Question

How much heat is given off to the surroundings when 7 g of aluminum reacts according to the following equation? Express your answer correctly rounded to two decimal places.

2 Al + Fe2O3  Al2O3 + 2 Fe ΔH°rxn = -849 kJ.

 kJ

If all of the heat generated by the reaction was absorbed by one liter of room temperature water, what would be the highest temperature the water could reach? Express your answer correctly rounded to two decimal places.

 °C

While writing this question, I had to take into account that the final temperature reachable in the previous question could not exceed the boiling point of water. Given this information, what is the highest whole number amount of aluminum that could have been used for this question? Enter only a number for your answer.
