Balance the reaction and state the type of chemical reaction it is. Type your answers in blue bold font. 1. K + Br → KBr
2. HgO → Hg + O2
3. Na + H2O → NaOH + H2
4. CaO + H2O → Ca(OH)2
5. Al + HCl → AlCl3 + H2
6. NaCl + AgNO3 → NaNO3 + AgCl
7. H2CO3 → CO2 + H2O
8. PbCl2 + NaI → PbI2 + NaCl
9. NH4OH → NH3 +H2O

Na food processing facility, a spherical container of inner radius r1 5 40 cm, outer radius r2 5 41 cm, and ther- mal conductivity k 5 1.5 w/m · k is used to store hot water and to keep it at 100°c at all times. to accomplish this, the outer surface of the container is wrapped with a 800-w electric strip heater and then insulated. the temperature of the inner surface of the container is observed to be nearly 120°c at all times. as- suming 10 percent of the heat generated in the heater is lost through the insulation, (a) express the differential equation and the boundary conditions for steady one-dimensional heat conduction through the container, (b) obtain a relation for the variation of temperature in the container material by solving the differential equation, and (c) evaluate the outer surface tempera- ture of the container. also determine how much water at 100°c this tank can supply steadily if the cold water enters at 20°c.
