Question: which compound has the highest melting point? A) KCl B) CH4 C) C6H12O6 D) H2O
The melting point of substances depends on the strength of intermolecular forces. More is the strength of intermolecular forces; more heat must be supplied to loosen the tightly bound atoms in solids (to overcome the intermolecular forces of attraction), more will be the melting point and vice-versa.
Question: 5. The melting point of H2S is lower than H2O. The molar mass of H2S is greater than H2O and we would expect the melting point to be higher for H2S due to greater London dispersion forces.
Question: 1. Physical properties Compound Water, H2O Appearance Colorless, liquid Density 1.0 g/mL Melting Point 0°C 2. Formulas of molecular compounds Formula Formula Name Dinitrogen pentoxide Silicon tetrachloride Phosphorus tribromide N2Os Name Dinitrogen trisulfide Oxygen difluoride Iodine heptafluoride * 3.
The melting point of substances depends on the strength of intermolecular forces. More is the strength of intermolecular forces; more heat must be supplied to loosen the tightly bound atoms in solids (to overcome the intermolecular forces of attraction), more will be the melting point and vice-versa.
Question: The normal melting point of H2O is 273.15 K, and ΔHfus =6010 J⋅mol−1. Calculate the change in the normal freezing point at 258bar, assuming that the density of the liquid and solid phases remains constant at 997 and 917 kg⋅m−3, respectively.
4. (2 points) The melting point of H2O(s) is 0 °C. Would you expect the melting point of H2S(s) to be greater or less than 0 °C? Explain your answer be sure to include information about the IMF's of each compound. 5. (2 points) Identify the intermolecular forces present in the following solids: CH3CH2OH (s) . . CH3CH2CH3 (s) CH3CH2Cl (s) CH3F ...
Consider that the standard measurements for the melting and boiling points of water are taken under specific conditions, like having a pressure of 1 atm. The reported values of H2O for melting and boiling point, are reported values in Standard conditions.
Arrange the following in order of decreasing melting point. Show & explain all work. CaO Ar H2O
The normal melting point of H2O is 273.15 K, and H = 6010 J mol-1. Calculate the change in the normal freezing point at 100. and 500 bar compared to that at 1 bar assuming that the density of the liquid and solid phases remain constant at 997 and 917kg m-3, respectively. Explain why your answer is positive (or negative).
