What is the contribution of Svante Arrhenius in chemistry?
In 1903 Svante August Arrhenius (1859–1927) received the Nobel Prize in Chemistry for his electrolytic theory of dissociation, which states that molecules of acids, bases, and salts dissociate into ions when dissolved in water.
Which of the following ideas are attributed to Swedish chemist Svante Arrhenius?
Svante Arrhenius was a Swedish chemist from the 19th century who proposed the theory of global warming, electrolytes, and panspermia. Global warming is the idea that greenhouse gases such as carbon dioxide and water vapor absorb heat and increase the temperature of the earth.
Who is father of carbon dioxide?
Joseph Black, a Scottish chemist and physician, first identified carbon dioxide in the 1750s. At room temperatures (20-25 oC), carbon dioxide is an odourless, colourless gas, which is faintly acidic and non-flammable. Carbon dioxide is a molecule with the molecular formula CO2.
What important relation did Svante Arrhenius contribute to climate science?
A hundred years ago, Swedish scientist Svante Arrhenius asked the important question “Is the mean temperature of the ground in any way influenced by the presence of the heat-absorbing gases in the atmosphere?” He went on to become the first person to investigate the effect that doubling atmospheric carbon dioxide would …

What are the criticisms of the panspermia theory?
Panspermia is a fringe theory with little support amongst mainstream scientists. Critics argue that it does not answer the question of the origin of life but merely places it on another celestial body. It was also criticized because it was thought it could not be tested experimentally.
Can active directed panspermia secure and expand life in space?
Conversely, active directed panspermia has been proposed to secure and expand life in space. This may be motivated by biotic ethics that values, and seeks to propagate, the basic patterns of our organic gene/protein life-form.
What are the main criticisms of the radiopanspermia hypothesis?
The main criticism of radiopanspermia hypothesis came from Iosif Shklovsky and Carl Sagan, who pointed out the proofs of the lethal action of space radiation ( UV and X-rays) in the cosmos.
What is the transport mechanism of panspermia?
Panspermia can be said to be either interstellar (between star systems) or interplanetary (between planets in the same star system); its transport mechanisms may include comets, radiation pressure and lithopanspermia (microorganisms embedded in rocks).
