First we assume that the compound containing only C,H,and
O is combusted completely in the presence of excess oxygen, so that the only
things that can be produced are water and carbon dioxide.
From there we should back calculate the amount of
Hydrogen that is in the original sample by taking all of the hydrogen in the 0.239g
to came from the organic compound.
And since we know that the original mass of the sample
was .100g, we can also easily get a mass % H by taking the mass Hydrogen
calculated over the total original mass (.100 g)
So that:
0.239g H2O / (18.01 g/mol) = .01327 moles H20
.01327 Moles H20 * 2.02g H (per every mole H2O) = .0268g
H initially present in the sample
.0268g H / .100g sample = 26.8% H by mass

Answer:
The balance equation is
→ 
Explanation:
first, we have to make sure that the atoms are balanced
→ 
→ 
then we proceed to balance charges of each half-reaction
→ 
→

Now we multiply the half-reactions to match the number of electrons in each one
(
→
)x2
(
→
)x3
and now we do the sum of the half-reactions
2
→ 2
→ 3

→ 
note: the only atom that needed to be balanced was I
Answer: You know that monomers that are joined by condensation polymerization have two functional groups. You also know (from Part 6) that a carboxylic acid and an amine can form an amide linkage, jand a carboxylic acid and an alcohol can form an ester linkage.
Answer: When an iron nail immersed in the solution of copper sulphate than iron displaces copper from the solution of copper sulphate because iron is more reactive than copper. Therefore copper sulphate solution colour changes from blue to pale green.
