### Calculating the number of energy states in a particular momentum direction

Given is a 2D scenario of a particle within a container: The circumference shows all the possible 2D spatial directions for a given momentum value of the particle. One of those momentum directions is ...
Previous, I proved that $$\frac{T_2}{T_1}^{C_V/(C_p-C_V)}=\frac{V_1}{V_2}$$ I've been asked to derive a similar expression for a gas that obeys the equation of state $$p=\frac{RT}{(\overline{V}-b)}... 0answers 84 views ### understanding redox reaction I am a total noob in chemistry, so sorry in advance if this is a very stupid question... I am trying to solve this redox reaction:$$\ce{KClO3 + FeSO4 + H2SO4 -> Fe2(SO4)3 + KCl}\ce{K^{+1}Cl^{...
I have to decide whether a $\pu{20 L}$ container with $\pu{0.8 kg}$ ethane can withstand the pressure at $\pu{373.15 K}$. The following information is given: \begin{align} b &= \pu{6.448x10^-2 ...
