Buckthorn is a common invasive plant throughout Michigan forests. It quickly reproduces, pushing out other plants and outcompeting native plants for resources. It has invaded a local white pine forest. The Michigan DNR is looking for a solution to the problem. The solution has to last at least one year. The impact on native species is the most important factor in selecting a solution. After the impact on native species, both the cost and how long it works for are equally important. Use a decision making matrix and the rating information below to select a method for controlling this invader.

A constraint is "something that limits or controls." According to the information in the above, what is a constraint on the possible solution to the Buckthorn problem?

It must last for at least one year.

It cannot have negative impacts on native species

It cannot cost more than $3,000.

It must not require much effort.

What does a particular point on a line of a phase diagram represent? o a. the maximum temperature a substance can exist at without bonds breaking b. the pressure created by the kinetic energy of molecules at a particular temperature c. the melting point or boiling point of a substance at a specific pressure d. the conditions in which temperature and pressure have equal effects on a substance

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
