Balance the chemical equation by adding coefficients as needed A) HCl(aq)+As2O3(s)+NaNO3(aq)+H2O(I)—— >NO(g)+H3AsO4(aq)+NaCl(aq)
B) TiCl4+H20—>TiO2+HCl
Change these word equations into formula equations and balance them. Be sure to use the proper symbol to indicate the state of each substance as given
C) solution of silver nitrate and aluminum iodide are mixed together, forming solid silver iodide and aqueous aluminum nitrate

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.

answer carbon and three oxygen atoms;
