What are two ways to reduce bias in your research? 1)Keep the research private.
2)Make sure your experiment is 3)repeatable. Remain transparent.
4) Only do the experiment once.​

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.
