2. Density is a physical property of a molecule that's measured as mass per unit volume. (a) Given that density is usually expressed in the units of g/cm', calculate the density of a cube of plastic
that has a mass of 2.331 g and an edge length of 1.500 cm (volume of a cube is V = 1).

(b) Draw two liquids in a graduated cylinder on a separate sheet of paper. You won't submit the drawing as
part of your answer. Liquid A has a density of 1.004 g/cm and Liquid B has a density of 0.6223 g/cm”.
Assume they don't mix. Label which liquid is on top and which liquid is on bottom, and then draw the cube
where you would expect it to be if it's dropped into the graduated cylinder with these two liquids.
Explain the location for liquid A, liquid B, and the cube in the graduated cylinder.

Many reactions take place in aqueous solution. when potential reactants are mixed, a reaction will occur if there is some driving force that favors the formation of products. it is often convenient to categorize reactions in terms of these driving forces: precipitate formation, in which an insoluble solid is formed, weak electrolyte formation, as in a neutralization reaction involving water, or transfer of electrons, as in a redox reaction. these reactions can be represented by full molecular equations, which contain all species in the reaction mixture, or by net ionic equations, which show only the species that actually undergo a change. the latter does not contain the spectator ions, which do not undergo a net change or do not take part in the reaction. part a when the following two solutions are mixed: k2co3(aq)+fe(no3)3(aq) the mixture contains the ions listed below. sort these species into spectator ions and ions that react. drag the appropriate items to their respective bins. view available hint(s) spectator ions ions that react part b what is the correct net ionic equation, including all coefficients, charges, and phases, for the following set of reactants? assume that the contribution of protons from h2so4 is near 100 %.ba(oh)2(aq)+h2so4(aq)→ express your answer as a chemical equation. view available hint(s) nothing provide feedback

Imagine you are a business executive who wants to pursue an environment policy for your company that limits pollution and uses fewer raw materials but would cost more what might be the discussion to your next broad meeting how would you make your case to your shareholders
