Astudent mixes 0.50 l of 0.0020 m ba(no3)2 solution with 0.50 l of 0.0080 m na2so4 solution. which equation shows the proper set-up to calculate molar concentration of ba2+ ions in the new solution?
(0.0020 m)(1 l) = (? m)
(0.0020 m)(0.5 l) = (? m)(1 l)
(0.0020 m)(0.5 l) = (0.0080 m)(1 l)
(0.0020 m)(0.5 l) = (0.0080 m)(0. l)

(0.0020 M)×(0.5 L) = (? M)×(1 L)

Explanation:

To find the concentration of the final solution when you concentrate or dilute a particular solution is done by using the following formula:

initial concentration × initial volume = final concentration × final volume

The question is asking about the concentration of barium ions in the final solution.

initial concentration of Ba²⁺ = 0.0020 M

initial volume = 0.50 L

final concentration = unknown (?)

final volume = volume of the initial solution + volume of the second solution

final volume =  0.50 + 0.50 = 1 L

You insert the values in the equation and you find the answer asked by the question.

c)red bank

explanation:

red bank is a borough in monmouth county, new jersey, incorporated in 1908 and located on the navesink river, the area's original transportation route to the ocean and other ports.

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
