quot;A sample of aluminum chloride increased in temperature by 3.5 K when the sample absorbed 1.67 x 10^2 J of energyCalculate the number of moles of aluminum chloride chloride in this sample.quot;The molar hear capacity of aluminum chloride is 92.0 J/K molI don't know what the formula should be and what to put in, but I think it's q n C (change of temp.)
Freezer paper is heavy paper not made of aluminumThe paper gives less chance of freezer burn and you can write on it what is in it and the date it was frozenFreezer paper is also easier to remove from frozen food.
