The Arrhenius theory established that acids and some bases: dissociate giving rise to ions.
What is the Arrhenius theory?
Arrhenius's theory was a theory of acids and bases formulated on the basis of his theory of ionization of substances in aqueous solutions.
Principles of the Arrhenius theory
- Acid substances are those that dissociate into hydrogen ions in aqueous solution.
- Basic substances are those that dissociate into hydroxyl ions in aqueous solution.
Therefore, we can conclude that the Arrhenius theory explains that the characteristic properties of aqueous solutions of acids are due to hydrogen ions.

Answer:
According to the theory, an Arrhenius acid is a substance that gives hydrogen ion, (or protons) as the only positively charged ions, when dissociated in water.
Explanation:
What this means is that acids increase the concentration of protons in water to form hydronium ions,as opposed to the idea that there aren't free hydrogen cations floating around in aqueous solution.
The Arrhenius definitions of acidity and alkalinity are restricted to aqueous solutions and refer to the concentration of dissolved ions.

Answers
Two continents have the most obvious fit of the coastlines are the east coast of South America and the west coast of Africa.
Further explanation
According to the examination of a world map it reveals a striking match between the shapes of the east coast of South America and the west coast of Africa. Attached the map which shows the west coast of Africa in 1842 and also the map of the east coast of South America. According to the picture of the west coast of Africa in 1842, we can see Sierra Leone and Freetown, where the West India Regiments arrived and departed from.
Two continents have the most obvious fit of the coastlines are the east coast of South America and the west coast of Africa, because the east coast of South America and the west coast of Africa seem to fit together like pieces of a jigsaw puzzle.
Wegener discovered that their rock layers are fit just as it clearly. All the landmasses used to be one great landmass called Pangaea. Due to plate tectonics, fire movements in the mantle of the earth, the continents are slowly through millions of years, spread farther apart.

The graph of the relationship between the rate of diffusion and molar weight is shown by option A
What is the relationship between rate of diffusion and molar weight?
Graham's law of diffusion states that the rate of diffusion is inversely related to the square root of the molar mass of a gas.
According to this relationship, under the same circumstances, lighter molecules disperse more quickly than heavier ones. It is crucial to comprehend how gases behave and how their molecular makeup affects how they travel and are distributed.
