Common Definition of a Pure Substance To a non-chemist, a pure substance is anything composed of a single type of material. In other words, it is free of contaminants. So, in addition to elements, compounds, and alloys, a pure substance might include honey, even though it consists of man...
In chemistry, the pure substance is a very simple concept to grasp. It’s a substance made of only one type of atom or only one type of molecule (a cluster of atoms bonded together). A pure substance can be classified as an element or a compound. An element contains only one kind of...
Pure substances: Pure substances are made from only one type of particles and a constant structure. The properties or the chemical composition of the pure substances remain the same throughout. Answer and Explanation:
Molar mass refers to the mass of one mole of a substance (which could be an element or a compound).The molar mass of an element (in terms of atom) is equal to its relative atomic mass (Ar) in grams. The molar mass of a molecular substance is equal to its relative molecular mass (...
The simplest type of hydrocarbon system to consider is that containing one component. The word component refers to the number of molecular or atomic species present in the substance. A single-component system is composed entirely of one kind of atom or molecule. We often use the word pure to...
Mg is abundant in human body and one of essential elements for many metabolic reactions, such as muscle contraction and bone metabolism. Due to the biodegradability of Mg alloys, the degradation products are soluble and non-toxic substance, which are beneficial in physiology and can effectively ...
Answer and Explanation:1 A pure silver ring is an element because it contains only silver atoms; there is no other atom. In contrast, a compound contains more than one type of... Learn more about this topic: Elements in Chemistry | Overview...

Although it is readily metabolized in small amounts by the human body, on account of it being found naturally in fruit and vegetables and therefore not rejected by the body as an alien substance, methanol toxicity arises as a result of overloading the digestive system. When this occurs, the...
