Answer:
it's called polimerization that's it
As the length of carbon chain increases the forces which hold the atoms also increases . Ethanol is a liquid due to higher bond energy
Answer:
speed
Explanation:
Speed is the rate at which something moves. The speed of light is faster than the speed of sound.
Answer:
Protons
Explanation:
I'm not exactly sure if this is what your question, but the number of protons is what makes an atom that atom. If you change the number of proton it is now a different atom. You change the number of electrons and get an ion or change the number of neutrons and get an isotope but you can't change the number of protons as you would be changing the elemnt.
Answer:
When two oppositely charged objects are brought near each other, a force of attraction is produced between the charges and they become attracted to each other.
If the distance between the two charges were to be increased, the force of attraction between the two charges decreases.
Explanation:
According to Coulombs law, the force of attraction or repulsion between two charges is directly proportional to the magnitude of the charges and inversely proportional to the square of distance of separation between the charges.
Also, a fundamental principle of electrostatics states that like charges repel each other whereas unlike charges attract each other.
From these two laws, it can be deduced that a force of attraction will exist between the two oppositely charged objects when they are brought close ti each other. Also, when the distance of separation between the objects is increased, the magnitude of attractive force between them decreases. This decrease is such that if the distance of separation is increased by a factor of say 2, the magnitude of attractive force decreases by a factor of the square of 2 which is 4.
