Si un gaz exerce une pression de 2,00 atm lorsque 20 bouffées de particules sont présentes alors pour 4,50 atm il faut 45 bouffées car 20 bouffées = 2,00 atm donc 2*20=40 +0,5 =4,50
First structure is CH₃-CH₃. It is an alkane with two carbon atoms hence it is called ethane.
Second structure is CH₃-CH₂-CH₂-CH₃. It is an alkane with four carbon atoms hence it is called butane.
Third structure is CH₄. It is an alkane with one carbon atom hence it is called methane.
Fourth structure is CH₃-CH₂-CH₃. It is an alkane with three carbon atoms hence it is called propane.
Answer:
False
Explanation:
Reactants are starting materials and are hence located at the left hand side of the equation while products are located at the right hand side.
They all have the same number of electrons in their outer shell.
