Quiz: HW 13
An Ideal Gaseous Reaction Occurs At A Constant Pre.. |.
Question 1
0.3 pts
The thermite reaction, used for welding iron, is the reaction of Fe304 with Al.
8 Al (s) + 3 FegO4 (s) - 4 Al203 (s) + 9 Fe (s) AH = -3350 kJ
Because this large amount of heat cannot be rapidly dissipated to the surroundings, the reacting
mass may reach temperatures near 3000 C. How much heat (in kJ) is released by the reaction of
14.8 g of Al with 75.7 g of Fe304?
Enter your numerical answer in units of kJ.
Question 2
0.2 pts
Nitromethane (CH3NO2) burns in air to produce significant amounts of heat.
4 CH3NO2 (1) + 3 02 (g) - 4 CO2(g) + 6 H20 (0 + 2 N2(g), AHrxn =-2836 kJ
If 1,869 kJ of heat are produced from the burning of nitromethane, how many grams of
nitromethane were burned?
Enter your numerical answer in units of grams.
