A chemist measured the amount of lithium hydride produced during an experiment. She finds that 818. grams of lithium hydride is produced. Calculate the number of moles of lithium hydride produced.

B. a graduated substance

The think of process to make something successful

It would be true sodium reacts with water in a violent way 

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.
