Children’s toys and jewelry were assessed for their contamination by potentially toxic elements (PTE). This includes traces of As (74.92 g/mol), Cd (112.4 g/mol), Pb (207.2 g/mol), and Zn (65.39 g/mol) among others. The concentrations of these PTEs were determined to characterize the subsequent health risks, and to possibly reinforce better legislation on the manufacturing of these products. If 365 ppb of Zn was observed, what is its equivalent in %(w/w)? A sample of plastic toy was treated resulting to a 500 mL solution.

If the treatment used HNO3 (ρ = 1.51 g/mL) as the solvent during dissolution, and the density of Cd is 8.7 g/mL, what is the concentration of Cd in molality if the amount of Cd found in a 250 mL solution was 24 mg?
Refer to the following equation: Mg (s) + 2HNO3(aq) -> Mg(NO3)2 (aq) + H2 (g) A reaction between 0.359 grams of Mg and 21.12mL of a 0.450M HNO3 solution was conducted in a room witht he following conditions: 27.5 degrees Celius, 723mmHg of atospheric pressure. If .15mL of H2 were collected over water (by the water displacement method), calculate the percent yeild of the reaction. (Pressure H2O at 27.5 degrees Celius = 27.82 mmHg)
One of the chemical controversies of the nineteenth century concerned the element beryllium (Be). Berzelius originally claimed that beryllium was a trivalent element (forming Be3+ ions) and that it gave an oxide with the formula Be2O3. This resulted in a calculated atomic mass of 13.5 for beryllium. In formulating his periodic table, Mendeleev proposed that beryllium was divalent (forming Be2+ ions) and that it gave an oxide with the formula Be2O3. This assumption gives an atomic mass of 9.0. In 1894, A. Combes (Comptes Rendus 1894, p. 1221) reacted beryllium with the anion C5H7O2and measured the density of the gaseous product. Combess data for two different experiments are as follows: I II Mass 0.2022 g 0.2224 g Volume 22.6 cm3 26.0 cm3 Temperature 13C 17C Pressure 765.2 mm Hg 764.6 mm If beryllium is a divalent metal, the molecular formula of the product will be Be(C5H7O2)2; if it is trivalent, the formula will be Be(C5H7O2)3. Show how Combess data help to confirm that beryllium is a divalent metal.

During the discussion of gaseous diffusion for enriching uranium, it was claimed that 235UF6 diffuses 0.4% faster than 238UF6. Show the calculation that supports this value. The molar mass of 235UF6 = 235.043930 + 6 x 18.998403 = 349.034348 g/mol, and the molar mass of 238UF6 = 238.050788 + 6 x 18.998403 = 352.041206 g/mol.

A N2 molecule at 20 ⁰C is released at sea level to travel upward. Assuming that the molecule does not collide with other molecules, how far will it travel before coming to rest? Do the same calculation for a He atom. Hint: to calculate the height h, the molecule will travel, equate its kinetic energy with the potential energy it attains at h, which is mgh. Here m is the mass, and g is the gravitational acceleration
