2016年2月14日 · The key here is to focus solely on the reaction that produces chloroethane, C2H5Cl, and ignore the one that produces dichloroethane, C2H4Cl, the side product of the reaction. Start by writing the balanced chemical equation for the chlorination of ethane C2H6 (g] +Cl2 (g] → C2H5Cl(g] + HCl(g] Your next step will be to use the 1:1 mole ratio that exists between ethane and chlorine gas to ...

The problem statement: Lets say you have $1 L$ of $2 M$ methane and the same amount of chlorine. Lets also say that both are liquids since those are most likely to react. Now the only way they can

2015年11月8日 · "F"_2 < "Cl"_2 < "Br"_2 As you know, a molecule's boiling point depends on the strength of the intermolecular forces of attraction its molecules exhibit. In your case, you have to find how the boling points of three nonpolar molecules relate to each other. The halogens, which are the lements that make up group 17 of the periodic table, exist as diatomic molecules. Since these molecules are ...

2014年5月17日 · How do I rank the following compounds from lowest to highest boiling point: calcium carbonate, methane, methanol (CH₄O), dimethyl ether (CH₃OCH₃)?

2015年3月7日 · The answer is E) C_4H_10. When judging the strength of intermolecular forces in compounds that only exhibit weak van der Waals interactions, or London dispersion forces (LDF), you have to go by two things Molar mass - the size of the molecule in question - in your case, the longer the carbon chain and the bigger the molar mass, the stronger the LDFs will be; Surface area - the shape of the ...

2014年6月25日 · Based on symmetry alone, we know that H 2S is the only one of these molecules that has a dipole moment. In the case of Cl2, the 2 atoms are identical, so no polarization of the bond is possible, and the dipole moment is zero. In every other case except H 2S, the polarization of charge associated with each bond is exactly cancelled by the other bonds, resulting in no net dipole moment. For CO2 ...

2015年12月14日 · The answer is (b). As you know, the relationship between K_c and K_p is given by the equation color (blue) (K_p = K_c * (RT)^ (Deltan))" ", where R - the universal gas constant T - the temperature at which the reaction takes place Deltan - the difference between the number of moles of gas present on the products' side and the 8*number of moles of gas** present on the reactants' side In order ...

2015年10月13日 · Neon is the fastest. Chlorine is the slowest. We must assume that all these gases are at the same temperature. The rate of diffusion is dependent on the molar mass of the gas. Heavier gas particles move more slowly, lighter ones will move faster. At equal temperatures, all these gases will have the same kinetic energy (KE). Kinetic energy can be calculated using the following relationship: KE ...

Gas stoichiometry is the quantitative relationship between reactants and products in a gas reaction. Using PV=nRT, gas stoichiometry applies when the gases are ideal, and the temperature, pressure, and volume of the gases are all known.

2017年11月11日 · Well, at a guess I would say chlorine gas, i.e. Cl_2.... Why? Because dispersion forces INCREASES as the number of electrons increase in the molecule, and this gives rise to greater possible transient polarities. But a chemist, a scientist, interrogates data, and we should inform our argument with evidence. The "normal boiling point of methane" is -164 ""^@C. "Carbon dioxide sublimes at" -78 ...
