You want to analyze a silver nitrate solution. (a) you could add hcl(aq) to the solution to precipitate out agcl(s). what volume of a 0.150 m hcl(aq) solution is needed to precipitate the silver ions from 15.0 ml of a 0.200 m agno3 solution? (b) you could add solid kcl to the solution to precipitate out agcl(s). what mass of kcl is needed to precipitate the silver ions from 15.0 ml of 0.200 m agno3 solution? (c) given that a 0.150 m hcl(aq) solution costs $39.95 for 500 ml and that kcl costs $10/ton, which analysis procedure is more cost-effective?

The diagrams show objects’ gravitational pull toward each other. which statement describes the relationship between diagram x and y? gravity attracts only larger objects toward one another. gravity attracts larger objects only if they are close to one another. if the masses of the objects increase, then the force between them also increases. if distance between the objects increases, then the amount of force also increases.
