Is solution physically combined? A solution can be separated by a physical change, such as boiling away the solvent. Substances that are combined chemically can only be separated by a chemical change. Solutions then are combinations of substances that are not chemically combined. Is salt water chemically combined? Saltwater is a homogeneous mixture, or a […]

What is the name of James Chadwick atomic model?
What is the name of James Chadwick atomic model? This atomic model is known as the quantum mechanical model of the atom. In 1932, James Chadwick bombarded beryllium atoms with alpha particles. An unknown radiation was produced. Chadwick interpreted this radiation as being composed of particles with a neutral electrical charge and the approximate mass […]
Why are redox reactions called electron transfer reaction?
Why are redox reactions called electron transfer reaction? Because the oxidation numbers changed, an oxidationâreduction reaction is defined as one in which electrons are transferred between atoms. In the example, each oxygen atom has gained two electrons, and each aluminum has lost three electrons. These reactions are frequently called redox reactions. How can you tell […]

What is the gap between the proteins called?
What is the gap between the proteins called? In biology, a connexon, also known as a connexin hemichannel, is an assembly of six proteins called connexins that form the pore for a gap junction between the cytoplasm of two adjacent cells. This channel allows for bidirectional flow of ions and signaling molecules. Why is a […]
