When heated borax undergoes various transitions,first it loses water molecules and swells,then it turns into a transparent liquid solidifying to for a glass like structure called borax beads.

If you take borax and boiling water and make crystals is this a physical change or a chemical change?
It is a chemical change, because the borax reacts to the heated water.
What happen when borax is heated with CaO?
When borax is heated with CaO, the borax is decomposed to form sodium metaborate and calcium metaborate. This reaction is usually used in analytical chemistry to detect the presence of boron in a sample.
Give equations to represent the following reactions.(a) Borax is heated with CaO?
The chemical equation to represent the reaction between borax (Na2B4O7) and CaO (calcium oxide) when heated is: Na2B4O7 + CaO → CaB4O7 + Na2O In this reaction, borax and calcium oxide react to form calcium tetraborate (CaB4O7) and sodium oxide (Na2O) as the products.
What happens when you mix water and Borax?
they form crystals but that's only if you have a pipe cleaner and hot water and borax
What happens when borax and water mix?
they form crystals but that's only if you have a pipe cleaner and hot water and borax
What is the principle behind borax fusion test?
The bead of borax with some powdered sample is heated in a flame; the color of the bead is specific for each element and is used as a qualitative analysis.
What happen when hydrated borax is heated strongly?
On heating, borax first loses water molecules and swells up.On further heating it turns into a transparent liquid, which solidifies into glass like material known as borax bead. Na2B4O7.10H2O -----heat------>Na2B4O7------heat------>2NaBO2+B2O3 Sodium Boric metaborate anhydride
Why does borax burn green?
Borax burns green due to the presence of boron in its chemical composition. When borax is heated, the electrons in the boron atoms are excited to higher energy levels, and as they return to their original state, they emit green light. This phenomenon is known as green flame emission.
What happens when Iodine and borax are mixed?
When iodine and borax are mixed, they do not react chemically. Both substances will remain as separate entities in the mixture. Iodine is a purple-black solid, while borax is a white crystalline powder.
What happens to matter when heated?
When matter is heated it will expand
How does boiling water dissolves borax and why?
When water is heated to its boiling point, the kinetic energy of the water molecules increases, allowing them to overcome the intermolecular forces holding the borax particles together. This increased kinetic energy helps break down the ionic bonds in borax, allowing it to dissolve in the water.
