Reaction of halide salt with silver nitrate salt reaction with agno3 naf clear liquid nacl white solid kbr yellow solid kl tan solid during chemistry lab, carl and his lab partner, mary, mixed four halide salts, one at a time, with silver nitrate. mary commented that all but one salt reacted chemically with the silver nitrate. carl asked her how she knew that a chemical reaction had occurred. what was mary's response based on evidence in this activity? a) a gas formed. b) a precipitate formed. c) the silver nitrate disappeared. d) an exothermic reaction took place.

Intro: a solid ball of radius rb has a uniform charge density ρ. part a: what is the magnitude of the electric field e(r) at a distance r> rb from the center of the ball? express your answer in terms of ρ, rb, r, and ϵ0. part b: what is the magnitude of the electric field e(r) at a distance r express your answer in terms of ρ, rb, r, and ϵ0. part c: let e(r) represent the electric field due to the charged ball throughout all of space. which of the following statements about the electric field are true? check all that apply. e(0) = 0 e(rb)=0 limr→∞e(r)=0 the maximum electric field occurs when r=0 the maximum electric field occurs when r=rb the maximum electric field occurs as r→∞.
