Salt water have less cohesion than distilled water. This is because most of the atoms are already bonded to each other so there are less atoms to be able to let cohesion occur. Hope this answers the question.
Answer:
Explanation:
before the reaction you have N=2 and H=6 after the reaction you have N=2 and H=6 so yes it follows the law
1 ba+2 br——>1 babr2
u just have to make sure u have the same number of each type of atom on either side of the equation:)
Water is a polar molecule because of its shape
A physical change is when a substance experiences a change in its physical characteristics.
For instance, cutting a diamond or a piece of glass
A chemical transformation is one in which one or more new compounds are created.
Iron rusting, for instance.
Both reversible and irreversible physical change are possible.
On the other hand, chemical change is a change that can never be reversed.
a) Electrolysis of molten MgCl2 involves chemical change since new materials are created and MgCl2 cannot be recovered.
The process of electrolysis involves passing an electric current through a substance to cause a chemical change.
