What is the limiting reactant when 5.6 moles of aluminum react with 6.2 moles of water? unbalanced equation: al + h2o → al2o3 + h2show, or explain, all of your work along with the final answer.

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

      water( H2O)

      Explanation

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.

Given:

Moles of Al = 5.6 moles

Moles of H2O = 6.2 moles

To determine:

The limiting reagent

Explanation:

The chemical reaction is-

2Al + 3H2O → Al2O3 + 3H2

- Based on stoichiometry; 2 moles of Al forms 1 mole of Al2O3

Therefore, 5.6 moles of Al would give: 5.6 Al * 1 Al2O3/2 Al = 2.8 moles Al2O3

-Similarly; 3 moles of H2O forms 1 mole of Al2O2

Therefore, 6.2 moles of H2O would give: 6.2 H2O * 1 Al2O3/3 H2O = 2.07 moles Al2O3

Ans: Since the amount (moles) of Al2O3 formed from H2O is less, water is the limiting reagent.

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
