Yes, carbon dioxide gas will change acidified potassium dichromate solution from orange to green due to the reduction of the dichromate ion to chromium (III) ions in the presence of reducing agents like carbon dioxide.
Sulfur dioxide gas passed through an acidic dichromate solution turns the solution from orange to green.
When acidified potassium dichromate is reacted with ethanol, the dichromate ion (Cr2O7^2-) is reduced to chromium(III) ion (Cr^3+). This reaction results in the formation of green chromium(III) sulfate (Cr2(SO4)3), with ethanol being oxidized to acetic acid.
When acidified potassium dichromate (K2Cr2O7) reacts with hydrogen sulfide (H2S), it forms chromium(III) sulfide (Cr2S3), sulfur dioxide (SO2), and water (H2O). The orange dichromate solution turns green as Cr2S3 is formed. This reaction is often used as a test for the presence of hydrogen sulfide gas.
The crystals are Red and makes a Red Orange solution, when applied to wood the wood turns a light after about 30 minutes. You can see the crystals on the website of Internationalviolin.com. GR.

The aqueous acidified potassium dichromate(VI) solution turns from orange to green.
The change in color of acidified potassium dichromate from orange to green indicates the reduction of chromium (VI) to chromium (III). This can happen when a reducing agent is introduced to the solution, causing the oxidation state of chromium to decrease and the color to change.
Sulfur dioxide gas passed through an acidic dichromate solution turns the solution from orange to green.
When acidified potassium dichromate is reacted with ethanol, the dichromate ion (Cr2O7^2-) is reduced to chromium(III) ion (Cr^3+). This reaction results in the formation of green chromium(III) sulfate (Cr2(SO4)3), with ethanol being oxidized to acetic acid.
When ethanol is oxidized with acidified KMnO4 solution, it undergoes complete oxidation to form ethanoic acid (acetic acid). The purple KMnO4 solution is reduced to green Mn2+ ions in the process.

by the burning of ammomium dichromate it gave a dark green colour
The green color is due to the formation of chromium(III) ion, Cr3+, from the reduction of chromium(VI) ion, Cr2O72-. This reduction is caused by the ferrous ions in the ferrous ammonium sulfate solution, which get oxidized to ferric ions in the process. The overall reaction involves a transfer of electrons from the iron(II) ions to the chromium(VI) ions, resulting in the observed color change.
When potassium dichromate reacts with ethanol, it undergoes a redox reaction in which the orange dichromate ion (Cr2O7^2-) is reduced to green chromium ions (Cr^3+). This colour change is from orange to green.
