Welding is a process thatused 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 exothermicreaction 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 metaltogether as it cools and solidifies. The setup is represented in the following diagram.Mixture of Al(s)and CuO(s)CrucibleSteel DiskWeld CavityPieces ofMetal to BeConnected Which of the following identifies the metal that is less easily oxidized, Al or Cu, and provides appropriate evidence?Aluminum, because aluminum metal loses electrons and copper ions gain electrons.Aluminum, because aluminum ions gain electrons and copper metal loses electrons.Copper, because copper metal loses electrons and aluminum ions gain electrons.Copper, because copper ions gain electrons and aluminum metal loses electrons.

Introduction According to the given reaction,2 Al+3 CuO→3 Cu+Al2O3 a mixture of Aluminium and CuO…

Which of the following identifies the metal that is less easily oxidized, Al or Cu, and provides appropriate evidence? Aluminum, because aluminum metal loses electrons and copper ions gain electrons. Aluminum, because aluminum ions gain electrons and copper metal loses electrons. Copper, because copper metal loses electrons and aluminum ions gain electrons. Copper, because copper ions gain electrons and aluminum metal loses electrons.

Which of the following identifies the metal that is less easily oxidized, Al or Cu, and provides appropriate evidence? Aluminum, because aluminum metal loses electrons and copper ions gain electrons. Aluminum, because aluminum ions gain electrons and copper metal loses electrons. Copper, because copper metal loses electrons and aluminum ions gain electrons.

A person (70kg) eating locally caught fish from water contaminated with 100ppb TCE and 100ppb aniline. 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$" kg.day/mg and reference dose (based on drinking water) is 1.60 × 10$& ??/L. Unlike aniline, TCE is not a carcinogenic compound. There are 70yrs in a lifetime and 365day/yr. - Using chronic daily intake calculation, determine the non-cancer risk (number of people in one million) for the above case.
