What happens when you mix an aqueous solution of sodium nitrate with an aqueous solution of barium chloride? (a) there is no reaction; all possible products are soluble. (b) only barium nitrate precipitates. (c) only sodium chloride precipitates. (d) both barium nitrate and sodium chloride precipitate. (e) nothing; barium chloride is not soluble and it stays as a precipitate?

Calculate the change in entropy if br2(l) is converted into gaseous br atoms. s° for br2(l) = 152.2 j/(mol•k) s° for br2(g) = 245.5 j/(mol•k) s° for br(g) = 175.0 j/(mol•k)

Explanation for basic character?

An atom of lithium (li) and an atom of chlorine (cl) engage in a chemical reaction. which correctly describes the structure of the resulting chemical compound? hint: consider the class of each element. the chemical compound will have a network structure. the chemical compound will have triple bonds. the chemical compound will have a ball-and-stick structure. the chemical compound will have double bonds.
