Question 1

Question 2

The specific heat capacity of copper is 0.385 J g - 1 degree C -1 whereas it is 0.128 J g - 1 degree C - 1 for gold. Assume you place 100. g of each metal, originally at 25 degree C, in a boiling water bath at 100 degree C. If energy is transferred to each metal at the same rate, which piece of metal will reach 100 degree C first? In 1947 Texas City, Texas, was devastated by the explosion of a shipload of ammonium nitrate, a compound intended to be used as a fertilizer. When heated, ammonium nitrate can decompose exothermically to N2O and water. NH4NO3(S) rightarrow N2O(g) + 2H2O(g) If the heat from this exothermic reaction is contained, higher temperatures are generated, at which point ammonium nitrate can decompose explosively to N2, H2O, and O2. 2NH4NO3(S) rightarrow 2 N2(g) + 4 H2O(g) + O2 (g) If oxidizable materials are present, fires can break out, as was the case at Texas City. Using the information in Appendix J, answer the following questions. How much thermal energy is evolved (at constant pressure and under standard conditions) by the first reaction? If 8.00 kg ammonium nitrate explodes (the second reaction), how much thermal energy is evolved (at constant pressure and under standard conditions)?

Explanation / Answer

1)since specific heat of gold is less.. therefore less heat will be required for it to reach 100 degree celcius..... therefore gold will reach 100 degree celcius first 2) where is appendix J??
