Liquidtight flexible nonmetallic conduit marked as has a smooth seamless inner core and cover bonded together and one or more reinforcement layers between the core and covers for layered conduit.

Read the given expression. x = number of protons − number of core electrons which of the following explains the identity of x and its trends across a period? x is the effective nuclear charge, and it remains constant across a period. x is the screening constant, and it remains constant across a period. x is the effective nuclear charge, and it increases across a period. x is the screening constant, and it increases across a period.

Which of these expressions are correct variations of the combined gas law? p1v1t2 = p2v2t1 both

Most materials are not magnetic because their magnetism has worn off. their magnetic domains are arranged randomly. they lack magnetic fields. earth’s heat has destroyed their magnetism.
