Use the mole ratio of CuO produced per mole of malachite to write a balanced equation for malachite decomposition reaction. Assume that CO2 is also product of the decomposition.
Malachite, Cu2CO3(OH)2, produces 2 moles Cu per mole of Malachite.
Cu2CO3(OH)2 >> CO2 + 2CuO + H20
To write a balanced equation for the decomposition reaction of malachite, we need to determine the mole ratio of CuO produced per mole of malachite. The chemical formula for malachite is Cu2CO3(OH)2. From this formula, we can see that for every 1 mole of malachite, 1 mole of CuO is produced.
The balanced equation for the decomposition reaction of malachite is:
Cu2CO3(OH)2 -> CuO + CO2 + H2O
To write a balanced equation for the decomposition of malachite, we need to determine the mole ratio of CuO produced per mole of malachite.
The molecular formula of malachite is Cu2CO3(OH)2. From this formula, we can see that there are two moles of copper(II) oxide (CuO) produced for every one mole of malachite that decomposes.
Using this mole ratio, we can now write the balanced equation:
Cu2CO3(OH)2 → 2 CuO + CO2 + H2O
In this equation, the malachite decomposes to form two moles of copper(II) oxide, one mole of carbon dioxide, and one mole of water.
