Consider the following reaction carried out at a constant volume.
4HCl(g) + (g) ⇄ (g) + (g)
ΔH = -114 kJ
Under what conditions will the concentration of at equilibrium increase?

when HCl is addd to the system
when is added to the system
when an inert gas is added to the system
when the temperature of the system is decreased

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.

particle   p is an electron and particle q is a neutron
