I am really struggling with this equation question...can someone please help me???
Use the following equation to answer the question...
Heat = -1700kJ
How many grams of rust form when 453kJ of energy is released?
1700 kJ are released when 2 moles Fe2O3 are formed. So 1700/2 = 850 kJ are released for 1 mole Fe2O3 formed. How many moles Fe2O3 do you have from 453 kJ? That will be 453/850 = ??
Convert that to grams. '
Check my thinking.
