One mole of hydrozine loses 10 moles of electrons.If all the hydrogen content is present in the product, the oxidation number of hydrogen in product is +x. What is value of x.

Answer»

Solution :Chemical formula of hydrazine is `H_(2)-NH_(2)`
Oxidation NUMBER of each N is -2
`2 XX 02 overset("loss of 10e"^(-1))to ?`
`or 1 x -2 overset("loss of 5e"^(-1))to ?`
Oxidation number of N in the product =-2-(-5)=+3
