How many moles of H2 would be formed from 2.26 mol of HCI?

Mg + _HCI → _MgCl2 + H2

2.6  moles of HCl will produce moles of H2 =  

Explanation:

Mass of HCl is 36.458 g/mol

Mass of Hydrogen is 1.00794 g/mol

The balanced equation here is

Mg + 2_HCI → _MgCl2 + H2'

2 moles of HCl produces one mole of H2

One mole of HCl will produce moles of H2 =  

2.6  moles of HCl will produce moles of H2 =  

alkaline metals are lithium, sodium, rubidium, potassium, cesium and francium.

alkali metals have electronegativity from 0.7 to 1, lowest in periodic table of elements, which means that alkali metals (i group in periodic table) has positive oxidation number in compounds.

electronegativity is a chemical property that describes the tendency of an atom to attract a shared pair of electrons towards itself.

alkaline metals (far left in main group) have lowest ionizations energy and easy remove valence electrons,

for example, potassium is the alkali metal and has a single valence electron in the outer electron shell.

electron configuration of potassium is: ₁₉k 1s²2s²2p⁶3s²3p⁶4s¹.

they can not exist alone in nature, because they are very reactive.
