Yall better me the sun creates energy through a series of steps known as: electron-neutron chain reaction nuclear fission proton-electron chain reaction proton-proton chain reaction

- It is choice D. Proton-proton chain reaction.

Explanations:- Nuclear fusion is the reaction that is the source of energy of the Sun. In nuclear fusion, two lighter nuclei(protons) combine in a series to make helium nucleus and lots of heat is released in this process.

As it is the nuclear fusion reaction that involves the chain reaction between protons, it is known as proton-proton chain reaction.

Example:-

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.
