Question

What happens during a chemical reaction

Answer 1

Answer: A new substance is created through the transformation of reactants into products.

Explanation:

A chemical reaction is a process that leads to the transformation of substances through the creation or destruction of chemical bonds between atoms, and this involves changes in energy. Reactions in which energy is released are exothermic reactions, while those that take in heat energy are endothermic. During a chemical reaction, the atoms can share electrons (and this creates bonds) or they can gain or lose electrons (creating ions)

The substance involved is called reactant, and the result substance is called product, which may have different properties from the reactants. When two ore more reactants contact each other, the bonds in the reactants are broken, and atoms are rearrange to form new bonds to make the products. So, a new substance is created through the transformation of reactants into products. No new atoms are created, and no atoms are destroyed.

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.

Answer 2

Reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products. Hope this helps!
