Question: Br2, with molar mass 159.8 g mol–1, effuses half as fast as which of the following rare gases? options: Ar, 39.95 g mol–1 Ne, 20.18 g mol–1 Rn, 222 g mol–1 Kr, 83.80 g mol–1 Xe, 131.3 g mol–1

Molar Mass: Molar mass is defined as the mass contained per unit amount of a substance. A unit of a substance is equal to a mole, where a mole is defined as {eq}6.022\times 10^{23} {/eq} chemical units of a substance. Answer and Explanation: 1

Br 2 has greater molar mass and is therefore easier to vaporize. Br 2 is more electronegative and therefore has greater dipole-dipole forces. Br 2 is less electronegative and therefore its bonding is more ionic. Br 2 is more polarizable and therefore has greater London dispersion forces

Question: Bromine (Br2, molar mass = 159.82 g/mol, density = 3.102 g/mL) reacts with 1,5-cyclooctadiene (CeH12, molar mass 108.18, density = 0.882 g/mL) to form 1,2,5,6-tetrabromocyclooctane (C8H12Bra, molar mass = 427.8). A chemical equation for the reaction is …

Aspirin can be prepared from salicylic acid ( C7H6O3 ), which has a molar mass of 138.12 g/mol, and acetic anhydride ( C4H6O3), which has a molar mass of 102.04 g/mol. The density of acetic anhydride is 1.082 g/mL.

A: According to graham's law, the relationship between the molar mass of gas and time required for… Q: What volume of chlorine gas at 25.2 degrees Celsius and 0.950 atm can be produced by the reaction…

explain why the boiling point of Br2 (59 degrees C) is lower than that of iodine monochloride, ICl (97 degrees C), even thought they have nearly the same molar mass A: Br2 is larger the ICl B: ICl is ionic C: the molar mass dependence of a liquid's boiling point is not an absolute rule, and it should not be applied to all compounds D: it is impossible to say without further informations …
