knowledge of chemistry.
Given the unbalanced equation showing the reactants and product of a reaction
occurring at 298 K and 100. kPa:
P4(s) + Cl2(g) → PC13(C) + energy
1. a. Show a numerical setup for calculating the percent composition by mass of chlorine in
PCl3(l) (gram-formula mass = 137 g/mol).

They cool it down and aluminum cools easily

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.
