(a) an optically inactive mixture a (c6h10o4) can be resolved into enantiomers and has the following nmr spectra: 13c nmr: δ 13.5, δ 41.2, δ 177.9 1h nmr: δ 1.13 (6h, d, j = 7 hz); δ 2.65 (2h, quartet, j = 7 hz); δ 9.9 (2h, broad s, disappears after d2o shake) draw either enantiomer; use wedge/dash bonds, including for any h on a chirality center.

Decomposition is the cycle at which bacteria breaks down any organic material into the soil

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.
