The National Association of Home Builders estimates that deducting MI premiums will save homeowners more than $1.3 billion per year so this is important stuff.
Sulfur and iron: since this is a mixture, the sulfur retains its properties (its yellow color, for example), and the iron retains its properties (its black color, for example). These properties can be used to separate the two elements. For iron sulfide, two elements (sulfur and iron) are heated together so that they form the compound iron sulfide. Although iron sulfide contains both sulfur and iron, it is not a mixture: it is a pure substance. Both the sulfur and the iron have âgiven upâ their individual properties to become a compound.
Confidence votes 36. A pure substance is matter that contains only one type of particle. Compounds consist of two or more elements, but they are still pure substances because there is only one particle-the elements are chemically joined. (For example, water is a compound made of 2 parts hydrogen to 1 part oxygen.).ure substances contain only one type of particles. Even though each molecule in a compound is made of different atoms and each atom is made of protons, neutrons and electrons â¦ , a single moleculs is a single particle and since compounds contain only one type of particle (its molecules), it is a pure substance.
