Please kindly explain why the answer is B, it a reaction is
less than Zero?
TIF AGⓇ for a reaction is less than zero, what can you say about the value of K for the reaction? a. K<land the reaction is spontaneous under standard conditions. K >1 and the reaction is spontaneous under standard conditions. = r standard conditions. => Why if da Reaction R = 0 and the reaction is at equilibrium. is less that ou (d) <0 and...

The syringe shown at right contains nitrogen gas. The syringe
has a movable piston of mass M. At the bottom, the syringe is
closed by a valve, so that no gas may enter or leave the syringe.
(Neglect friction between the piston and the wall of the syringe.
Assume that nitrogen gas behaves like an ideal gas.) Initially the
syringe is in thermal equilibrium with an ice-water bath. The
pressure and volume of the gas inside the syringe are Pinitial...

3. A portion of a museum is required to be conditioned to 75°F/50% RH year round. Since it's a museum, the humidity must be controlled. Under design conditions, this portion of the museum has sensible cooling loads of 35,000 Btu/hr and latent cooling loads of 15,000 Btu/hir The air handler (Figure 1) designed to maintain conditions has a cooling coil, a reheat coil, and a...

Why do we measure the volume of the flask in this experiment with water rather than using the volume listed on the side? Select all correct answers that apply. Must include all correct answers for full credit.

For this problem, use the system of the spring-Earth-block system, but do not include the wall or track in your system A spring (spring constant k) is near the bottom of a frictionless loop-the-loop (radius R). The left end of the spring is secured to an immovable wall. The right end ofthe spring is used to launch a block (mass m) around the loop-the-loop 1. Explain why the track does no work on the block, even though it exerts a...
