Hypochlorite ion, used as the chlorinating agent in swimming pools, can decompose exothermically, in rare occasions even causing ires. he principal decomposition mechanism is believed to be
a. Find the steady-state concentration of ClO- 2 ion.
b. Use this to obtain a differential (not integrated) rate law for the concentration of ClO-3 , such that only [ClO- ] and t appear as variables.
An oscillating LC circuit consistingof a 2.0 nF capacitor and a 3.8 mH coil has a maximum volatage of6.0 V. What is the maximum current through the circuit
A capacitor with air between its plates is charged to 130 V and then disconnected from the battery. Whena piece of glass is placed between the plates, the voltage acrossthe capacitor drops to 25 V. What is the dielectric constant of the glass?
