The variance of a machine learning model measures how much the model’s prediction would fluctuate across different random datasets drawn from the same distribution.

Each of the following sets of quantum numbers is supposed to specify an orbital.  Choose the one set of quantum numbers that is a permissible set (i. e. is correct).

When 1 mol of liquid water, H2O, decomposes to hydrogen gas and oxygen gas at constant temperature and pressure, 285.8  kJ of heat are absorbed.  Write a thermochemical equation for this reaction. [Make sure to write it as the smallest whole number ratio,  use subscripts and superscripts where applicable.  If you need any Greek symbols or arrows,  they are located in the math equation (square root symbol) in the tool bar immediately above this question.]        

When 0.200 moles of solid CaCO3 completely reacts with hydrochloric acid,  3.1 KJ of energy are released.  In addition, three products are formed: aqueous calcium chloride, liquid water and gaseous carbon dioxide.          Write a thermal chemical equation for this reaction.  [Make sure to write it as the smallest whole number ratio,  use subscripts and superscripts where applicable.  If you need any Greek symbols or arrows,  they are located in the math equation (square root symbol) in the tool bar immediately above this question.]    

The products of the combustion (rapid chemical combination of a substance with oxygen, involving the production of heat and light) of ethane, C2H6 , are carbon dioxide and water vapor.  The combustion of one mole of ethane releases 1560 kJ.  Write a thermal chemical equation for this reaction.  [Make sure to write it as the smallest whole number ratio, use subscripts and superscripts where applicable.  If you need any Greek symbols or arrows,  they are located in the math equation (square root symbol) in the tool bar immediately above this question.]
