Ethane (C2H6) can rotate around the central C--C bond. When the two -CH3 groups are aligned with each other there is a repulsion between the Hydrogen atoms that results in an energy 2.0 × 10-20 Joules higher than when the Hydrogens are staggered. If the ethane molecules are at room temperature (25° C), what is the ratio of molecules that are perfectly aligned to molecules that are perfectly staggered?

Expert Solution

When the methyl (-CH₃) groups are perfectly aligned in ethane, that conformation is called eclipsed conformation. And when they are as far as possible then they are in staggered conformation.

Rockets can be spin-stabilized; that is, they can fly straighter through space if they rotate around their long axis. Generally, 1 rotation per second is a good angular speed for spin-stabilization. a. Assume the rocket acts like a solid cylinder. The rocket has a mass of 30000 kg (almost all of it fuel) and a radius of 1.00 m. Calculate the angular momentum of the rocket as it spins. Pay attention to units. b. A problem arises because fuels for...

63. Ethylene, C2H4, used to make polyethylene plastics, can be made from ethane, C2H6, one of the components of natural gas. The heat of reaction for the decomposition of ethane gas into ethylene gas and hydrogen gas is 136.94 kJ per mole of C2H4 formed, so it is endothermic. The reaction is run at high temperature, in part because at 800-900 °C, the equilibrium constant for the reaction is much higher, indicating that a higher percentage of products forms at...
