Question

Can someone help me on #3 d) and #4 b) please... g. 3. In this 3. In this experiment, you worked with all types of matter: elements, compounds, homogeneous mixtures, heterogeneous mixtures. of each type that were encountered Give examples in this lab. a) Element(s) Coppe b) Compound(s) Copper chlonde c) Homogeneous mixture(s) Co lori soluvr d) Heterogeneous mixture(s) 4. a) What ions are present in the correct copper chloride hydrate? Give the sign or and magnitude of their charges. b) Does water exist in the crystal lattice predominately as molecules of H20 or as ions of H and OH

Explanation / Answer

Q3.

Heterogeneous mixtures are those types of mixtures that will have at least two phases, that is, a mixture of solids such as crystals

CuCl2 + CuCl2*2H2O is a good example, since they are two solids which are not likely to mix in 1 phase

Q4

In th eCopper Chloride Hydrate mix... this will happen:

CuCl2*H2O(s) ---> CuCl2(aq) + H2O(l)

CuCl2(aq) = Cu+2(aq) + 2Cl-(aq)

therefore, expect:

Cu+2 and Cl- in largest amout

b)

water is most likely to dissolve and form H2O molecules in water..
