At temperature near 800°c, steam passed over hot coke (a form of carbon obtained from coal) reacts to form co and h2: c(s) + h2o(g) ↔ co(g) + h2(g) the mixture of gases that results is an important industrial fuel called water gas.
a) at 800°c the equilibrium constant for this reaction is kp = 14.1. what are the equilibrium partial pressures of h2o, co, and h2 in the equilibrium mixture at this temperature if we start with solid carbon and 0.100 mol of h2o in a 1.00 l vessel?
b) what is the minimum amount of carbon required to achieve equilibrium under these conditions?
c) what is the total pressure in the vessel at equilibrium?
d) at 25°c the value of kp for this reaction is 1.7∙10-21. is the reaction exothermic or endothermic?
e) to produce the maximum amount of co and h2 at equilibrium should the pressure of the system be increased or decreased?

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.

no starving yourself won't it will make you lose more weight what you need to do is find out what foods make you gain weight like bread and meats with fat on
