Answer: the false statement is:
The only functional group possible in a hydrocarbon is the double bond
The degree to which a specified material conducts electricity, calculated as the ratio of the card density in the material to the electric field that causes the flow of current. It is the reciprocal of the resistivity.

Explanation:
As concentrated energy is used to do WORK, it becomes spread out.
The universe is made up of constant supply of energy. Energy is use to do work; the usefulness of energy is been degraded as it is been used to carry out work. For instance, the energy in petrol is used to run motor vehicles, the process result in the conversion of the chemical energy in the petrol to heat energy. The heat energy that is produced can not be easily gathered and used again, thus, the usefulness of that heat energy has been degraded.

Explanation:
The periodic table shows the atomic number and mass number of each element.
We know that the atomic number shows;
- The number of protons in the nucleus of the atom
- The number of electrons in the neutral atom of the element.
So we obtain the number of protons and electrons by looking at the atomic number shown in the periodic table.
We also know that;
Mass number = Number of protons + number of neutrons
Since number of protons = atomic number of the atom
Number of neutrons = Mass number - atomic number
Hence we obtain the number of protons by subtracting the atomic number from the mass number given in the periodic table.
