The reaction of silver nitrate solution with a solution of potassium sulfide produces potasium nitrate and silver sulfide precipitate. If silver sulfide typically has a 87.35 % yield, how many grams of silver sulfide would you expect to produce from the reaction of 425.0 g of silver nitrate with excess potassium sulfide?

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

hope this !

and sorry if i'm late. have a good rest of your day! : d

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

i think it's c. if you look search electronic symbol on google and then click on wiki it shows you a
