Recall that question 2 of pre-lab quiz for project 3 introduced that molarity (molar concentration) of a solution is defined as the ratio of the amount of solute in moles to the amount of solution in liters. molarity is a common unit to express solution concentration. m o l a r i t y o f a s o l u t i o n = n u m b e r o f m o l e s o f s o l u t e ( m o l ) v o l u m e o f s o l u t i o n ( l ) during the first week of this project, you need to start with preparing stock solutions for different dyes. suppose you choose to prepare the stock solution of red dye #40 by measuring 0.05 g of dye powder, and making a 100 ml dye solution with volumetric flask. what is the molarity of this stock solution (in mol/l)? (hint: convert mass of dye powder to the number of moles first using molar mass.)

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).

explanation:

d: the voltage of the secondary coil is less than that of the primary coil.

im not suree sorry if wrong

a polar bond is formed when electrons are shared unevenly between atoms
