A student wishes to determine the specific heat capacity of a certain material. After she places 5.000 g of the material at 95.10 °C to 50.0 g of water, already in the calorimeter, at 26.80 °C, the final temperature of the system is 34.70 °C. What is the specific heat capacity of the material? (specific heat capacity of water = 4.184 J/g•"C) Select one: O a. 0.183 J/g•°C O b. 0.754 J/g.°C O c. 320 J/g•°C O d. 5.47 J/g•°C One of the stages in obtaining iodine from oil brines is the conversion of aqueous iodide (as Fel,) to solid iodine in the presence of chlorine gas. The other product of this reaction is aqueous ferric chloride. Which is the correct balanced chemical equation for this process? Select one: O a. 2 Fel2(aq) + 3 Cl2íg) → 2 FeCla(aq) + 2 l2(s) O b. Felz(aq) + Cl2(g) → FeCla(aq) + \z{g) Oc. Felz(ag) + Cl2(s) → FeCla(aq) + Iz(g) O d. 3 Fel2(aq) +2 Cl2(s) → 2 Fecla(aq) + 3 I2(s)

Hello! I need answers in these three questions. Would really help a lot!

A student wishes to determine the specific heat capacity of a certain material. After she places 5.000 g of the material at 95.10 °C to 50.0 g of water, already in the calorimeter, at 26.80 °C, the final temperature of the system is 34.70 °C. What is the specific heat capacity of the material? (specific heat capacity of water = 4.184 J/g•"C) Select one: O a. 0.183 J/g•°C O b. 0.754 J/g.°C O c. 320 J/g•°C O d. 5.47 J/g•°C One of the stages in obtaining iodine from oil brines is the conversion of aqueous iodide (as Fel,) to solid iodine in the presence of chlorine gas.
