A reaction happens between barium chloride dihydrate and silver nitrate. How much of each reactant (grams) how much would you need to obtain 2 grams of precipitate, using stoichiometry?

altitude, density, pressure

air gets less dense the higher the altitude and also the air pressure is less as altitude rises.

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!

if you need further assistance, let me know: )
