CHAPTER 1 Introduction Covering over 70% of the planet’s area‚ the Earth’s oceans could potentially be utilized as a source of virtually inexhaustible renewable energy. Ocean Thermal Energy Conversion (OTEC) is a method that employs naturally occurring temperature differences between warm surface water and colder deep seawater. To be effective a minimum temperature difference between the ocean surface layers is 20C . These temperature gradients exist primarily in specific tropical regions

2014 Hydrogen has number of applications from chemical processing‚ petroleum recovery and refining‚ metal production and fabrication‚ aerospace‚ and fuel cells. The sectors which impose the largest demand for hydrogen are petroleum refinery and ammonia production while automotive fuel is an emerging sector with huge potential in the future. Hydrogen can be generated by the company itself which is utilizing it and can also be purchased from hydrogen producers (other company). The former one called

Introduction The economic benefits of using untreated and treated crop residues as feed for ruminants mainly depends on the source and cost of crop residues‚ cost of treatment‚ cost of urea or other ammonia source‚ on the price of protein supplements‚ as well as on agricultural production and technical levels and other factors. In relation to the potential of crop residue use‚ countries can be divided into four types: Type 1 are developing countries and regions with a high population density

Name____________________ Comparing Rates of Evaporation Several factors determine how fast a sample of liquid will evaporate. The volume of the sample is a key factor. A drop of water takes less time to evaporate than a liter of water. The amount of energy supplied to the sample is another factor. In this lab‚ you will investigate how the type of liquid and temperature affect the rate of evaporation. Problem: How do intermolecular forces affect the evaporation rates of liquids? Pre-Lab:

precipitate forms that does not dissolve as more ammonia solution is added it could mean the cation could be Aluminium‚ Lead (II) or Magnesium. This therefore means that further tests would need to be carried out in order to identify the aluminium. Following the Cation tests we found that sample C was copper as the addition of dilute sodium hydroxide solution formed a pale blue precipitate which didn’t dissolve as more sodium hydroxide was added. Ammonia solution was then added to the compound and the

Iron-Silver Equilibrium In studying equilibrium between iron and silver‚ 0.10 M FeSO4 and 0.10 M AgNO3 were used. The balanced equation for the reaction is: FeSO4 (aq) + 2 AgNO3 (aq) ↔ Fe(NO3)2 (aq) + Ag2SO4 (s) It has a net equation of: Fe2+(aq) + Ag+(aq) ↔ Fe3+(aq) + Ag(s) This part of the experiment

The next step in the process is to inject a safe level of ammonia hydroxide gas into the meat to kill of any food borne pathogens like salmonella and e.coli. By using ammonia hydroxide gas‚ this limits and prohibits the growth of bacteria. The product is then sent to the roller press freeze. Where the product is frozen at -30’F into a thin sheet.

When you carefully added ammonia to your solutions containing copper‚ a light-blue precipitate formed initially that eventually disappeared as more ammonia was added. What do you think this precipitate was? Write an equation. The ammonia molecules attach slowly‚ and in between each attachment‚ there is a chemical equilibrium. The more ammonia is added‚ the more complex is formed‚ as the equilibrium is pushed to the product side. The
