Groundwater often has low levels of dissolved oxygen because it is not continually exposed to the atmosphere. When groundwater reaches the surface, the following reaction involving soluble iron(II) can occur. What are the oxidation numbers of the elements in the product, Fe(OH);? 4FE2*(aq) + O2(g)+ 2H2O(I) + 8OH → 4Fe(OH)3(s) a. Fe = +2, 0 =-2, H = 0 b. Fe = +2, O =-1, H =-1 c. Fe = +4, O =-2, H = +1 d. Fe = +3, 0 =-1, H =+1 e. Fe = +3, 0 =-2, H = +1

You take 1.00 g of an aspirin tablet (a compound consisting solely of carbon, hydrogen, and oxygen), burn it in air, and collect 2.20 g CO2 and 0.400 g H2O. You know that the molar mass of aspirin is between 170 and 190 g/mol. Reacting 1 mole of salicylic acid with I mole of acetic anhydride (C4H6O3) gives you 1 mole of aspirin and 1 mole of acetic acid (C2H4O2). Use this information to determine the molecular formula of salicylic acid.
