We have a process that reacts 67% ch4 in o2 at 10 atm to form syngas (ahr =-8.5 kcal/mol-ch). (a) estimate the adiabatic reactor temperature at completion if we produce 100% syngas with a feed temperature of 400°c. assume cp =7/2r=7 cal/mol k). (b) estimate the adiabatic reactor temperature if we suddenly begin producing 100% total combustion products (ah, =192 kcal/mol). (c) what must we be concerned with regarding reactor construction materials and pressure relief capabilities to design for this possibility?

An electron moved from shell n = 2 to shell n = 1. what most likely happened during the transition? a fraction of a photon was added. a photon of energy was absorbed. a fraction of a photon was removed. a photon of energy was released.

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?

To calculate the molarity of a solution, you need to know the moles of solute and the
