Question

До складу речовини входять :Карбон-80% та Гідроген-20% Знайти формулу речовини.

Answer 1

Ответ:

C₂H₆

Объяснение:

Дано:

w(C) = 80%

w(H)=20%

Рішення

n=w\Ar

n(C) = 80%\12 = 6,7

n(H) = 20%\1= 20

n(C):n(H) = 6,7:20 = 1:3

*2 = 2:6 --> C₂H₆

Answer 2

Chemical Formula of the Substance

To find the chemical formula of the substance, we need to determine the elements present and their respective ratios. According to the given information, the substance consists of 80% carbon and 20% hydrogen.

The chemical symbol for carbon is C, and for hydrogen is H. To represent the ratio of elements in a compound, we use subscripts.

Therefore, the chemical formula of the substance can be written as CH₄.

Please note that the given information is limited, and without further details, it is not possible to determine the exact compound. However, based on the given percentages, methane (CH₄) is a possible compound that fits the description.
