"Iron and sulfur are both elements from the periodic table of elements. As such, each one has its own unique set of physical and chemical properties. Iron is a metal, while sulfur is a nonmetal. When these two are heated together, the iron atoms combine with the sulfur atoms to make a compound known as iron sulphide. A compound is different from elements in that it is made from the chemical union of two or more elements. Iron sulphide is not iron or sulfur; it is a pure substance with its own set of distinguishing physical and chemical characteristics. A mixture, on the other hand, is what you get by combining two or more elements, but not chemically combining them. In the case of the iron and the sulfur, if you mix them and provide no heat, you simply have a mixture of iron and sulfur. Mixtures are different from compounds in that they are easily separated. A magnet could be used to separate the iron from the sulfur, because iron is attracted to magnets, while sulfur is not." https://www.enotes.com/homework-help/explain-why-iron-sulphide-compound-not-just-336735 - I hope this helps! :)
They gain energy , it also allows plants to create organic molecules that they use as fuel.
Explanation:
The molar mass of the compounds are incorrect
Answer:
Frost Wedging - Hot and dry
Clay Formation - Cold and Wet
Dissolving - Cold, and dry
Explanation:
The frost wedging happen when the climatic condition is hot and dry. The dry weather compensates the heat and the rock wedging happens quickly. For clay formation the weather has to be cold and wet. The cold weather will make the sand indulge with rock particles resulting in the clay formation.
Answer:
In numerical order left to right, they are arranged by the number of protons in the nucleus of a single atom of each element
