reactions‚ we followed the procedures properly. We started with a small amount of cooper powder in a beaker‚ and added nitric acid to it while the beaker was under a fume hood. We removed the beaker as soon as it was safe to and next we added 25mL of water to the current blue solution. We then added sodium hydroxide to the beaker and then proceeded to place the beaker on to a hotplate and stir the solution with a stirring rod. We then removed the beaker with tongs off of the hotplate and filtered the

Sci/162 Food borne illness short answer questions 1. What is the infectious agent (pathogen) that causes this infectious disease? For example‚ the name of the bacteria‚ virus or parasite. Salmonella is an infection with salmonella bacteria. 2. How is this infectious agent transmitted through food or water? Salmonella can definitely be transmitted through food products‚ mostly raw foods. It can definitely be transmitted on food that has been prepared on surfaces

KREBS CYCLE It refers to a complex series of chemical reactions that produce carbon dioxide and Adenosine triphosphate (ATP)‚ a compound rich in energy. The cycle occurs by essentially linking two carbon coenzyme with carbon compounds; the created compound then goes through a series of changes that produce energy. This cycle occurs in all cells that utilize oxygen as part of their respiration process. It occurs in the matrix of the mitochondria in the presence of CO2.Pyruvic acid diffuses from

Sulfur Cycle Sulfur (S)‚ the tenth most abundant element in the universe‚ is a brittle‚ yellow‚ tasteless‚ and odorless non-metallic element. It comprises many vitamins‚ proteins‚ and hormones that play critical roles in both climate and in the health of various ecosystems. The majority of the Earth’s sulfur is stored underground in rocks and minerals‚ including as sulfate salts buried deep within ocean sediments. The sulfur cycle contains both atmospheric and terrestrial processes. Within the

WATER OUR LIFELINE Water is a transparent fluid which forms the world’s streams‚ lakes‚ oceans and rain‚ and is the major constituent of the fluids of living things. As a chemical compound‚ a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth‚ 96.5% of the planet’s water is found in seas and oceans‚ 1.7% in groundwater‚ 1.7% in glaciers and the ice caps of Antarctica

Does This Thing Work? It operates on a 100 year old proven technology called electrolysis. Whenever you place two pieces of metal in water‚ and apply electricity‚ the water separates into it’s basic molecules‚ Hydrogen and Oxygen (H2O). If you look at the picture on the left‚ you will see H2O molecules connected together in their liquid form which is WATER But when you apply electricity (from your car battery)‚ the molecules separate and form a GAS (called HHO) which is a mixture of Hydrogen

The carbon cycle shows how carbon is recycled -Carbon dioxide is taken in by plants in order to carry out photosynthesis and make food. -The carbon from the carbon dioxide is used to make carbohydrates‚ fats and proteins that make up the plant body. For example the cell wall of plants is made from cellulose - a carbohydrate. -Some of this carbon is returned into the atmosphere as carbon dioxide when the plant respires. When these plants are eaten by other animals this carbon becomes part

I knew that it took about eight hours for the tides to change from high to low‚ sixteen hours for a complete cycle of tides. (9) I didn’t have to wait to learn these things in school. In our house they were everyday knowledge. [1] Often‚ my [10] brother and I‚ joined our mother on her adventures into tidal lands. [2] At the very low tides of the full moon‚ when almost all the water was sucked [11] away‚ we found the [12] hideaways where crabs‚ snails‚ starfish‚ and sea urchins hid in order
