Answer:
The only exception is Ethyne
Explanation:
Homologous members of alkynes formed ozonide and when treated with ozone and water, then decomposed to form ketones which are then oxidized to carbon dioxide and carboxylic acids.
Ethyne( Acetylene) is an exception as it gives glyoxal as well as formic acid on reacting with ozone.
C2H2 + O3 ==> OCHCHO + HCO2H
Therefore, Ethyne is the only exception.
The chemical makeup or identity is still the same, it is likely identity if it is a one word answer. The chemical identity is identical!
I hope this helps, God bless, and have a great day.

Answer:
12.01 grams per mole
Explanation:
theres no sample or example so if theres grams of Carbon, convert it to moles using 12.01g/mol
For a hydrocarbon, the combustion reactions are the following:
C + O₂ --> CO₂
H₂ + 1/2 O₂ --> H₂O
The molar mass of CO₂ is 44 g/mol while C is 12 g/mol. Let's solve for amount of C in hydrocarbon.
Mass of C = (14.1 g CO₂)(1mol/44g)(1 mol C/1 mol CO₂)(12 g/mol) = 3.845 g C
So, that means that the mass of hydrogen is:
Mass of H = 4.4 - 3.845 = 0.555 g
Moles C = 3.845/12 = 0.32042
Moles H = 0.555/1 = 0.555
Divide both by the smaller value, 0.32042.
C: 0.32042/0.32042 = 1
H: 0.555/0.32042 = 1.732
We have to get an answer that is closest to a whole number. Let's try multiplying both with 4.
C: 1*4 = 4
H: 1.732*4 = 6.93≈7
<em>Thus, the empirical formula is C₄H₇.</em>
