Answer: Combustion reactions are characterized by the reaction of a substance with O2 to form one or more oxygen, often water. Combustion reactions emit heat, and they are important because most of society's energy is derived from them. Ex.: CH4 (g) + 2O2 (g) -- CO2 (g) + 2H2O (g)

Answer. Methane molecule is made up of five atoms; four of hydrogen and one of carbon. Carbon atom is sharing its 4 valence electrons with 4 hydrogen atoms each having 1 electron.
Explanation:
Dalton model of atom said that the matter is made up of smallest indivisible particle that is an atom. From which he predicted that methane molecule will be made up one carbon atom and 4 hydrogen atoms.
Quantum model of atom described the structure of atom with the help of four quantum numbers. These number explained the position, magnetic character and spin of electrons inside the atom. and further explained the sharing of electron between one one carbon and 4 hydrogen atoms.
Hence from these two models we can predict that methane molecule is made up atoms with sharing of electrons.
Answer:
Only one seven carbon hydrocarbon was produced.
Explanation:
- Alkynes are reduced completely in presence of
to produce alkanes. - Hydrogenation in presence of Pt is a simple nucleophilic addition process where
molecule adds onto an unsaturated bond. - Hept-1-yne, hept-2-yne and hept-3-yne are constitutionally isomeric to each other. Hence, after complete reduction, all three alkynes produced heptane as only product.
- So, only one seven carbon hydrocarbon was produced.
Answer:
A) coenzyme A
Explanation:
The NADH and FADH₂ are the energy rich molecules which are formed in the processes like glycolysis, TCA cycle and the fatty acid oxidation as they contain pair of electrons which have very high transfer potential.
As a result of the energy produced when these molecules transfer their electrons to the oxygen , ATP is generated by a series of electron carriers which collectively is called electron transport chain (ETC).
<u>The components of chain include Fe–S centers, Non-heme, FMN, coenzyme Q, and cytochromes .
</u>
The energy derived from the transfer of electrons is used to pump the protons across mitochondrial membrane.
As a result, an electrochemical gradient is generated which results in some energy which is then harnessed by the ATP synthase to form ATP.
