what
is result between glucose and sodium hydroxide
chemical reaction between copper oxide and glucose
yes because the glucose molecules contain available reactive carbonyl groups- ketones or aldehydes which lose electrons (hence- reducing) to ions in the copper sulfate in Benedict's solution. a reaction between the ions and oxygen occur to create cuprous oxide which makes a brick red colour
Respiration involves reaction between oxygen and glucose. This is what forms carbon dioxide.
ethanal
Not if the solution contained only glucose and water.
In the presence of sodium hydroxide gluconic acid is converted to sodium gluconate. Glucose first turns yellow, then brown and finally resinifies.
chemical reaction between copper oxide and glucose
The reaction between glucose and oxygen is not spontaneous. This can be demonstrated by a container of glucose sitting on a shelf, not oxidizing.
nothing
Sodium hydroxide react with the glucose in the presence of oxygen and methylene blue.Glucose ix oxidized by oxygen to gluconic acid; gluconic acid react with sodium hydroxide to form sodium gluconate.Methylene blue is reduced to a colorless leuco-derivate.

water
The starch indicator solution will diffuse out of the bag (cell) into the beaker, changing the color of the starch solution to a blue, purple, or black color (assuming that it's iodine). The color of the indicator solution inside the bag will not change, because only the glucose can diffuse into the bag, but the starch cannot diffuse into the bag.

Its a mixture!
