Answer:
the four types of chemical weathering are:
oxidation
hydrolysis
hydration
carbonation
The synthesis of diphenylacetylene from mesostilbene dibromide includes next reactions:
• Bromination of stilbene-it is the reaction of electrophilic adition and bromonium ion is formed as intermedier (meso compound is the product).
• Bimolecular elimination-strong base is used in this reaction (takes away the H) and pi bond is formed.
Answer:
Carbohydrates
Explanation:
Carbohydrates are made up of carbon, hydrogen, and oxygen make up carbohydrates. These biomolecules are the primary sources of energy of living things, including humans. They are found in living organisms in the form of sugars, fibers, and starches. There are different types of carbohydrates like monosaccharides, disaccharades, and polysaccharide.
This supports the continental drift idea by example: a fossil animal was in one continent and then you find it in another. This is splitting the continents.
<span>Lamarck proposed that by selective use or disuse of organs, organisms acquired or lost certain traits during their lifetime. Then passed onto offspring-leading to change in species.</span>
