From the results of the solubility test, the identity of your unknown can be
placed into one of two groups, soluble or insoluble. In fact, this test allows
you to narrow down the list of potential unknowns even further. Describe
how the solubility test can be used by a clever observer to separate the
liquids in Table 1 into three different groups rather than just two.

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

The volume of helium in a blimp is 6.28 x 10^9 millimeters. the density of helium in the blimp is .1786 kilogram/meter^3. find the mass of the helium in the blimp.

Phosphoric acid is a triprotic acid ( =6.9×10−3 , =6.2×10−8 , and =4.8×10−13 ). to find the ph of a buffer composed of h2po−4(aq) and hpo2−4(aq) , which p value should be used in the henderson–hasselbalch equation? p k a1 = 2.16 p k a2 = 7.21 p k a3 = 12.32 calculate the ph of a buffer solution obtained by dissolving 18.0 18.0 g of kh2po4(s) kh 2 po 4 ( s ) and 33.0 33.0 g of na2hpo4(s) na 2 hpo 4 ( s ) in water and then diluting to 1.00 l.
