Question

identify the substances that are oxidised and the substances that are reduced in following reaction cuo+h2---->cu+ h2o​

Answer 1

AnswEr:

Given chemical equation:

$\sf{CuO\:+\:H_2\:\longrightarrow\:Cu\:+\:H_{2} O}$

Here,

★ oxidation of Hydrogen ( $\sf{H_2}$ ) occur.

★ reduction of Copper oxide ( $\sf{CuO}$ ) occur.

★ Reducing agent is Hydrogen ( $\sf{H_2}$ ).

★ Oxidising agent is Copper oxide ( $\sf{CuO}$ ).

$\rule{200}2$

Oxidation means :

• Addition of oxygen.
• removal of hydrogen
• loss of electrons.

Reduction means :

• Removal of oxygen.
• Addition of hydrogen.
• Gain of electrons.
