If solutions of CaCl2 and K2SO4 are mixed, a solid forms. Which of the following would be the appropriate net ionic equation to represent this process?

Of course: ) what’s your name ?

The answers are 3.c kelvin4.b liquids only

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. 

Ican't see the chart but the density of both nickel and cobalt is 8.90 g/cm3, so it would be one of those.
