It seems like your question is incomplete. If you're asking about a specific item or product that is olive drab and chemically treated to change color, please provide more context. Generally, certain military uniforms or equipment may be treated with chemicals to alter color for camouflage purposes, adapting to different environments. If you provide more details, I can offer a more precise answer!
Olive drab refers to a specific shade of greenish-brown often used in military uniforms and equipment. When discussing materials that change color upon contact, you might be referring to specially treated fabrics or coatings that have been engineered to react to environmental factors, such as temperature or moisture. These treatments can cause the fabric to shift in color, enhancing visibility or indicating exposure to certain conditions. Such technologies are often used in tactical gear or outdoor clothing.
Powdering sugar does not change it chemically.
It depends on the elements used. e.g. Burn solid, black carbon in oxygen and you get CO2. The C & O have both changed chemically as they share electrons. The solid carbon has now become a gas and is no longer black. That's a physical change, brought about chemically.
