Hydrogen can be extracted from natural gas according to the following reaction:
CH4(g)+CO2(g) 2CO(g)+2H2(g)
Kp=4.5*102 at 825 K
An 85.0 L reaction container initially contains 22.3 kg of CH4 and 55.4 kg of CO2 at 825 K.

1)Assuming ideal gas behavior, calculate the mass of H2 (in g) present in the reaction mixture at equilibrium.

2)What is the percent yield of the reaction under these conditions?

7. what temperature is need to just dissolve 50 g of nh4cl in 75 g of water? '

Jose and eric were given four samples in lab. the results of their analysis are shown in the table. based on the data they collected, which sample is most likely a metal?

The ozone molecule o3 has a permanent dipole moment of 1.8×10−30 cm. although the molecule is very slightly bent-which is why it has a dipole moment-it can be modeled as a uniform rod of length 2.5×10−10 m with the dipole moment perpendicular to the axis of the rod. suppose an ozone molecule is in a 8000 n/c uniform electric field. in equilibrium, the dipole moment is aligned with the electric field. but if the molecule is rotated by a small angle and released, it will oscillate back and forth in simple harmonic motion.what is the frequency f of oscillation?
