Answer:
it can't change it is that object it is not a liquid
Explanation:
Answer:
C: It is the difference between the total kinetic and potential energy in a system.
Explanation:
Answer:
the number of moles is 0.279
Explanation:
The computation of the number of moles of calcium nitrate, is shown below;
We know that
Number of moles = mass of substance ÷ molecular weight
= 45.8 g ÷ 164.088
= 0.279moles
hence, the number of moles is 0.279
We simply applied the above formula so that the correct value could come
It's between br and si so id go with br
Dipole-dipole interactions are the major intermolecular force in a sample of liquid acetone.
London dispersion and dipole-dipole forces are both present in acetone.
<h3>What kind of attraction does a dipole-dipole have?</h3>
The positive end of one polar molecule and the negative end of another polar molecule are attracted to one another by dipole-dipole forces. Strengths of dipole-dipole forces per mole range from 5 kJ to 20 kJ.
<h3>Give an example of dipole dipole interaction.</h3>
Dipole-dipole interactions are hence forces between molecules. A dipole moment can be found in any polar molecule. Hydrogen chloride (HCl) is a good example of a dipole-dipole interaction because the comparatively positive end of a polar molecule attracts the relatively negative end of another HCl molecule.
<h3>What dipole to dipole interaction is the strongest?</h3>
For instance, the strongest intermolecular force or strongest dipole dipole force is thought to be the H-F, H-N, or H-O bonding.
