Write a balanced oxidation-reduction equation showing how zinc metal reduces the ferrous ion (fe2+) , to iron metal.

Explanation:

Oxidation reaction : A reaction in which electrons are lost and there is an increase in oxidation state.

Reduction reaction : A reaction in which electrons are gained and there is a decrease in oxidation state number.

A redox reaction is one in which oxidation and reduction takes place in a single reaction.

its mg hope this

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
