Question
- Many dry compounds are found in hydrated What does this mean? The compound has water molecules attached to it, even when it is a dry substance. For example, copper sulfate forms a complex with five water molecules. The symbol is CuSO4×5H2O and is named copper (II) sulfate pentahydrate.
Another hydrated compound containing Sodium, Boron and Oxygen was investigated. 250.00 g of the compound was heated in order to dehydrate it. The remaining material was then decomposed, producing 30.14 g of Na, 28.34 g of B and 73.40 g of O. A mass spectrum revealed that the molecular mass of the compound is 381.42 g/mol. From this information, determine the values of w, x, y and z .

- Ammonium nitrate is a common ingredient found in many fertilizers and is the main component that explodes when fertilizer is made explosive. Ammonium nitrate can be rendered non-explosive (and thus useless to people prone to blowing things up) by mixing it with ammonium hydrogen phosphate. One such mixture of the two compounds was found to be 30.43% nitrogen by mass. What percent of the mixture is ammonium nitrate and what percent is ammonium hydrogen phosphate? By the way, it will be really helpful to have correct formulas for these two compounds.arrow_forwardAssuming gasoline to be pure 2-methylhexane, C7 H16 (actually, it is a mixture of many substances), an automobile getting 26.5 miles per gallon would consume 5.96 x 1023 molecules per mile.
