In a chemical reaction Select one: a. the covalent and ionic bonds that hold elements and compounds together are broken and new bonds are formed by either new bonds are formed, nor old bonds broken c. the covalent and ionic bonds that hold elements and compounds together are broken and no new bonds are formed d. the covalent bonds and ionic bonds that hold elements and compounds together remain intact as new bonds are formed

A. The covalent and ionic bonds that hold elements and compounds together are broken and new bonds are formed.

Explanation:

A chemical reaction is a process by which one or more substances, called reactants, are transformed into other substances with different properties, called products. In a chemical reaction, the covalent and ionic bonds between the atoms that make up the reactants are broken. Then, the atoms rearrange themselves in another way, forming new bonds and giving rise to one or more different substances from the initial ones.
