When calcium oxide and coke are heated in a electric furnace, the products are carbon ii oxide and calcium carbide (CaC2), write the the equation for this reaction.
first, find the formulas for calcium oxide and coke.
You can't go anywhere at all until you know those.
Then you can write the equation, knowing that the products are CO and CaC2
The equation for the reaction between calcium oxide (CaO) and coke in an electric furnace to produce carbon dioxide (CO2) and calcium carbide (CaC2) is as follows:
CaO + 3C → CaC2 + CO2
To write the equation for the reaction between calcium oxide (CaO) and coke (carbon), we need to consider the elements involved and their respective oxidation states.
First, let's identify the elements:
- Calcium (Ca)
- Oxygen (O)
- Carbon (C)
Next, let's determine the oxidation states prior to the reaction:
- Calcium is usually +2, so its oxidation state is +2.
- Oxygen is usually -2, so its oxidation state is -2.
- Carbon is typically neutral, so its oxidation state is 0.
Now, we can write the balanced chemical equation for the reaction:
Calcium oxide (CaO) + Coke (carbon) -> Carbon dioxide (CO2) + Calcium carbide (CaC2)
The balanced equation for the reaction is:
CaO + 3C -> CO2 + CaC2
