In a starch-type glue (e.g. a wheatpaste glue / wallpaper glue), the borax acts as a gelling agent, thereby increasing the viscosity and glue strength.
Borax also has fungicidal properties, thereby acting as a preservative against mould.
The dissolution of borax in water is an endothermic process, meaning it absorbs heat from its surroundings. This is because energy is required to break the bonds in the solid borax and allow it to dissolve in water.
It is a chemical change, because the borax reacts to the heated water.
They produce an oxidation reaction. The reaction in turn produces sulfur, which is sometimes used as a drying agent to compounds.
This is not a chemical change.
The reaction is:2 Na + 2 H2O = 2 NaOH + H2

No. It is a physical process, so it technically isn't a reaction.
When borax is added to a solution of glue and water, it creates a chemical reaction that forms a polymer known as slime. The borax acts as a cross-linker, connecting the long chains of molecules in the glue to create a stretchy and squishy substance.
It is a chemical change, because the borax reacts to the heated water.
no reaction take place between copper and water. so there is no blance equation.
When glue, water, and borax are mixed together, a chemical reaction occurs that forms a slimy substance known as slime. The borax acts as a cross-linking agent, bonding the glue molecules together to create a polymer network that gives the slime its unique texture and properties.
When you mix borax with sodium carbonate, a complex chemical reaction occurs resulting in the formation of sodium borate, water, and carbon dioxide gas. This reaction is typically exothermic, meaning it releases heat as a byproduct. Sodium borate, also known as borax, is commonly used in household cleaning products.
When borax is added to water and glue, a cross-linking reaction occurs between the borate ions and the polymer chains in the glue. This forms a network structure, creating a semi-solid gel known as slime. This reaction is reversible and can be influenced by factors such as temperature and concentration.
No, borax is not an element. It is composed of elements. Specifically, sodium borate.
They produce an oxidation reaction. The reaction in turn produces sulfur, which is sometimes used as a drying agent to compounds.
This is a neutralization reaction; the products are a salt and water.
This is not a chemical change.
