1. A piece of metal with a mass of 147 g is placed in a 50-ml graduated cylinder. The water level rises from 20 mL to 41 mL. What is the density of the metal?

The original substance can be recovered. Is this and physical change or chemical change?

Which of the following requires an oxidizing agent? Al yields Al3+ 2 O yields O2 Cl2 yields 2 Cl- Ag + yields Ag

If a color change occurs when two solutions are mixed has a chemical reaction likely occurred?

Using the following thermochemical data, what is the change in enthalpy for the following reaction? Ca (OH) 2 (aq) + 2HCl (aq) → CaCl2 (aq) + 2H2O (l) CaO (s) + 2HCl (aq) →CaCl2 (aq) + H2O (l), ΔH = - 186kJ CaO (s) + H2O (l) →Ca (OH) 2 (aq), ΔH =
