respiration is the process by which humans take in oxygen and give out carbon dioxide. the chemical equation of this process can be represented as follows: c 6 h 12 o 6 + 6o 2 → 6co 2 + 6h 2 o + energy in the reaction given above, it can be noted that c 6 h 12 o 6 is...
Element Names and Symbols Each element may be represented by its atomic number or by its element name or symbol. The element symbol is a one or two letter abbreviation. The first letter of an element symbol is always capitalized. A second letter, if it exists, is written in lower case. ...

Chemistry focuses on the properties and reactivity of the chemical elements. An element is defined as a pure substance, in which the smallest representation is an atom, with every atom of a particular element containing the same number of protons in its nucleus. For example, the element of ...
For example, there are defined conventions for diagrams used in chemistry with coordinate systems that must be adhered to. Other considerations include, for example, pictures in which molecules are represented in the particle model as spheres. Can a water molecule be illustrated in blue or a ...
The words conception, concept, notion, should be limited to the thought of what can not be represented in the imagination; as, the thought suggested by a general term. Perception Vision (ability) Concept An abstract or general idea inferred or derived from specific instances Perception Acuity Per...
learning the 251 times table is more exciting when it is represented in two different ways and is easy to understand. here, you will learn the table of 251 using the repeated addition of 251 and multiplication of 251 by natural numbers. using multiplication using repeated addition 251 × 1 ...
Similarly, the various anoxygenic photosynthesis reactions can be represented as a single generalized formula: CO2 + 2H2A + Light Energy → [CH2O] + 2A + H2O The letter A in the equation is a variable, and H2A represents the potential electron donor. For example, "A" may represent sulfur ...
