51. (a) The equations for two chemical reactions shown below are not balanced. Balance the equations by writing the appropriate coefficients in front of the formulas in the equations.
(b) Write balanced equations for the chemical reactions described below. Writ the net ionic equation where appropriate.
(i) A precipitate forms when the aqueous solution of iron(III) nitrate and sodium sulfide are mixed.
(ii) Hydrogen peroxide (H2O2) decomposes to water and oxygen gas in the presence of manganese dioxide catalyst.
(iii) The reaction between ammonia (NH3) gas and chlorine gas produces solid ammonium chloride and nitrogen trichloride liquid.

53. The thiosulfate anion (S2O3^2-) reacts with Iodine (I2) in aqueous solution. Iodine is reduced to iodide (I-) is oxidized to tetrathionate (S4)6^2-). (see attached file for equations)

56.A titration experiment was carried out to determine the percentage of sodium hydroxide (NaOH) in a commerical drain cleaner. A sample of drain clear (0.51488g) was dissolved in water to prepare a 50 mL solution. This was titrated with 0.2039 mol L^-1 aqueous hydrochloric acid (HCl) and the volume required to neutralise the NaOH in the solution was 23.67mL. (see attached file for equations)

Comparing and contrasting the processes of photosynthesis to aerobic cellular respiration

I must complete the chart below and I am having a very hard time figuring out the solutions for both photosynthesis and cellular respiration. I need help understanding the processes of photosynthesis and respiration so I can figure this out. I do not need you to fill in the chart for me but please explain the two processes so I can figure out what the answers are myself.
