What is the limiting reactant when 5.6 moles of aluminum react with 6.2 moles of water?
alexira [117]

The limiting  reactant  when 5.6  moles   of aluminium react  with  6.2  moles   of water   is

      water( H2O)


      <u><em>Explanation</em></u>

The  balanced    equation is as below

2 Al +3 H2O  →  Al2O3  +3 H2

The mole ratio  of Al :Al2O3  is 2:1  therefore  the  moles  of  Al2O3

  = 5.6 x1/2  =  2.8  moles


The   mole  ratio  of H2O: Al2O3  is 3:1 therefore  the  moles  of Al2O3  produced

                 = 6.2  x1/3= 2.067  moles


since  H2O  yield  less  amount  of Al2O3 ,  H2O   is  the limiting reagent.

myrzilka [38]

The other gas which the article mentioned is Helium gas.

<h3>What is Compression?</h3>

This refers to the squeezing or shortening of a substance which is most often done by  increasing the temperature.

The information scientists hope to gain by compressing this gas into a solid is by studying the molecular structures and using it in the production of other substances which is why Nitrogen and Helium are the gases being studied in this scenario.
