<h3>What are organic compounds?</h3>
Organic compounds can be defined as compounds containing carbon and hydrogen.
Some classes of organic compounds are:
- Alkanes
- Alkenes
- Alkanols
- Alkanals
- Alkynes
So therefore, he name of the molecule above is Ethene

Answer:
H₂O
Explanation:
Chemical equation:
C₅H₁₂ + O₂ → CO₂ + H₂O
Balanced chemical equation:
C₅H₁₂ + 8O₂ → 5CO₂ + 6H₂O
The given reaction is combustion reaction. The balance equation shows that there are equal number of moles of carbon, hydrogen and oxygen on both side of equation thus it follows the law of conservation of mass.
Combustion reaction:
The reaction in which substance react with oxygen and produced carbon dioxide and water.
Mostly hydrocarbons burns in the presence of oxygen and form carbon dioxide and water.

Answer:
FLASK B WHICH CONTAINS CO2 HAS THE HIGHEST NUMBER OF MOLECULES AS IT CONTAINS THE HIGHEST MOLECULAR MASS OF 44 G/MOL.
Explanation:
Flask A contains CH4
Flask B contaims CO2
Flask C contains N2
To know the flask containing the largest number of molecules, we find the molar mass of the molecules in the flask and the largest is the one with the highest number of the relative molecular mass.
Molecular Mass of CH4 (C = 12, H =1) = ( 12 + 1*4) g/mol
= 16 g/mol
Molecular mass of CO2 (C= 12, 0= 16) = (12 + 16*2) g/mol
= 12 + 32 g/mol
= 44 g/mol
Molecular mass of N2 (N=14) = 14 * 2 g/mol
= 28 g/mol
Hence, the flask with the largest number of molecules is the flask with the highest relative molecular mass. The highest molecular mass is 44 g/mol and it is for the gas CO2 in Flask B.
So therefore, Flask B has the highest number of molecules in it.
The answer is (4) neutron and proton. The electron has very little mass and the neutron and proton have approximately the same mass. The positron has approximately the same mass as electron. The beta particle is electron. And the alpha particle is the nucleus of He which is about the same mass as 4 protons.
