Mixture or "pure substance" ? In science it is necessary to know exactly what we are talking about, so before we can even begin to consider matter from a chemical point of view, we need to know something about its composition; is the stuff I am looking at a single substance, or is ...
Why would sodium react more readily with chlorine? Why is oxygen the most abundant element compared to the others? Consider the substance: helium gas. Classify this substance as a pure substance or a mixture. Explain or prove your answer. ...
Is seawater classified as a mixture or a pure substance? Explain. What is the difference between sodium chloride and sodium chlorite? Explain why a magnesium atom is bigger than a sodium atom. Why does the vapor pressure of water decrease when NaCl is added to it?
To prepare the feed with the probiotics, 10 mL of a bacterial suspension with a concentration of 109 cells mL−1 was added to 90 g of feed, and the mixture was homogenized with an electric hand mixer (HM 3100, Braun GmbH, Germany) for 1 min. Subsequently, the feed was allowed to ...
Think of chlorine and sodium chloride. One is incredibly toxic and dangerous, while the other is table salt. Scientific names are means of identifying the structure of a compound, not its uses, benefits or harms. I agree we should eat healthier and less processed foods. I just thinks its ...
Water is a compound that is made from atoms of hydrogen and oxygen combining with each other. Water is one of our most important resources and is necessary for life. Answer and Explanation: Learn more about this topic: Homogeneous Mixture | Properties & Examples ...
Saltwater isa homogeneous mixture, or a solution. Soil is composed of small pieces of a variety of materials, so it is a heterogeneous mixture. Water is a substance; more specifically, because water is composed of hydrogen and oxygen, it is a compound. Oxygen, a substance, is an element....
Since chlorine is a derivative of salt and sodium, sometimes it cannot be easily dissolved. When the chlorination process is done, it goes to a special process where radiation is involved. With the help of Ultraviolet rays, water is then radiated to ensure that the remaining chlor...
The latter needs to be developed in its own right, and students need to be taught to think, not just in “pure” terms (e.g. of whether a substance is “ionic”, “covalent, or “metallic”), but also in applied (e.g. of whether a substance is cheap or expensive). They also ...
A small subset of elements -- helium, neon, argon, krypton, xenon and radon -- are known asnoble or inert gasesand don't readily bond with other elements to form compounds. However, elements such as oxygen, chlorine and fluorine readily combine with other elements to form compounds. ...
