iron(II) sulfate to the solution‚ then slowly adding concentrated sulfuric acid (NOT nitric acid‚ for obvious reasons) and watching for a brown ring on the test tube‚ which will indicate the presence of the nitrate ion.[2] Note that the presence of nitrite ions will interfere with this test.[3] The test follows several phases; these have been written as balanced chemical equations: 1: 2 Zn(NO3)2 + 2 H2SO4 ? 2 ZnSO4 + 4 HNO3 4 FeSO4 + 2 H2SO4 ? 2 Fe2(SO4)3 + H2 These two reactions happen

Chapter 1 Introduction Convenience is one of the big trends in the food business. The demand for convenience food products is steadily increasing; therefore‚ understanding convenience food consumption is an important issue. Despite being vital properties of convenience food‚ saving time and effort have not been very successful constructs for predicting convenience food consumption (http://www‚ ncbi.nlm.nih.gov/pubmed/20832437). Convenience food‚ or tertiary processed food‚ is commercially prepared

The purpose of the experiment was to determine which macronutrient‚ nitrogen or phosphorous‚ had a greater influence on cultural eutrophication. It was hypothesized that nitrogen would cause a greater algal growth rate due to its higher abundance required in plant growth. Nitrogen and phosphorous were tested separately‚ where the concentration of each was increased while the other remained constant. The results showed a positive increase in algal growth rate in the phosphorous samples and a negative

levels were very slightly below normal‚ which is no cause for concern. WBCs were present in moderate amounts‚ possibly indicating a urinary tract infection. This could also be due to lack of aseptic technique during collection. The absence of nitrites supports this conjecture (Urinalysis Reagent). The group assignment was to ingest 20 ounces of water within a 15-minute period. Water should be rapidly absorbed into the bloodstream‚ increasing blood volume and lowering osmolarity. This assumption

Amines are aliphatic and aromatic derivatives of ammonia. Amines‚ like ammonia‚ are weak bases (Kb = 10−4 to 10−6). This basicity is due to the unshared electron pair on the nitrogen atom. Classification and nomenclature of amines Amines are classified as primary‚ secondary‚ or tertiary based upon the number of carbon-containing groups that are attached to the nitrogen atom. Those amine compounds that have only one group attached to the nitrogen atom are primary‚ while those with two or three

Doing so can help identify diseases and created treatment and cures for such diseases. As a result‚ various laboratory tests were performed to an unknown microbe (Unknown #1) found in the water of a nearby pond. By identify the microbe‚ the safety of the water will be known to those around it. Materials and Methods
