An example of a structure that contains amide is the nylon, paracetamol, and dimethylformamide.
<h3>What is an amide?</h3>
An amide is defined as the organic chemical compound which is a functional group that contains carbonyl group bonded to a nitrogen or any compound containing this functional group.
Typical examples of compounds that contains an amide group include the following:
- Nylon: This is a chemical compound that contains synthetic copolymer composed of secondary amides separated by two or more methylene groups.
- paracetamol, and
- dimethylformamide.

Answer: B: Iron rusts when exposed to air.
Explanation:
Answer: Substances on Earth can exist in one of four phases, but mostly, they exist in one of three: solid, liquid or gas. Learn the six changes of phase: freezing, melting, condensation, vaporization, sublimation and deposition. Intermolecular forces are forces between molecules that determine the physical properties of liquids and solids. 11.2 Vaporization and Vapor Pressure— vaporization is the conversion of a liquid to a gas (vapor), and the quantity of heat associated with this phase change is known as the enthalpy (heat) of vaporization. When kinetic energy is increasing molecules are simply moving faster. However, when the potential energy is increasing molecules are changing phases. Therefore, when the potential energy is increasing is when the molecule is changing phases. Phase changes require either the addition of heat energy (melting, evaporation, and sublimation) or subtraction of heat energy (condensation and freezing). ... Changing the amount of heat energy usually causes a temperature change.
HOpe this helps..... Stay safe and have a Merry Christmas!!!!!!!!!! :D
