If the difference in electronegativtiy for the atoms in a bond are greater than 0.4,we consider the bond polar, if the electronegativity is less than 0.4, we consider it non polar. if there are no polar bonds, the molecule is non polar.
V=d/t
v=18m/3sec
v=6m/s
or 6 meters per second.
Answer:
An inclined plane is a machine because it makes horizontal surface that make easier for us to move objects to higher or lower surfaces.
The bond is ionic because Na+ gave Cl- an electronic.
Giving electrons is ionic and sharing is covalent.
Answer:
1)1.61molKg-1
Explanation:
we find the molality using the formula mole of solute/Kg of solvent..
