Answer:
The correct answer is "the Lewis concept of acids and bases".
CO2 contains one atom of carbon and two atoms of oxygen.
The molecule is called Carbon dioxide, indicating that it is covalent and that there are two oxygen present.
For example, the discovery of fossil palm tree stumps in Alaska and the unearthing of fossil alligator remains in the Arctic Circle suggested that the high latitudes were a tropical landscape 52 million years ago.

Answer:
option D = N₂ + 3H₂ → 2NH₃
Explanation:
The reaction in which the nitrogen and hydrogen are reacted to form the ammonia is true.
N₂ + 3H₂ → 2NH₃
In this reaction we can see that one molecules of nitrogen react with three molecules of hydrogen and form two molecules of ammonia.
while the other options are in correct because,
2SO₂ + O₂ → 2SO₃
In this reaction two molecules of SO₂ react with one molecule of oxygen and form two molecules of SO₃.
2H₂S + 3O₂ → 2SO₂ + 2H₂O
In this reaction two molecules of H₂S react with three molecules of oxygen and produced four molecules of product.
SnO₂ + 2H₂ → Sn + 2H₂O
This is also incorrect because three molecules of reactant form three molecules of product.
Answer:
e−(Ea/RT): the fraction of the molecules present in a gas which have energies equal to or in excess of activation energy at a particular temperature
