Balance the following skeleton reaction and identify the oxidizing and reducing agents: Fill in all blanks with numbers so if the term is not in the equation make it 0. CrO42- (aq) + N2O(g)+ H+(aq) + OH-(aq) + H2O(l) LaTeX: \longrightarrow⟶ Cr3+(aq) + NO(g) + H+(aq) + OH-(aq) + H2O(l) oxidizing agent is (enter just the formula of the species, e. g. CrO42-,N2O, Cr3+,NO, H2O, H+, OH-) reducing agent is (enter just the formula of the species, e. g. CrO42-,N2O, Cr3+,NO, H2O, H+, OH-)

The answer for #3 is c but i don't know why

You are making a solution of calcium chloride dissolved in water. you add solid, stir, and it dissolves. you add just a spatula tip full, stir, and the solid does not dissolve. how could you describe the solutions before and after adding the spatula tip amount

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
