An electrically heated home, the temperature of the ground in contact with a concrete basement wall is 12.8 C. The temperature at the inside surface of the wall is 20.0 C. The wall is 0.10 m thick and has an area of 9.0 m2. Assume that one kilowatt hour of electrical energy costs $0.10. How many hours are required for one dollar’s worth of energy to be conducted through the wall?

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.

Answerit curves up and levels out.explanationwe assume that the container contains absolutely no ammonia to begin with as it states that "nitrogen gas and hydrogen gas" react to "produce ammonia."at dynamic equilibrium, the product and reactant concentrations are equal.this means that, starting from a concentration of zero, [nh₃] must curve "up" from zero and then level out to a constant concentration.
