When 2 mol of aluminum is added to 3 mol of sulfuric acid solution , there are 563 kJ of heat was produced. How many much heat will be produced if 4 mol of Al and 6 mol of the acid would react? ( Review p. 113 workbook)
I need help solving this problem .Thank you
Explain why an exothermic chemical reaction both requires and releases energy. Your answer should include a description of what is occurring on the molecular level.
