contain oxygen. These anions are called oxyanions. When an element forms two oxyanions‚ the one with less oxygen is given a name ending in -ite and the one with more oxgyen is given a name that ends in -ate. NO2- NitriteNO3- NitrateSO32- SulfiteSO42- Sulfate hypo- and per-In the case where there is a series of four oxyanions‚ the hypo- and per- prefixes are used in conjunction with the -ite and -ate suffixes. The hypo- and per- prefixes indicate less oxygen and more oxygen‚ respectively. ClO- Hypoc

(constant) ∙mass of reactant used (mass is less that 3g) When we consider a double displacement reaction; we will need to think about the solubility rules. In our experiment we consider the rule that "Most nitrate (NO3-) salts are soluble." And "Most sulfate are soluble. Notable exceptions are BaSO4......" By this rules we can check the solutions that we will use during the experiment that whether it is soluble or not. Also‚ we can check after the reaction‚ which of the compound is the precipitate.

Based on the reagents used in the synthesis procedure‚ you can assume that the final compound contains copper(II)‚ ammonia‚ sulfate‚ and water. In your analysis‚ you goal is to figure out the mole ratio of each component in the final compound. In other words‚ you will solve for x‚ y‚ z and a in the formula Cux(NH3)y(SO4)z • aH2O.

Introduction: Hydraulic fracturing is the process in which a mixture of chemicals and water are used in combination to stimulate wells and expose minerals that previously would have been much too expensive to access using tradition methods. With the process comes some detrimental environmental consequences‚ like water contamination‚ due to the chemicals used in the liquid mixture. According to an Earthworks article‚ only 0.5 to 2.0% of the “frack fluid” volume content is made up of chemicals‚ which
