an element is a atom like titanium and a compound is like a water, glucose, alcohol and salt
Explanation:
the titanium is a element and water, glucose, alcohol, and salt those are a compound
Answer:
Energy is needed to break the bonds of H-H in H2 and Cl-Cl in Cl2
Energy is released when the H-Cl bonds form.
Explanation:
During a chemical reaction, energy is needed to break the bonds between reactants in order for reactants to recombine with each other to form products.
According to the collision theory, chemical reactions occur when reactant particles of appropriate activation energy collide with each other to form the products. This implies that energy must be absorbed in order to break Cl-Cl and H-H bonds in the reactants so that they can collide to form HCl. As the new bond is formed in the product, the excess energy absorbed by the reactants is given off.
