nitrateAmmonium Nitrate How they are manufactured? Ammonium nitrate is made commercially by passing ammonia gas (NH3) and a water solution of nitric acid (HNO3) through a pipe. The ammonia combines with the nitric acid to form ammonium nitrate. The formula for this reaction can be written as NH3 + HNO3 → NH4NO3. Large amounts of heat are released during the reaction‚ so the pipe and supporting equipment must be very strong. The solution of ammonium nitrate in water is allowed to evaporate‚ leaving

the tare weight of a clean crucible. According to WiseGEEK‚ tare weight is the weight of an object (such as a jar‚ a cup‚ or‚ in this case‚ a crucible) when it is empty. You will add 2g of the copper sulfate hydrate crystals into the crucible‚ and then you weigh the crucible with the copper sulfate hydrate crystals and record the data. You then heat the crucible with the hydrate in it with a Bunsen burner for slightly more than 10 minutes‚ and then you weigh and record the data into your data table

Oxidation and Reduction Mnemonic: OILRIG Oxidation Is Loss‚ Reduction Is Gain Oxidation → the loss of electrons from an atom or an ion→ always happens at anode (positive electrode) → think anOde (O2 in the electrolysis of water xp) Redox reactions: Reactions involving the transfer of electrons e.g. burning‚ rusting‚ photosynthesis‚ respiration and the browning of apples. happens in three types of reactions: 1. addition of oxygen 2. removal of hydrogen 3. increase in valency (how easily an atom

Chemistry Internal Assessment: Determining the Enthalpy Change of a Displacement Reaction AIM: To determine the enthalpy change for the reaction between copper(II) sulfate and zinc. BACKGROUND THEORY: Bond breaking is endothermic while bond forming is exothermic. The reaction between copper(ll) sulfate and zinc is exothermic as the energy required to form the bonds of the products is greater than the energy required to break the bonds of the reactants. In an exothermic reaction‚ heat is

Fractional crystallization makes use of the differences of solubility to separate the components of a mixture. Goals: Applying fractional crystallization to separate a mixture of salicylic acid and copper sulfate pentahydrate into its components. Calculate the percent of salicylic acid and copper sulfate pentahy- drate in the mixture. Procedure: Block/McKelvy/with contributions from Georgia Perimeter Faculty (2012) - Laboratory Experiments for Chem 1211L & 1212L Cengage Learning (7th ed.) p. 23&24

RESULT Microbial community analysis Table 1 illustrates the phylogenetic affiliation and the similarity of the bands marked in Fig. 4a which shows the bacterial DGGE fingerprint obtained when ferrous sulfate was used as the energy source (batch-1). Initial sludge had 18 dominant bands out of which 7 bands were not detected on the 2nd day (Fig. 4a) due to changes in the physical condition of the sludge such as aeration and the pH decrease. Dynamics in the microbial community profiling was studied

and interpretation of these findings and finally the conclusion of the study and its findings. Protection of Human Participants This study’s goal is to differentiate the efficacy of clonidine versus phenobarbital in adjunct therapy with morphine sulfate in the treatment of NAS. One of the benefits of this study is the importance of standardization of a weaning protocol. The weaning protocol did not change from day to day and provider to provider as can be the case outside of the study. Another benefit

The sulfate is precipitated as barium sulfate from a solution containing a known mass of fertiliser by adding from a solution containing a known mass of the fertiliser by adding an excess of barium chloride solution: The proportion of sulfate ions and therefore of sulfate in the fertiliser is determined by collecting and weighing the precipitate that is formed during the above reaction
