Regarding intro chemistry, college level, identifying individual elements in a chemical compound / diagram/ drawing of compound i. e. what one line means vs two lines as in case of h2o, for example could we use the compound 3,3-dimethylpantonic acid, what tells me it’s an acid in the diagram of this compound what does the 3 mean and why another 3 and then a dash, what does the dash mean. explain where the di is represented the methyl is represented, the pantonic is represented in the drawing of this compound

Any vitamins or supplements can be obtained without prescription and are widely used as alternative from western medications. most supplements are not valued by the fda or any other drug and food agencies.

Following are the  advantages of the parametric equations: 1) they can be used to graph curves that are not functions, like the unit circle.2) the parameter can be used to represent the quantity that is  useful to  provide us with better information about the graph.3)  it is useful to convert between rectangular equations and parametric equations.with specific reference to chemistry,  parametric equations are employ for solving hydrogen and hydrogen-like ions, quantum mechanically. herein, cartesian coordinates are converted in spherical polar coordinates. the solution obtained, when plotted on spherical polar graph paper, provides visualization of atomic orbital such as s,p,d and f.
