1. The three (3) main types of orbitals (s, p and d) depends on thequantum number. 2.the quantum number which gives the information about orientation of sublevel I'm space to which an election belongs is known as
pls I need correct answers

azimutal quantum number,

principal quantum number

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.
