Consider the titration of a 25.0-ml sample of 0.175m ch3nh2 with 0.150 m hbr. determine each quantity. a. the initial ph b. the volume of added acid required to reach the equivalence point c. the ph at 5.0 ml of added acid d. the ph at one-half of the equivalence point

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

The question is incomplete. complete question is attached belowanswer: correct answer is option b  i.e.  solid particles  reason: filter paper has small pores, through which smaller particles can pass through. however, solid particles  have relatively larger size. hence, they are least likely to pass through.

The chlorine is the chemical property
