Molecular bonds have what kind of bonds?
"Bonds" do not "have" bonds, because they are bonds themselves. The questioner may have meant to ask, "Molecular compounds have what type of bonds?", and the answer to that question is "covalent bonds".
What is a result of intermolecular forces out of covalent bonds hydrogen bonds electronegativity double bonds?
hydrogen bonds
Is adding silver nitrate to salt water a chemical change?
No, it is not. No bonds break and no bonds are created. It's only a mixing process, and that's a physical process.
What it the bond strength of hydrogen bonds?
HYDRO the whole question is to order the following inter molecular forces by increasing strength of bonds: covalent bonds ionic bonds- london dispersion forces dipolar forces hydrogen bonds metallic bonds
Is removing nail polish chemical or physical change?
This is probably an example of the sort of ambiguity which is the reason 'physical' and 'chemical' changes tend not to be mentioned outside of early science education. The exact physical make-up of the solute (nail polish) is not changed, but chemical bonds are both broken and made in this process (various intermolecular bonds). The reaction is reversible, but then, all chemical reactions are reversible, but require extra energy put into the system to reduce the entropy. Probably the best approximation would be to say it is a physical change, since all/most of the molecules involved are structurally unchanged.
Is a physical change what happens when chemical bonds break and new bonds form?
NO, that's an example of a CHEMICAL change
Are mixtures held together by chemical bonds?
No, it is held together by physical bonds. You can tell because you can separate the mixture.
When an organic solid is melted are covalent bonds broken?
no. melting is a physical change and does not involve breaking of covalent bonds
When elements form bonds it changes what?
chemical & physical properties
Scientifically what is a physical change?
A change in which no chemical bonds are broken or formed.
What is a change in the form but not nature of the substance bonds are not broken?
This is a physical change.
Why is drying considered a physical change?
No new chemical bonds need to be formed or existing chemical bonds broken during drying.
Is the dissolving salt in water a chemical or physical change?
It is a chemical change because of sodium and hydrogen bonds forming
Is a chemical bond a physical change?
The formation of chemical bonds is a chemical change.
Can be separated by physical methods?
No, compounds cannot be separated by physical methods. Because of their chemical bonds, they can only be separated by chemical methods.
What are the 2 physical properties of compounds with ionic bonds?
Some physical properties of compounds with ionic bonds are:They are generally solids at room temperature and have high melting points.They conduct electricity in an aqueous solution or molten state.
What bonds are broken and reformed during a physical process?
just think really hard
