Question 1 of 6 Which two particles have opposite charges? O A. Electrons and protons B. lons and neutrons O C. Electrons and neutrons OD D. Neutrons and protons SL PLS HELP I I'm GOING TO GIVE BREINLEST

the molecules move in straight line until they collide with each other or with the walls of the container. collisions are perfectly elastic; when two molecules collide, they change their directions and kinetic energies, but the total kinetic energy is conserved.

explanation:

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.
