URGENT Use the activity series to determine if the following reaction is possible. If it is possible, write the products and balance the equation. If not, explain. (don't worry about making the numbers subscripts, just put all appropriate numbers in their correct location) 2K(s) + ZnCl2(aq) -

True is ur answer : )

Ithink about 50 % of an original isotope's number of atoms remain

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.
