What do you think the small piece of filter paper accomplishes when placed on the copper Cu
the density of aluminum is 2.70 g/cm3 and the density of chronium is 7.19 g/cm3. if equal masses of aluminum and chronium are trasnferred in equal volumes of water in separate graduate cylinders, which graduated cylinder would have the greatest vo..
Calculate the amount of heat trasnferred when 3.55 g of Mg(s) reacts at constant pressure. 2Mg(s) + 02(g) ---> 2MgO(s) heat= -1204kJ
what molecule would give the following mass spec data? m/z =15, 29, 43, 57 provide the dominate peaks in the spectrum. the m/z =57 (m-29) is the base peak. and the mz = 43 and 29 ions are also abundent.
Problem- Calculate the vibrational contribution to the heat capacity and the total heat capacity for the following molecules (harmonic vibrational frequencies given)
