Zinc is commonly found in nature in the form of the min- eral sphalerite (ZnS). A step in the smelting of zinc is the roasting of sphalerite with oxygen to produce zinc oxide: 2 ZnS(s) + 3 O2(g)→ 2 ZnO(s) + 2 SO2(g) (a) Calculate the standard enthalpy change AH° for this reaction, using data from Appendix D. (b) Calculate the heat absorbed when 3.00 metric tons (1 metric ton = 103 kg) of sphalerite is roasted under constant-pressure conditions.

A student dissolves 11.1 g of sodium hydroxide (NaOH)in 200. g of water in a well-insulated open cup. He then observes the temperature of the water rise from 22.0 °C to 36.9 °C over the course of 5.3 minutes. Use this data, and any information you need from the ALEKS Data resource, to answer the questions below about this reaction: NaOH(s) Na (aq) + OH(aq) You can make any reasonable assumptions about the physical properties of the solution. Be sure answers you calculate using measured data are rounded to 3 significant digits. → Note for advanced students: it's possible the student did not do the experiment carefully, and the values you calculate may not be the same as the known and published values for this reaction. Is this reaction exothermic, endothermic, or neither? If you said the reaction was exothermic or endothermic, calculate the amount of heat that was released or absorbed by the reaction in this case.
