Zinc forms the cation, Zn2+. A mystery anion X is represented as X2. Given this information, what is the molecular formula of the salt it forms with zinc? (Chemical formula use subscript numbers, but for this question any required numbers may be formatted normally. Also, do not insert any spaces between the elements.) Answer: Library Home Students According to the VSEPR electron pairs in the valence energy level repel each other and are therefore arranged as far apart as possible....

please answer ASAP
Kf for chloroform is 4.68 °C/m; normal freezing point of chloroform is -63.5°C. Calculate the freezing point of a solution containing 750 g of chloroform (CHC13) and 85.0 g of a solute that has a molar mass of 154 g/mol. Express your answer to 3 significant figures. Do NOT use scientific notation. Do not include a unit. You must include the negative sign in your answer!
