the concentration of nickel in nigeria coin was delivered with visible spectrophotometer and the following result in percentage was obtained: 3.65,3.59,3.87,4.06,4.11,7.5,3.95,1 .48,3.60,3.76 and 3.99.If the true percentage concentration of nickel in coil was determined by atomic absorption and inductively copied plasma, atomic emission spectrophotometer was 3.92,used the above data to determine the absolute error

It could possibly be beneficial if the experiment is successful.

We can't until we know what we are working with or on

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.
