WebAP Chem-first quiz. To make Au stronger and harder, it is often alloyed with other metals, such as Cu and Ag. Consider two alloys, one of Au and Cu and one of Au and Ag, each with the same mole fraction of Au. If the Au/Cu alloy is harder than the Au/Ag alloy, then which of the following is the best explanation based on the information in the ... WebApr 7, 2024 · Among the noble gases, Xe has the highest boiling point. The boiling points (in K) of He, Ne, Ar, Kr, Xe and Rn are 4.0, 27.0, 87.0, 121, 165.0 and 211 respectively. On moving down the group, the atomic size increases,greater the size of the atom, greater will be the distortion of electron clouds of the atom and the stronger will be …
Which of the following nonpolar molecules has the highest boiling point …
WebCSe 2. Chemical properties: molecular mass: 169.93 g/mol melting point:-45 °C (lit.) boiling point: 125-126 °C (lit.) stability: decomposes slowly about 1% per month at -30 °C heat of … WebAug 9, 2024 · CS2 has a higher boiling point than CO2 despite having similar intermolecular forces because it has a larger molar mass. Until a certain point, the potential energy of molecules decrease as they get closer to one another. ... Of CO2, CS2 and CSe2, CO2 is the smallest molecule whereas CSe2 is the largest molecule.

Why does cs2 have a higher boiling point than CO2? - Answers
http://www.cse2.com/ WebCarbon diselenide (CSe2) is a liquid at room temperature. The normal boiling point is 125C, and the melting point is -45.5C. Carbon disulfide (CS2) is also a liquid at room … WebThe carbon-to-selenium bond length in CSe2 is greater than the carbon-to-sulfur bond length in CS2. Because the valence electrons in Se are in a higher shell (n=4) than the valence electrons in S (n=3), Se has a larger atomic radius than S has. Therefore, the carbon-to-selenium bond length is greater than the carbon-tosulfur bond length. biotherm with retinol
