Question

rusting of copper. give balanced equation ​

Answer 1

$\huge\star\underline\mathtt\purple{Answer:-}$$<font color = purple>$

Cu + H2O + CO2 ➜Cu(OH) 2 + CuCO3

it is basic copper carbonate.

Answer 2

» Chemical equation of rusting of Copper -

${\pink{\boxed{Cu + H_2O + CO_2 → Cu(OH)_2 .CuCO_3</p><p></p><p>}}}$

» To make sure equation is balanced -

Number of Cu atoms on left side = 4

Number of Cu atoms on right side = 2×2 = 4

Cu is balanced.

Number of O atoms on left side = 2

Number of O atoms on right side = 2

hence, O (oxygen) is also balanced.

Hence,our equation is balanced.

» Things to be kept in mind while balancing an equation -

$\pink{Law \:of\: conservation}$ of mass should be followed. Law of conservation of mass which states that mass can neither be created nor destroyed. So both the sides of the chemical reactions have to be balanced to ensure that this law is followed.
