Wastewater from a cement factory contains a 0.25g of Ca2+ ion and 0.056g of Mg2+ ion per 100.0 L of solution. The solution density if 1.001g/mL. Calculate the Ca2+ and Mg2+, molarity, molality, mol fraction, and the PPM. Please show examples.
Develop an argument based on bond enthalpies for the importance of SiO bonds in substances common in the Earth's crust in preference to SiSi or SiH bonds
To the alchemists, gold was the material representation of purity. It is a very soft metal that can be hammered into extremely thin sheets. If a 1.07 g piece of gold is hammered into a sheet whose area is 30.0 ft2,
