Answer:
The question is not appropriate.The correct explanation is given below.
Explanation:
- The molecule of the oxygen cannot have the water molecule but the water molecule have the molecules of oxygen, having formula of H2O.
- A molecule of oxygen is made by combining more than one atom of oxygen forming a molecule as the atoms combines to form a molecule.
- Also, the presence of number of molecules of a particular element in a compound is fixed according to the law of definite proportion which tells that:
- The atoms of elements present in a compound are in a fix ratio by mass to be called the molecule of that particular compound.
- For example: The Formula of water is H2O having 2 atoms of hydrogen and one atom of oxygen forming a ratio of 2:1 to form ONE molecule of water. If this ratio is not maintained then we cannot call it a molecule of water.
Answer: The parent chain contains 4 carbon atoms and one triple bond. it is named as butyne. The numbering is started from the end which gives the lowest number to the triple bond. Hence, the IUPAC name of the compound is 1-butyne.

One way is for <span>a landowner to gather as much information as possible about his or her private water well, to know how it works, as well as who has had the land before them. The landowner needs to see if anyone has used pesticides in the area, as it can contaminate the well water. This is the most common way. The landowner can also check to see if any other chemicals have been spilt in the area or even a gas or oil leak, as that too can cause the contamination of well water.
I hope this helps.</span>
Answer:
Todos os três cientistas classificaram os elementos de acordo com o peso atômico.
Explicação:
As características da Tabela Periódica da Tríade Dobereiner são as seguintes:
1. é uma das classificações mais antigas de elementos.
2. nesta classificação, o peso atômico de um átomo é igual à média dos outros dois pesos atômicos.
3. é baseado no peso atômico.
Características do parafuso telúrico de Chancourtois
1. É a primeira classificação baseada no peso atômico.
2. foi a primeira representação gráfica dos elementos da tabela periódica.
Características da Lei das Oitavas de Newlands
1. também organizou os elementos de acordo com o peso atômico.
2. Em uma linha há apenas sete elementos e o oitavo vem abaixo do primeiro elemento devido às mesmas propriedades físicas e químicas.
