Aluminum metal can be recycled from scrap metal by melting the metal to evaporate impurities. a. Calculate the amount of heat ne
eded to purify 1.00 mole of Al originally at 298 K by melting it. The melting point of Al is 933 K. The molar heat capacity of Al is 24 J/(mol K), and the heat of fusion of Al is 10.7 kJ/mol.
The amount of heat required to purify the Al is 25.94 * 10^3 J
<h3>What is heat capacity?</h3>
The term heat capacity refers to the amount of heat required to raise the temperature of a substance by 1K. The aluminum was heated from 298 K to 933 K then it melted.
I believe the answer is: Protons and Neutrons Protons weigh 1 amu while neutrons also weigh 1 amu. I’m not sure if they are talking about how many there is.
