equilirium contant

What percent of CO_2 in air is just sufficient to prevent loss in weight when CaCO_3 is heated at 100^@C ? (Equilibrium contant K for CaCO_3(s) hArr CaO(s)+CO_2(g) is 0.0095 atm at 100^@C )

1kg ice at -10^(@)C is mixed with 1kg water at 100^(@)C . Then final equilirium temperature and mixture content.

Four identical point charges are placed at the corners of a square, A fifth point charge placed at the center of the square experiences zero net force . Is this a stable equilirium for the fifth charge? Explain.

The change in Gibbs free energy of the system alone provides a criterion for the spontaneity of a process at constant temperature and pressure. A change in the free energy of a system at constant temperature and pressure will be : DeltaG_("system")=DeltaH_("system")-T DeltaS_(system") For a system in equilibrium, DeltaG=0 , under conditions of contant....

The natural frequency of an LC - circuit is 1,25,000 cycles per second. Then the capacitor C is replaced by another capacitor with a dielectric medium of dielectric contant k. In this case, the frequency decreases by 25 kHz. The value of k is

If c is r.m.s speed of molecules in a gas and upsilon is the speed of sound waves in the gas, show that c//upsilon is contant and independent of temperature for all diatomic gases.

Let "Delta"_r=|r-1n6(r-1)^2 2n^2 4n-2(r-1)^2 3n^3 3n^2-3n|dot Show that sum_(r=1)^n"Delta"_r is contant.

Water from a tap emerges vertically downwards an intial speed of 1 m/s . The cross-sectional area of the tap is 10^(-4)m^(2) . Assume that the pressure is contant throughout the stream of water and that the flow is steady . The cross-sectional area of the steam. 0.15 m below the tap is
