When do chemical reactions occur? – Quora
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the products. Poly Phosphoric acid is a rare compound with the chemical formula PCl₃. Pure liquid, pure chemical, is an important industrial chemical, used in the production of phosphites and other organophosphorus compounds. It is toxic and reacts violently with water …

Chemical reaction – Wikipedia
Chemical reactions happen at a characteristic reaction rate at a given temperature and chemical concentration. Typically, reaction rates increase with increasing temperature because there is more thermal energy available to reach the activation energy necessary for breaking bonds between atoms. Reactions may proceed in the forward or reverse direction until they go to completion or reach …

When does a chemical reaction occur? What conditions make … – Quora
To make it simple a reaction occurs when the energy of the end product is lower then the components (eg combustion). It occurs when the difference of electronegativity drives the reaction (sodium with chlorine, the first one wants to get rid of its outer electron, the chlorine needs one).

How do you know when a chemical reactions occurs?
When two molecules collide with the right orientation and sufficient force, a chemical reaction may result. Not all collisions cause reactions, however; the atoms or molecules must be able to recombine to form new compounds. Breaking bonds between atoms takes up energy, while forming new bonds releases energy.

The amazing part of this reaction is initiating crystallization. Pour supercooled sodium acetate onto a surface and it will solidify as you watch, forming towers and other interesting shapes. The chemical also is known as hot ice because the crystallization occurs at room temperature, producing crystals that resemble ice cubes. 04. of 10.
