Snap switches with nonmetallic yokes (straps) have a terminal for the equipment grounding conductor. Using this type of switch provides a means for grounding faceplates when nonmetallic boxes are used.

Snap switches with nonmetallic yokes (straps) have a terminal for the equipment grounding conductor. Using this type of switch provides a means for grounding metal face plates when nonmetallic boxes are used.

Explanation:

The snap switches that are mounted in boxes should have face plates installed in order to fully cover the opening and seat of the finished surface. Snap switches will be effectively grounded by means of connection to an equipment grounding conductor.

In addition to grounding the switch, a means must be provided to ground metal face plates.This requirement applies even if a nonmetallic face plate is used with the switch. The intent of this requirement is to ensure proper grounding of a metal face plate if at any time in the future, one is installed.

adding or remove a gaseous reactant or product changes the concentrations. if the concentration of reactant or product is increased, the system will shift away from the side in which concentration was increased (i.e. if the concentration of reactants is increased, the system will shift toward the products. if more products are added, the system will shift to form more reactants). conversely, if the concentration of reactant or product is decreased, the system will shift toward the side in which concentration was decreased (i.e. if reactants are removed, the system will shift to form more reactants. if the concentration of products is decreased, the equilibrium will shift toward the products).
