It became thicker and its viscosity decreased and cannot flow as easily as before.
You ignite a chemical reaction by adding the borax solution to the glue mixture.
In a chemical reaction, the molecules of glue and borax combine to form a flexible, springy new substance. With rubber's vulcanization serving as a model, chemical cross-linking has been extensively employed to change the physical properties of polymeric materials.
Chemical links between polymer chains provide a substance with a more solid structure and perhaps a better-defined shape. It thickened and lost viscosity, making it more difficult to flow than it once could.

Molecular solids do not ionize into several particles while ionic solids do (to some extent). Since Freezing-point depression is a colligative property, caused by the presence of particles of non-volatile solute (and not on their chemical nature), ionic solids have a multiplicative effect on the change in temperature per unit - i.e. the van't hoff constant, i<span>.

Answer:
There stable oxidation state is +3.
And they have only three energy levels
Answer:
negative but dont quote me on that
Explanation:
The extraction of metal usually makes use of the method of precipitation in which a reagent is added which is able to precipitate the required metal in its pure form without impurities.
<h3>What is extraction?</h3>
The process of extraction has to do with the removal of a substance from another. It is usually the way that pure substances are obtained in chemistry. The question is incomplete but I will try to give a general idea.
The extraction of metal usually makes use of the method of precipitation in which a reagent is added which is able to precipitate the required metal in its pure form without impurities. We can not make numerica;l calculatiosn as the values are missing.
