Write a summary paragraph answering the following prompt: How can fireworks help to explain Bohr’s theory of the atom. Be sure to mention the following vocabulary words in context: electron, energy levels (or shells), quantized, ground state and excited state.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.

a electronegativity decreases beacuse the size of nucleus is bigger.

the answer is option a.
