- Nutritional biochemists have known for decades that acidicfoods cooked in cast-iron cookware can supply significantamounts of dietary iron (ferrous ion).(a) Write a balanced net ionic equation, with oxidation numbers,that supports this fact.(b) Measurements show an increase from 3.3 mg of iron to49 mg of iron per 1/2 -cup (125-g) serving during the slow prepa-ration of tomato sauce in a cast-iron pot. How many ferrous ionsare present in a 26-oz (737-g) jar of the tomato sauce?arrow_forwardAcetic acid is the principal ingredient in vinegar as shown; that's why it tastes sour. At equilibrium, a solution contains [CH3CO2H] = 0.0787 M and [H3 O+] = [CH3 CO2−] = 0.00118 M. What is the value of Ka for acetic acid?arrow_forwardHow many grams is one mole of potassium phosphate K2HPO4 is?arrow_forward
- What mass of citric acid (triprotic, C6H5O7H3) contains 152 mEq of citric acid?arrow_forwardA student ran the following reaction in the laboratory at 759 K: N2(g) + 3H2(g) = 2NH3(g) When she introduced 3.13×10-2 moles of N2(g) and 6.00x102 moles of H2(g) into a 1.00 liter container, she found the equilibrium concentration of NH3(g) to be 6.84×10-4 M. Calculate the equilibrium constant, K., she obtained for this reaction. K. =arrow_forwardAt what pressure in atm does ethane (C₂H₆) have a density of 37.2 g/L at 75.0 °C?arrow_forward

Write the chemical equation of the reactions, and identify which substance is reduced and which is oxidized.arrow_forwardThe ΔG°′ value for glucose-1-phosphate is -20.9 kJ/mol. If glucose and phosphate are both at 4.8 mM, what is the equilibrium concentration of glucose-1-phosphate?arrow_forwardCarbon dioxide is dissolved in blood (pH 7.4) to form a mixture of carbonic acid and bicarbonate. Neglecting free CO2, what fraction will be present as carbonic acid? Would you expect a significant amount of carbonate (CO32-)?arrow_forward
