Answer:
fossil fuel combustion
Explanation:
Fossil fuel is the source of energy that drives almost all industrial processes on the surface of earth. Burning of these fuels releases energy for use in automobiles, industries, homes e.t.c. The complete combustion of these fuels in the presence of oxygen liberates carbon-dioxide and water with heat energy.
Fossil fuels are to a large extent hydrocarbon compounds and their derivatives. They form from organisms million of years ago. When organic matter is prevented from decay in an oxic or oxygen rich environment, they are able to conserve and preserve the energy in them for a vast duration in geologic time. This preserved energy is what becomes available during combustion.
Some of the fossil fuels are oil, natural gas, coal, e.t.c.
The activity of pure substance is taken as 1 because it has no effect on the reaction. Hence the equilibrium constant of the reaction is given by: <span>Ka=[H3O+][HCO1−3]/[H2CO3]. Hope this helps :)</span>
Answer: The IUPAC name of propan-2-one and is pentan-2-one.
Explanation:
The basic rules for naming of organic compounds are :
1. First select the longest possible carbon chain. The longest possible carbon chain should include the carbons of double or triple bonds or functional group.For the number of carbon atom, we add prefix as 'meth' for 1, 'eth' for 2, 'prop' for 3, 'but' for 4, 'pent' for 5, 'hex' for 6, 'sept' for 7, 'oct' for 8, 'nona' for 9 and 'deca' for 10.
2. The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne by adding the suffix -yne and ketones by adding the suffix -one.;
3. The numbering is done in such a way that the carbon containing the functional group gets the lowest number. While writing the name, the word root is given first , followed by the position of carbon containing the functional group followed by the suffix.
The IUPAC name of propan-2-one and is pentan-2-one.
Answer:
Chemical to electrical to mechanical
Explanation:
The energy conversion going on in a battery - powered toy car is from chemical to electrical and then to mechanical energy.
According to the law of conservation of energy, energy is neither created nor destroyed but transformed from one form to another.
- A battery is a cell that is capable of producing electrical energy from chemical actions.
- This electrical energy is used to power rotors in the toy car which cause the mechanical motion of the device.
Because it's members are so different from to each other
