The French chemist Antoine Lavoisier was elected to the French Academy of Sciences for his discovery that roasted metals weighed more than unroasted metals, due to the creation of:
metal carbonates from exposure to carbon dioxide gas
metal hydrides from exposure to hydrogen gas
metal oxides from exposure to oxygen gas
metal nitrates from exposure to nitrogen gas
metal sulfides from exposure to hydrogen sulfide gas
At the atomic level human bodies are worth a fraction of what they are worth at the biomolecular level
Despite that trace elements are needed in small amounts, you can live without them

- Some fish have a bacterium named Edwardsiella tarda growing in them. Edwardsiella tarda can kill fish by infecting their blood, which normally has a neutral pH. Ceviche is a dish that often uses fish as one of the ingredients. To prepare ceviche, the fish, along with other ingredients, is soaked in lemon juice, which has a pH around 2.5. The fish is not cooked using heat. If the fish used in ceviche are contaminated with the organism Edwardsiella tarda, you might be afraid of getting sick from eating ceviche. However, the addition of lemon juice will prevent anyone from getting ill from consuming Edwardsiella tarda.

- Welding is a process that used to attach pieces of metal to one another. In a certain welding process, small pieces of Al (s) and CuO (s) are placed in a crucible and ignited, causing the following highly exothermic reaction to occur. 2 Al + 3 CuO → 3 Cu + Al,0, The copper and aluminum oxide melt. The molten aluminum oxide floats to the top of the crucible. When the steel disk below the crucible melts, the molten copper flows into the weld cavity and welds the pieces of metal together as it cools and solidifies. The setup is represented in the following diagram. Mixture of Al(s) and CuO(s) Crucible Steel Disk Weld Cavity Pieces of Metal to Be Connectedarrow_forwardWhy are food additives used?

The bioconcentration value for TCE and aniline in fish is the same at 1.06mg TCE (or aniline) per kg fish, respectively. Fish is only exposed to these contaminants in its environment. About 54g of fish is consumed in 350days/yr for 30years. Assume bioavailability value of 1. The potency factor for TCE is 1.1 × 10$# kg.day/mg and reference dose is 1.00 × 10$% mg/kg.day. Whereas the potency factor for aniline is 5.7 × 10$* kg.day/mg and reference dose (based on drinking water) is 1.60 × 10$& µg/L. Unlike aniline, TCE is not a carcinogenic compound. There are 70yrs in a lifetime and 365day/yr. a) Using chronic daily intake calculation, determine the non-cancer risk (number of people in one million) for the above case. b) Calculate the cancer risk (number of people in million) for the above case.arrow_forward
