Least thermally stable
NettetDue to the low melting point of aluminum, 660.5 °C, the thermal stability of its alloys covers the temperature range, which is substantially lower than that of other materials with much higher melting points that, excluding the corrosive factor, can be used to contain molten aluminum alloys, as schematically marked in Figure 1. NettetThe least sterically encumbered precatalyst Co1 reached the peak activity of 1.00 × 10 7 g PE mol −1 (Co) h −1 with MAO at 60 °C and 7.89 × 10 6 g PE mol −1 (Co) h −1 with MMAO at 50 °C, which suggests high thermal stability of the active sites.

Thus, lithium carbonate, Li2C O3 is least thermally stable. Li2C O3 Li2O+C O2↑. 152 Connect with 50,000+ expert tutors in 60 seconds, … NettetCorrect option is C) BeCO 3 has lowest thermal stability. It decomposes to give BeO and CO 2. Hence, it is placed in the atmosphere of CO 2 which prevents decomposition. Be dissolves in alkali to form [Be(OH) 4] 2−. Be 2++4OH −→[Be(OH) 4] 2−. BeF 2 forms complexes with NaF in which Be goes with anion. BeF 2+2NaF→Na 2[BeF 4] 2−.
