WebMar 15, 2015 · The specimens were designated by MgO I−IV. MgO I−IV were heated in a muffle furnace at 400 °C, 500 °C, 600 °C, or 700 °C for 2 h with an uncertainty of ±3 °C. Preliminary experiments showed that 2 h was sufficient to complete the dehydration of such an amount of Mg (OH) 2. WebThe heat capacity of the solution is given by the specific heat of the solution, C s, multiplied by the mass of the solution: C soln = C s * mass of the solution (8) The specific heat of 0.4 M HCl, which is the average molarity of the acid used during today’s reaction, is 4.07 J g-1 ˚C-1 and its density is 1.01 g/cm3.
