Important chemistry terms
Firstly, you need to know the three terms of a chemical reaction. Combinations of different substances are called mixtures. Biodegradable Materials that can be broken down by microorganisms Biodiesel Fuel for cars made from plant oils Biofuel Fuel made from animal or plant products Bioleaching Process of extraction of metals from ores using microorganisms Blast Furnace The huge reaction vessels used in industry to extract iron from its ore. How reactive a substance is in relation to another. In fact, a lot of cooking involves chemical changes. Aqueous Solution Definition The mixture made by adding a soluble substance to water Aqueous Solution Abbreviation In Equations aq The smallest part of an element which can be recognised as an element Atomic Number The number of protons which equals the number of electrons in an atom. Gases: These are substances with no fixed shape or definable volume. Aqueous Solution- A solution made by dissolving a substance into water. The fact that this match burns is a chemical property of the match. Examples of elements include iron, carbon, and gold.
Figure 1. Concrete A building material made by mixing cement sand and aggregate crushed rock with water. Thermal Decomposition- The breakdown of compounds via heat.
Chemical engineering terms
Atomic number. Displace When one element takes place of another in a compound. Density- The mass of a substance divided by its volume. Firstly, you need to know the three terms of a chemical reaction. Chemistry, basically, is the study of atoms, elements, compounds, and molecules. Atom- The smallest part of an element. This is the table of the elements, arranged in order of atomic number. The fact that this match burns is a chemical property of the match. These are slightly different. The number of protons plus the number of neutrons.
It is not the same as the endpoint of a titration because the indicator may not change colors precisely when the solution is neutral. Ethene An alkene with the formula C2H4 Exothermic A reaction that gives out energy to the surroundings. Base The oxide, hydroxide or carbonate of a metal that forms a salt as a product when it reacts with acid.
Substances can be pure elements, compounds, or mixtures. This reaction is a chemical property as well Figure 1. The first refers to a chemical solution that does not contain all of the solute that can be dissolved in it.
The definition of the term substance is an example of how chemistry has a specific definition for a word that is used in everyday language with a different, vaguer definition. Aqueous Solution Definition The mixture made by adding a soluble substance to water Aqueous Solution Abbreviation In Equations aq The smallest part of an element which can be recognised as an element Atomic Number The number of protons which equals the number of electrons in an atom.
