Complete and balance the following equations, and identify the oxidizing and reducing agents. (Recall that the O atoms in hydrogen peroxide, H2O2, have an atypical oxidation state.)

(a) NO2⁻¹(aq) + Cr2O7⁻²(aq) → Cr³⁺(aq) + NO3⁻¹(aq) [acidic solution]
(b) S(s) + HNO3(aq) → H2SO3(aq) + N2O(g) [acidic solution]
(c) H2O2(aq) + ClO2(aq) → ClO2⁻¹(aq) + O2(g) [basic solution]

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)
