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.
WHAT IS AN IONIC BOND
kossel explained that inert gases r inert due to the electronic configuration which contains 8 electrons in their outermost shell
And other elements loss and gain electrons to form ions and to have electronic configuration same as Noble gas and to get stable

Ice floats because it is about 9% less dense than liquid water. ... The heavier water displaces the lighter ice, so ice floats to the top. One consequence of this is that lakes and rivers freeze from top to bottom, allowing fish to survive even when the surface of a lake has frozen over
Answer:17.955atm
Explanation:Pv=nrt
P= nrt/v
P= 7.25*0.08205*360/11.90
P= 214.1505/11.90
P=17.995atm
