If the Ksp of Ca3N2 is 6.06 x 10-3, how many moles of calcium nitride (s) could you dissolve in 1.589 L of solvent (assume that calcium nitride (s) dissolves in water to form Ca2+(aq) and N3- (aq))? Enter your answer with at least 3 sig figs.

Lable the reactios as single-displacement, double displacement, synthesis decomposition HCl(aq)+NaHCO3(aq)-->Co2(g)+H20(l) AgNO3(aq)+HCl(aq)-->AgCl(s)+HNO3(aq) HFe(s)+302(g)-->2Fe2)3(s)

Question 2 of 10 Construct the expression for Kc for the following reaction. 4 HCI(aq) + O:(g) = 2 H:O(1) + 2 Cl:(g) Drag the tiles into the numerator or denominator to form the expression. Kc 5 RESET [HCI] 2[HC] 4[HCI] [HCI [HCIJ* [0:] 2[0.] 4[0:] [0:F [HO] 2[HO] 4[H:O] [H.O) [HOr [CL] 2[CL) 4[CH] [CH"

(4b-102) Only using the list of ions below, form two ionic compounds that would be soluble in water, and two ionic compounds that would be insoluble in water. You should make four different compounds, but you may use ions more than once. Be sure to indicate which is which, and make sure your compounds are charge-balanced! Mg2+ Cu2+ k+ A13+ 02- PO43- CI OH For the toolbar, press ALT+F10 (PC) or ALT+FN+F10 (Mac).

QUESTION 9 (4b-301-196-3.69) A 196 gram sample of glucose (C6H1206) was used to make a 3.69 M solution. What is the volume of that solution? Show all work and give your answer with three sig figs. Note M(C6H1206) = 180.16 g/mol. QUESTION 10 (4b-401-1.53-1) An intern working in a research lab knocks over a beaker containing an important solution. The beaker originally contained 1.50 L of a 1.53 M solution, but after it spilled it only contained 1 L of solution. The intern decides to hide his mistake by refilling the beaker to contain 1.50 L again by adding pure water (not realizing that this will dilute the solution). What is the new concentration of the solution? Show all work and give your answer with three sig figs. Click Save and Submit to save and submit. Click Save All Answers to save all answers.
