Studying the pH of Strong Acid‚ Weak Acid‚ Salt‚ and Buffer Solutions The purpose of the current experiment was to determine the pH of various hydrochloric acid and acetic acid solutions‚ to determine the pH of various salt solutions‚ to prepare a buffer solution‚ and determine the effects of adding a strong acid and strong base to the buffer solution versus adding a strong acid and strong base to water. The measured pHs for the hydrochloric acid solutions were 1.6‚ 2.2‚ 2.9‚ and 3.8. The measured

Stratford-upon-Avon. Analyzing this short story written by Arthur C. Clarke‚ one can conclude that he must enjoy writing about scientific breakthroughs and he utilizes vocabulary that is very different from most authors. The entire story is about a hydrogen bomb destroying the city of Stratford-upon-Avon. The story is told a few days after the incident. The story describes the state of the small town after the bomb was dropped on it. The bomb is destructive‚ there are no humans‚ animals or even dialogues

Energy Systems Assignment By Thysje Fartlek Training Before we started the fartlek training‚ our bodies were using the aerobic system and bi-products of this system are carbon dioxide (CO2) and water (H2O). Our heart rate (HR) was low‚ 60-70 beats a minute‚ and our breathing rate (BR) was slow and deep‚ 1 breathe about every 6 seconds. The demand for fuel was low because we didn’t need to supply the muscles in our body quickly. Once we started walking‚ the demand for fuel increased but only

Synopsis on TITLE: Isolation and Characterization of Potential Phosphate Solubilizing Bacteria from Wheat (Triticum spp) of Bangladesh Introduction Wheat (Triticum spp.) is a cereal grain‚ originally from the Levant region of the Near East and Ethiopian Highlands‚ but now cultivated worldwide. In 2010 world production of wheat was 651 million tons‚ making it the third most-produced cereal after maize (844 million tons) and rice (672 million tons)(FAO‚2010). In Bangladesh‚ wheat cultivation

but because it can cause hazard for the humans and possibly to the environment‚ the hydrogen peroxide is now as an alternative to replace formalin for a common treatment for parasites (Pedersen and Flemming‚ 2010). Graslund et al‚ 1 (2003) showed that the hydrogen peroxide acts as chemical that served several purposes such as to eliminate bacteria‚ parasite and also algae in shrimp farming. However‚ the hydrogen peroxide still can be hazardous for the health of farmers (Boyd‚ 1999) and also affect

Excretory System Review Main Concepts: Describe the major gross anatomical structures of the excretory system. Kidneys: receive about 25% of the cardiac output; produce urine (a fluid containing water‚ ions‚ and small soluble compounds) Ureters: receive urine from the kidneys and conduct it to the urinary bladder. Urine movement involves a combo of gravity and the peristaltic contractions of smooth muscle in the walls of the ureters Urinary Bladder: receives and stores urine prior to elimination
