Iron(III) chloride (FeCl3) is a compound that is used in the production of computer circuit boards. This solid is produced when chlorine gas (Cl2) is passed over solid metal iron (Fe). Identify the type of chemical reaction that takes place.

Write a balanced chemical equation for the reaction.

Calculate how many moles of iron(III) chloride can be produced from 6. 6 moles of chlorine gas when there is an excess of iron metal.

If there are 3 moles of iron, calculate how many grams of iron(III) chloride will form when there is an excess of chlorine gas

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.
