Answer:
Smallest unit is called a formula unit
Forms between a metal and a nonmetal
Formed by the transfer of electrons
Good conductor when dissolved in water
Forms repeating patterns in a crystal lattice structure
Have high melting and boiling points
Explanation:
Covalent bond is formed when atoms share electrons.
Hope this helps you.
The correct answer is <span>A. The transfer of heat and energy
Sound waves, electron movement, and conservation of matter are studied by different parts of physics. Thermo is an ancient root word/prefix that is used to refer to heat. An example of that is a Thermos, which is supposed to save heat of a liquid.</span>
Answer:
False
Explanation:
False. The molecules of liquid are hold in the liquid state due to intermolecular forces or Van de Waals forces , without affecting the molecule itself and its atomic bonds (covalent bonds). When the temperature increases the kinetic energy of the molecules is higher , therefore they have more possibilities to escape from the attractive intermolecular forces and go to the gas state.
Note however that this is caused because the intermolecular forces are really weak compared to covalent bonds, therefore is easier to break the first one first and go to the gas state before any covalent bond breaks ( if it happens).
A temperature increase can increase vaporisation rate if any reaction is triggered that decomposes the liquid into more volatile compounds , but nevertheless, this effect is generally insignificant compared with the effect that temperature has in vaporisation due to Van der Waals forces.
