Answer:
fluorine
Explanation:
fluorine is considered the most electronegative element
2AgNO3 + Zn --> Zn(NO3)2 + 2Ag
Its a redox reaction, Zn is oxidised (0 --> 2+), Ag is reduced (1+ --> 0)
Avogadro's number represents the number of units in one mole of any substance. This has the value of 6.022 x 10^23 units / mole. This number can be used to convert the number of atoms or molecules into number of moles. We calculate as follows:
237g CCl4 (1 mol / 153.81 g ) (6.022 x 10^23 molecules / 1 mol ) = 9.28x10^23 molecules
An isotope is the vary of neutrons in an element, causing its atomic mass to change. While an ion is a charged atom that bonds to be stable.
