Why do boron and carbon have high melting points? The melting point of methane is low, so why is that in terms of intermolecular forces? Why does a salt compound give off light (or a colored flame) when burned? Explain what is boiling point and melting point. ...
Which has a higher boiling point: CCl4 or CBr4? Explain. Which has a higher melting point: hexane or 2-methylpentane? Explain. Which of the following solids has the highest melting point? Ar (s) CCl_4 (s) LiCl (s) Among these 8 compounds, which has the highest boiling point?...
CaCl2-NaCl eutectic salt with mole ratio of 1:1 has a low melting point of 504 °C, whereas most-frequently used CaCl2 has a high melting point of 782 °C, thus giving the eutectic salt potential to be employed at a lower working temperature. Table 1 illustrates the theoretical electrode...
To form an ionic compound, there needs to be at least one metal and one non-metal. The metal element is usually the positive charge and the non-metal element is a negative charge. The arrangements of these atoms results in a regular, repeating arrangement called acrystal lattice. A crystal...
The nickel contained in the steels restricts the detrimental effect of chromium. In the SUS-329J1 two-phase stainless steel, the ferritic phase is attacked more than the austenitic phase because the ferrite has a high chromium content and a low nickel content. 展开 ...
The discharge capacity can be initiated at 942 mA h g−1 and maintained at 647 mA h g−1 after more than 100 cycles with a high initial CE of 98.4%. The corresponding capacity fades only ~0.30% per cycle, demonstrating that the GNSCS/S hybrid still has excellent cycle...

● Sodium chloride has a density of 2.16 g/mL, a boiling point of 1465°C, and a melting point of 801°C. ● It doesn’t have any characteristic smell but contains a characteristic taste of its own. ● It is completely soluble in water and other polar solvents, however, it is only...
The molar mass of this compound has been estimated near 58 grams per mole and this compound has a very high melting point.Answer and Explanation: We are required to find the molarity of 5% saline NaCl solution. Hence, we can conclude that the given concentration of the compound is 5 grams...
