From the combustion of octane, the formaldehyde will be formed as this equation:
C8H18 + O2 → CH2O + H2O this is the original equation but it is not a balanced equation, so let's start to balance it:
the equation to be balanced so the number of atoms on the right side of the equation sholud be equal with the number of atoms on the lef side.
-we have 8 C atoms on left side and 1 atom on the right side so we will try putting 8 CH2O on the right side instead of CH2O
C8H18 + O2 → 8 CH2O + H2O
we have 2 O atoms on the left side and 9 atoms on the right side so we will try first to put 9 O2 instead of O2 on the left side and put 2H2O on the right side and put 16 CH2O instead of 8 CH2O to make the atoms of O are equal on both sides = 18 atoms
C8H18 + 9 O2 → 16 CH2O + 2H2O
put now we have 8 atom C on the left side and 16 atom on the right side so, we will put 2 C8H18 instead of C8H18 now we get this equation:
2C8H18 + 9O2 →16 CH2O + 2H2O
-now we have 36 of H atoms on both sides.
- and 16 of C atoms on both sides.
- and 18 of O atoms on both sides.
now all the number of atoms of O & C & H are equal on both sides
∴ 2C8H18 + 9O2 → 16 CH2O + 2 H2O
is the final balanced equation for the formation of formaldehayde
Both have a continuous light spectra the fluorescent source makes a spectra with more intense bands of mercury

Answer:
Explanation:
In this reactor, oleic and linoleic acid react with hydrogen to form stearic acid. This reactions can be represented by:
Oleic: 
Linoleic: 
Having this reactions in mind, the first thing is to determine the moles of hydrogen required:
<u>Base of caculation: 1 mol of sunflower oil</u>
For oleic acid: 
For linoleic acid: 
Applying the excess:
Nitrogen: 
<u>After the reactions</u>:
and the nitrogen is inert.
Purge stream:
Answer:
C
Explanation:
KE at B is max and PE is 0
KE at C is 0 and PE is max
so when student swings from C to B
its KE increases
and PE decreases
