Use the formula for volume. V = lwh. Plug in the numbers for length,
width, and height. Now we have V = 4.0 x 2.0 x 1.0, which is 8.0. So the
volume of the block is 8.0 cm.

According to Dalton's Law, in a mixture of non-reacting gasses, thetotal pressure<span> exerted is the sum of the </span>partial pressures<span> of the component gasses. In more complicated circumstances, equilibrium states come into effect, but fortunately for us, </span>oxygen<span> is non-reactive with </span>water vapor<span>.</span>
Answer:
Explanation:
The stoichiometry for this reaction is
The rate for this reaction can be written as
![-r_{NO_2}=-\frac{d\left[NO_2\right]}{dt}=\frac{(0.01-0.008)M}{100s}=2\times{10}^{-5}\frac{M}{s}](https://tex.z-dn.net/?f=-r_%7BNO_2%7D%3D-%5Cfrac%7Bd%5Cleft%5BNO_2%5Cright%5D%7D%7Bdt%7D%3D%5Cfrac%7B%280.01-0.008%29M%7D%7B100s%7D%3D2%5Ctimes%7B10%7D%5E%7B-5%7D%5Cfrac%7BM%7D%7Bs%7D)
This rate of disappearence of 
can be realated to the rate of appearence of 
as follows (the coefficients of each compound are defined by the stoichiometry of the reaction)
Gas particles are small and the total volume occupied by gas molecules is negligible relative to the total volume of their container. ... The average kinetic energy of gas particles is proportional to the absolute temperature of the gas, and all gases at the same temperature have the same average kinetic energy
Hope this helps
