For the reaction CO2(g)+H2(g)=CO(g)+H2O(g) at 1000 K, an equilibrium mixture of the gasses consists of 0.276 mol H2, 0.276 mol CO2, 0.224 mol CO and 0.224 mol H2O. What is the value of delta G for the reaction at this temperature?
Scientists can use mutants to study metabolic pathways. These organisms have a mutation in a gene encoding a metabolic pathway enzyme that results in the inactivation of that enzyme
a solution of NaOH is added to the supnatant liquid until it is strongly alkaline. No precipitate is formed. Which ions are present in each of the precipitates. Which cations are not present in the original solution?
What is the partial pressure of hydrogen in the collection flask? (Note that the hydrogen is collected over water so there will be gaseous water in the flask along with the hydrogen. At 23°C, the pressure of gaseous water is 21.07 torr. The total ..
