5. For the balanced equation, how many grams of Na SO3 are produced from the reaction of 10.2g of NaOH?
i. Al2(SO3)3 + 6NaOH → 3Na SO2 + 2Al(OH)3
->

What record? the question is incomplete

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. 

The independent is what is changed, the dependent is was is measured or the reaction.
