HELP ME QUICK I ONLY HAVE 15 MINUTES LEFT A solution of 0.31 M Pb(NO3)2 and 0.27 M AgNO3 is formed. What will precipitate first if solid KCl is added? (Ksp of PbCl2 = 1.6 x 10-5 and Ksp of AgCl = 1.8x10-10)
KNO3
AgCl
PbCl2
AgNO3

Based on the equation and the information in the table, what is the enthalpy of the reaction?

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

Light waves are as they pass through the
