moles
so, limiting reagent is O2
the no. of moles of CO2 formed = 16 x 0.16 = 2.56 moles
weight of CO2 formed (theoretical weight) = 2.56 x 44 = 112.64
Percentage yield =(practical yiel/theoretical yield) x 100 = (28.16/112.64) x100 = 25%
Answer:
Al2(SO4)3
Explanation:
3Na2SO4 + 2AlCl3 →+ Al2(SO4)3 + 6NaCl
When it switches to a lower orbital, the atom emits energy in the form of photons. Your answer is C.
Answer:
-
Explanation:
Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.
