The volume is directly proportional to the absolute temperature so the answer is A.
The mass numbers for two isotopes are unequal because they have different numbers of NEUTRONS.
Yes, you're right the answer is 0,02 moles.
A) Fe⁰ ----> Fe⁺³ +3e⁻ oxidation | *2
b) <u>Cu⁺² + 2e⁻ -----> Cu⁰ reduction |*3</u>
c) 2Fe⁰ +3Cu⁺² -----> 2Fe⁺³ + 2Cu⁰
Is there an attachment because it depends on the element.
