The equation represents the decomposition of a generic diatomic element in its standard state. 1 2 X 2 ( g ) ⟶ X ( g ) Assume that the standard molar Gibbs energy of formation of X(g) is 5.41 kJ⋅mol − 1 at 2000. K and − 52.48 kJ⋅mol − 1 at 3000. K. Determine the value of K (the thermodynamic equilibrium constant) at each temperature. K at 2000. K = K at 3000. K =

What is the percentage of hydrogen in nitrogen trihydride

Achemistry student weighs out 0.306 g of citric acid (h3c6h5o7), a triprotic acid, into a 250 ml volumetric flask and dilutes to the mark with distilled water. he plans to titrate the acid with 0.1000 m naoh solution. calculate the volume of naoh solution the student will need to add to reach the final equivalence point. be sure your answer has the correct number of significant digits.

Liquid from a brewery fermentation contains 10% ethanol and 90% water. part of the fermentation product (50,000 kg/h) is pumped to a distillation column on the factory site. under current operating conditions, a distillate of 45% ethanol and 55% water is produced from the top of the column at a rate of one-tenth that of the feed. what is the composition of the waste "bottoms" from the still?
