Brainliest answer will go to brainliest i need this
classify the following reaction: 2h2o 2h2 + o2
synthesis
neutralization (not this one)
decomposition
single replacement

(the second 2 in 2h20 is small; and the second 2 in 2h2 is small; and the 2 in 02 is also small)

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.
