Answer:
Theoretical yield = 4.09 g water.
75% yield = 3.07g water.
Explanation:
C3H8 + 5O2 ---> 3CO2 + 4H2O
Using atomic masses:
(12 *3 + 8 * 1.008) g C3H8 yield (theoretically) (4* (2*1.008 + 16) g water
44.06g C3H8 yields 72.06g water
So 2.5 g yields (72.06/44.06) * 2.5
= 4.09 g water.
If the yield is 75% then it is 4.09 * 0.75
= 3.07 g water.
Answer:
Non-metals
Explanation:
Covalent bonds usually occur between nonmetals. For example, in water (H2O) each hydrogen (H) and oxygen (O) share a pair of electrons to make a molecule of two hydrogen atoms single bonded to a single oxygen atom.
