Unit $4$ Hand$-$In Assignment #$2$ This assignment covers sections $4\mathrm{.}4-4\mathrm{.}5.$ Make sure you show all states for products and remember to balance equations. When using a formula, write down the formula then substitute values with units. Your answer must have the correct units and significant figures in all of your final answers. $1.$ What is the solubility of a saturated solution of: a$.$ Ammonium chloride at $80^$C in g $/100$mL of water. $(1)$ b$.$ NH$\_3$ at $15^$C in mols$/$L water $($show your work$).(2)2.$ You mix $20$g of potassium nitrate with $100$mL of water at $20^$C$.$ Describe the solution in terms of saturation. $(1)3.$ There is more dissolved oxygen in the ocean the at greater depths when compared to dissolved oxygen at the surface. Using Henry's Law, describe this observation. $(2)4.$ State whether the following compounds are soluble or insoluble in water. $(3)$ a$.$ Sodium hydroxide Soluble in water b$.$ Ammonium acetate Soluble in water c$.$ Calcium sulfate not solvble in wate d$.$ Lead $($II$)$ chloride not scluble in water e$.$ Potassium chloride solulde in water f$.$ Calcium bromide soluide in water
