Stating the difference between covalent and ionic bonding....
ionic bonds consist of the transfer of electrons, and covalent consists of the sharing of electrons.
This being said..answer choices A and B are out of the picture.
Thus, answer choice C is your answer.
Involve the attraction of opposite charges;require same amount of energy to break their bonds.
Answer:
Molecules are speeding up during boiling
Explanation:
According to the kinetic theory of matter, matter exists in three states; solid, liquid and gas. In the solid state, the molecules of a substance are in fixed positions, the can only vibrate but can not translate. In the liquid state, the molecules acquire a greater degree of freedom and can translate in addition to vibration and rotation. In a gas the molecules are infinitely free and translate at high velocities.
Arrow 1 shows a phase change from liquid to gas. This occurs during boiling. This phase change is possible because the liquid molecules acquire energy in the form of heat supplied during boiling thereby making the molecules of the liquid to speed up their motion and escape the liquid surface as vapour.
According to john dalton, elements consist of tiny particles called atoms. Atoms of each element are similar to each other. Compounds consisted of atoms of different elements combined together.
Answer:
boiling, melting, freezing, and shredding.
Explanation:
Some examples.
Are you speaking of a density gradient, in which a more concentrated solution moves below a less concentrated solution?
In that case, the more concentrated solution has the greater density, and it will gradually sink below the less concentrated solution.
In the same way, a stone will sink in water, which is less dense than the stone.
