1. Гексозы имеют одинаковую формулу С6Н12О6. С точки зрения строения молекулы эти вещества отличаются друг от друга:
1) числом гидроксильных групп
2) взаимным расположением заместителей при ассиметрических атомах углерода
3) строением углеродного скелета
4) расположением альдегидной группы в углеродной цепи

Noble gases is far right

Maybe you should get some from your teacher and learn more so you can get your grades up and maybe study a bit more

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. 

Change of state has wrong energy change - option 2

brian made this table to organize his notes on changes of state. depostion is a change of state that has the wrong energy change listed. it is utilized to collect data as a portion of the development means and in restricted conditions which may be applied at test.

a deposition in the authority of the united states or research for development in the authority of canada includes the catching of affirmed. the out-of-court verbal assertion of a spectator that may be lessened to a printed record for succeeding application for discovery purposes.
