Dichlorodiphenyl dichloroethylene (C14HaCla. Ma-318 głmol), a chlorinated pesticide, is determined by arlentometric method. A 0.1064 g pesticide sample is broken down in toluene by the action of sodium biphenyl. The released chloride is extracted with water 1He and then titrated with 27.2 ml of 0.037 M AGNO3 using an adsorption indicator. What is the percentage of dichlorodiphenyl dichlorethylene in this example?

The reaction q+r2=r2q is found to be first order in r2 and

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.
