QUESTION 25 Will the following solutions produce a precipitate when combined? If so, the precipitate(s) would be Potassium lodide (aq) and Sodium Chloride (aq) Yes, there would be precipitation and the precipitate would be Potassium Chloride. Yes, there would be precipitation and the precipitate would be Sodium lodide. Yes, there would be precipitation and the precipitate would be Potassium lodide. O No, there would not be any precipitate formed.​

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.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
