Question

what brings about the following changes?
a. condensation of water vapor
b. decomposition of sugar
c. rusting of iron

Answer 1

Answer:

a: Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor.

Explanation:

c: Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. ... This prevents the metal below from coming into contact with air (containing oxygen).

b: when you heat a sugar like sucrose is you are dehydrating it. The crystalline structure of sucrose breaks down and the molecules decompose into glucose and fructose and then lose water and then become isomers and polymerize to form caramel, a red-orange colored solid at room temperature.
