How many grams of silver chromate will precipitate when 100.0 mL f 0.500 M silver nitrate are added to 100.0 mL of 0.400 M potassium chromate? Use the following reaction (note, this is also a limiting reagent reaction)
2AgNO3 (aq) + K2CrO4 (aq) > Ag2CrO4 (s) + KNO3 (aq)
Follow significant figures rules and do not write the unit.

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.

where are the choice options?

that's what i got you can count the number of atoms
