When the reactant is a liquid which decomposes to gaseous products. Then the equilibrium is called as______________

When reactants and products are in gaseous state, the equilibrium constant can be expressed in terms of

The normal activity of living carbon-containing matter is found to be about 15 decays per minute for every gram of carbon. This activity arises from the small proportion of radioactive ""_(6)^(14)C present with the stable carbon isotope ""_(6)^(12)C . When the organism is dead, its interaction with the atmosphere (which maintains the above equilibrium activity) ceases and its activity begins to drop. From the known half-life (5730 years) of ""_(6)^(14)C , and the measured activity, the age of the specimen can be approximately estimated. This is the principle of ""_(6)^(14)C dating used in archaeology. Suppose a specimen from Mohenjodaro gives an activity of 9 decays per minute per gram of carbon. Estimate the approximate age of the Indus-Valley civilisation.

A body remain in equilibrium at which depth of liquid ?

A vertical U-tube contains a liquid. The total length of the liquid column inside the tube is 1 . When the liquid is in equilibrium, the liquid surface in one of the arms of the U-tube is pushed down slightly and released. The entire liquid column will undergo a periodic motion.
