Plants most commonly break large rock into smaller pieces by having the plant root grow into cracks in rocks. The plant root from below the surface grows and that's how they break rocks into pieces.
The number of molecules in a mole of a substance is the same. One mole of any substance contains 6.023 x 10 raised to the power 23.
So one mole of O2 has 6.023 x 10(23) Oxygen molecules,
One mole of water contains 6.023 x 10(23) H2O molecules, and so on.

Idk 18 but here is 20
conductor-a substance that readily conducts
insulator-a substance that does not readily allow the passage of heat or sound
ammeter-an instrument for measuring electric current in amperes.
voltmeter- an instrument for measuring electric potential in volts
current-a flow of electricity which results from the ordered directional movement of electrically charged particles.
potential difference-the difference of electrical potential between two points.
ohmic resistor- resistors that have a constant resistance
non-ohmic resistor- a resistor that's resistance increases as the current increase
power-the capacity or ability to direct or influence the behavior of others or the course of events.
Answer:
Option A. The carbocation accepts a pair of electrons.
Explanation:
A carbocation is defined as a positively charged carbon, which is bound to 3 substituents. Since it has no electrons nonbonding, it only has six electrons in its valence shell. With only six electrons in its valence shell, a carbocation is a powerful electrophile (and Lewis acid) and can react with any nucleophile that is found.
Carbocations are proposed as intermediates in many organic reactions. They also work like free radicals, which are electron-deficient species.
Same as free radicals, the carbocations are stabilized by alkyl substituents.
