Using the given table of electronegativity values, determine whether each bond is nonpolar covalent, polar covalent, or ionic. table: 1st column: element (f, o, cl, br, i, s) 2nd column: electronegativity (4.0, 3.5, 3.0, 2.9, 2.7, 2.6) 3rd column: element (c, se, h, al, na, k) 4th column: electronegativity (2.5, 2.5, 2.1, 1.6, 0.9, 0.8) drag the appropriate items to their respective bins. (a. bond between c and h b. bond between k and cl c. bond between na and o d. bond between br and br d. bond between c and f e. bond between na and f f. bond between h and f g. bond between f and f h. bond between al and cl i. bond between br and f) nonpolar covalent, polar covalent, ionic

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
