You are considering two different calcium supplements. One contains 1250 mg of Ca₃(PO₄)₂ and the other is 1500 mg of CaCO₃. As a good chemist you are interested in the percent mass of calcium in each compound, Ca₃(PO₄)₂ versus CaCO₃. Calculate the mass percent of calcium in each compound AND in each supplement serving.

a) Assume that you have two AISI 1045 cylindrical samples with two different diameters: one 1 in. thick and the other 2 in. thick.

a) Assume that you have two AISI 1045 cylindrical samples with two different diameters: one 1 in. thick and the other 2 in. thick. You astenitize and quench both samples in water. Then you cut a section and measure the hardness at the center of each sample. Would you expect to get the same results? Explain your answer. b) Assume that you have two cylindrical steel samples with 1 in. diameter, one made out of AISI 1045 and another...

Two gas cylinders are identical. One contains the monatomic gas neon (Ne), and the other contains an equal mass of the monatomic gas krypton (Kr). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio KEAvg,krypton / KEAvg,neon of the average kinetic energy of a krypton atom to the average kinetic energy of a neon atom. KEAvg,krypton / KEAvg,neon = Need equation with numerical answer!! Thanks

Chemical cold packs contain two separate compartments: one contains water and the other contains NH4NO3 (ammonium nitrate). When the contents of the two compartments combine, the temperature drops to approximately 0°C. A) Is the solvation process exothermic or endothermic? What does that tell us about the sign of DH? B) Is the solvation reaction spontaneous? What does that mean about the sign of DG? C) Since DG = DH - TDS, what do we know about the sign of DS?
