Respuesta :
According to the law of definite proportions, in a compound the same elements are always present in the same proportions.
On decomposition of 18.02 g of water by electrolysis, 16.0 g of oxygen and 2.02 g of hydrogen are formed. (given)
Therefore, the ratio of grams of hydrogen to grams of water is:
2.02 g : 18.02 g
So, this ratio can be used to determine the mass of water in 795 g. As:
[tex]\frac{2.02}{18.02} = \frac{x}{795}[/tex]
[tex]x = \frac{2.02 g\times{795 g}}{18.02 g} = 89.12 g[/tex]
Hence, [tex]89.12 g[/tex] of hydrogen will be formed by the electrolysis of 795 g of water.
The study of chemicals is called chemistry. There are two types of chemicals and these are acid and base.
The correct answer to the question is 795.
What is electrolysis?
- Electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction.
- Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell.
According to the law of definite proportions, in a compound, the same elements are always present in the same proportions. On the decomposition of 18.02 g of water by electrolysis, 16.0 g of oxygen and 2.02 g of hydrogen are formed.
- Therefore, the ratio of grams of hydrogen to grams of water is: 2.02 g : 18.02 g
So, this ratio can be used to determine the mass of water is 795 g. As:
[tex]\frac{2.02}{18.02} =\frac{x}{795} \\\\x= 89.12g[/tex]
Hence, the correct answer is 89.02
