Answer: Organic compounds ending with the name (-ene) indicate that the compounds contain double bonds in their molecules.
Explanation:
Organic compounds are those molecules that contains carbon atoms (as their main element), hydrogen and oxygen which are usually present. The presence of numerous organic compounds is due to the following properties of carbon:
--> the exceptional ability of carbon atoms to catenate, that is, to combine with one another to form straight chains, branched chains or ring compounds containing many carbon atoms.
--> The ease with which carbon combines with hydrogen, oxygen, Nitrogen and halogens
--> The ability of carbon atoms to form single, DOUBLE or triple bonds.
The organic compound that has the name ending with -ene are known as the alkenes. The members of the alkene series are formed from the alkanes by the removal of two hydrogen atoms and the introduction of a DOUBLE BOND in the carbon chain. They are named after the corresponding alkanes by changing the -ane ending to -ene.
Note: the systematic name of a compound is formed from the root hydrocarbon by adding a suffix and prefixes to denote the substitution of the hydrogen atoms.
Answer:
C. To recycle molecular building blocks
Explanation:
In the shown food web, almost all organisms are the food source for the fungus. They feed on dead organic matter. Fungi breakdown dead organic matter into basic nutrients such as derivatives of C, N, O, P, K, etc. These nutrients then act as building blocks of macromolecules amino acids, carbohydrates, fats, nucleic acids required for the biogeochemical functioning of the food web.
PS: Fungi work as primary decomposers in an ecosystem like bacteria.
Answer:
Explanation:
The dilution formula is
s₁ v₁ = s₂ v₂
s₁ = .0043
v₁= 2 mL
v₂ = 100 mL
s₂ = ?
putting the values
.0043 x 2 = s₂ x 100
s₂ = .000086 = 86.0 x 10⁻⁶
Answer:
Volume also reduced to half
Explanation:
Volume and absolute temperature are directly proportional to each others
