Carbon dioxide gas is produced when sugar (glucose) reacts with cupric oxide (CuO). This reaction is a decomposition reaction that releases carbon dioxide gas along with water and elemental copper.

What bring about the following changes condensation of water vapourdecomposition of sugar and rusting of heat?

Condensation of water vapor occurs when water vapor cools and changes back into liquid form. Decomposition of sugar happens when heat breaks down the sugar molecules into simpler compounds. Rusting of iron occurs when iron reacts with oxygen in the presence of water to form iron oxide.


What changes occur when heating copper oxide and sugar?

When heating copper oxide with sugar, the copper oxide undergoes a reduction reaction where it loses oxygen atoms to form elemental copper. The sugar, on the other hand, undergoes combustion to produce carbon dioxide and water vapor. As a result, you will end up with copper metal, carbon dioxide, and water as the final products.


How do you make rocket candy with iron oxide in it?

65 : 35 Ratio of potassium nitrate to sugar (confectioners sugar works well for a powdered propellant) then take 1% of your final amount, in iron oxide RED, and add that to your mixture. (100 gram recipe = 1 gram iron oxide)


How many tons of sugar are produced every year?

Approximately 193 million metric tons of sugar are produced worldwide every year.


Why does iodine react with sugar?

Iodine reacts with sugar due to a chemical reaction called iodine starch reaction. Iodine forms a complex with starch molecules, giving a characteristic blue-black color. As sugar molecules can also form a complex with iodine, they can interfere with the reaction, leading to a color change.

Balance equation of sugar cane and cupric oxide?

The balanced chemical equation for the reaction between sugar cane (C6H12O6) and cupric oxide (CuO) is: C6H12O6 + 2 CuO → 6 Cu + 6 H2O


Maltose will reduce cupric ion in Fehling's reagent?

Yes, it will. Maltose has a free aldehyde group in its linear form, then this aldehyde reduces Cu2+ forming the cuprous oxide (CuO) which is a reddish precipitate. This is the Fehling reaction.


How does sugar change into glucose?

When sugar reacts with oxygen in your body, it produces carbondi-oxide, water and ATP.C6H12O6 + 6O2 = CO2 + 6H2O + ATP

What does Benedicts reagent do to the reducing sugar?

Benedict's test is based on Benedict's reagent, a liquid that changes color based on the sugar content of the material put in. Ketohexose acts as a reducing sugar because benedict's reagent is comprised of sodium citrate, sodium carbonate, and cupric sulfate. The cupric sulfate reacts with the ketohexose, reducing it and causing it to precipitate as cuprous oxide, which is what changes the color of the reagent and determines the sugar content.

Why does yeast create more carbon dioxide when mixed with sugar than with flour or oil?

yes. yeast reacts with sugars in the dough (or whatever you may be using) and carbon dioxide is produced. this is what fluffs up bread and creates the air holes you see in the bread. I used bread too many times in that last sentence. this also means that the yeast and the sugar isn't really a mixture - it reacts.
