What does a covalent bond involve?
involves: sharing a pair of electrons between atoms in a molecule.
Why Physisorption is multilayered and chemisorption is monolayered?
physisorption involves van der wall attractive forces between adsorbent and adsorbed , This may result on the accumulation of many layers of the molecules on the surface. Chemosorption involves formation of chemical bonds between adsorbent and adsorbed molecule. Adsorbent have some functional groups or atoms on its surface with unsatisfied valences, once these valences are satisfied they don't undergo bond formation with more adsorbed molecules and only single layer is formed.
Which kind of force is a dipole- dipole force?
Intermolecular attraction
What is the difference between a hydrogen molecule and HCL molecule?
spelling?
At room temperature the greatest attractive forces exist between particles of?
At room temperature, the greatest attractive forces exist between particles of
What does a covalent bond involve?

What are the attractive forces between like substances called?
The ability of like molecule to attract is called cohesive force
When a balloon pops what changes take place to the gas inside?
the attractive forces between gas molocules increase <======8
What are diple-diple forces?
Dipole forces are attractive forces between the positive end of one polar molecule and negative end of another polar molecule. These forces have strength from 5kj to 20kj per mole.
What can happen to the amount of space between molecule in gas?
In warmer temperatures, that space can/will expand, molecule movement will increase and collisions will occur. In cooler temperatures, that space can/will decrease & molecule movement will slow down.

What is atomic bonds?
a kind of force between 2 or more atoms.a chemical bond that involves sharing a pair of electrons between atoms in a molecule.
What are the characteristic of matter?
Characteristics of matter -Particles of matterare infinitely small;have space between them;are continuously moving;have attractive forces between particles;have an increase in kinetic energy with an increase in temperature.On point 4 - gas particles are considered to have no attractive forces between one another and act totally independently of one another. However, there must be some attractive forces between particles as the pressure increases and/or the temperature decreases of gas would never condense to a liquid.
Van Der Waals Forces Are Attractive Forces Between Molecules?
Van der waals forces (ie induced dipole-dipole interactions) is a weak intermolecular attraction that exist but one molecule and another whether polar or non-polar.
What is dipole-dipole coupling mechanism mean?
Dipole-dipole forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule. They are much weaker than ionic and it happens when the two molecules are close together!
How does heat affect the viscosity of a liquid?
according to the particle model, as the temp of a material increase, the attractive forces between the particles of the material decrease. As the temp decreases , the attractive forces increase. Warmer liquids flow more quickly and cooler liquuids flow more slowly. Therefore, the viscosity of a liquid DECREASES as it is HEATED, and INCREASES as it is COOLED.
