We are given the number of moles:
O = 1.36 mol
H = 4.10 mol
C = 2.05 mol
To get the empirical formula, first divide everything by
the smallest number of moles = 1.36 mol. So that:
O = 1 mol
H = 3 mol
C = 1.5 mol
Next step is to multiply everything by a number such that
all will be a whole number. In this case, multiply by 2 to get a whole number
for C, so that:
O = 2 mol
H = 6 mol
C = 3 mol
Therefore the empirical formula of the compound is:
C3H6O2
A circuit is a closed loop that electrons can travel in. A source of electricity, such as a battery, provides electrical energy in the circuit. ... The appliance may, for example, provide light or heat or mechanical energy.

Fossils are great for providing evidence for an evolutionary change! Scientists can see how long life has existed on Earth by studying fossil records. Any living organism that is preserved, is considered a fossil, including plants! Fossils take 10,000 years to be formed, showing that, yes, fossil evidence supports that these cycles of evolution take quite a long time.
Hope this helps!
