👉 Monomeniscous is a concept in chemistry and physics that refers to a compound where only one element participates in its chemical reaction. In other words, if you have two elements involved in a chemical reaction, then they are called monomenic compounds. For example, consider the following reaction between nitrogen (N) and hydrogen gas (H2): N + 3H2 → NH3 In this reaction, nitrogen acts as the reducing agent (which means it is getting reduced), while hydrogen
