If the chemist mistakenly makes 275 mL of solution instead of the 200 mL, what molar concentration of sodium nitrate will the chemist have actually prepared?
Answer in units of M.

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.

1. they vary with a higher number because boiling is way hotter than melting

just did the assignment and the answer was #1 +2 n
