Answer:
Because the heat energy provided at the moment of melting and freezing are used up in the transformation of the state of matter!!
Thus the temperature remains the same
Answer:
<em>One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol. 3.77mol Fe ×6.022×1023atoms Fe1mol Fe =2.27×1024 atoms Fe rounded to three significant figures.</em>
At STP, 1 mol = 22.4
1 mol = 6.022 X 10^ 23
so your answer is right it is B 6.022 X 10^ 23
Answer: 5 electrons I think
Explanation:
So, the short answer is: burning is irreversible because it involves a chemical reaction, while melting is reversible because it's just a phase change.
