Ialready posted this question, but im still confused on it.
dinitrogentetraoxide partially decomposes according to the following equilibrium:
n2o4 (g) -> 2no2 (g) < - a 1.00-l flask is charged with 0.400 mol of n2o4. at equilibrium at 373 k, 0.0055 mol ofn2o4
remains. keq for this reaction is ? . so my steps: n2o4 (g) -> 2no2 (g) initial conc. 0.400 mol 0 mole (no reaction yet) change -0.3945 mol + 2 x 0.3945 mole (based on equation above)
equilibrium 0.400-0.3945 mol 0.7890 mole 0.0055 mol 0.7890 keq = [no2]2/[n2o4] keq = (0.789)^2/(0.0055) =113 but my book says the answer is 0.87?

56.16 gregor mendel was the first scientist to use statistics to analyze scientific data. before mendel's experiments, scientists believed that organisms acquired traits from their environment and passed them on to their offspring. after mendel's discoveries were accepted, scientists realized that traits passed to offspring were the result of genes being passed from parents to offspring. this is an example of pls

The human eye contains a molecule called 11-cis-retinal that changes shape when struck with light of sufficient energy. the change in shape triggers a series of events that results in an electrical signal being sent to the brain that results in vision. the minimum energy required to change the conformation of 11-cis-retinal within the eye is about 164 kj/mol.
