Petri Dish pH of Solution
In an investigation to determine the effects of environmental pH on the
germination of dandelion seeds, 25 dandelion seeds were added to each of five
petri dishes. Each dish contained a solution that differed from the others only in
its pH, as shown. All other environmental conditions were the same. The dishes
were covered and observed for 10 days. Using one or more complete sentences,
state the variable in this investigation. Write your answer in ink in the space
provided on your answer paper.
State the dependent variable in this investigation
State a constant in this investigation
State a hypothesis in this investigation.

An enzymatic hydrolysis of fructose-1-p, fructose-1-p(aq) + h2o(l) - fructose (aq) + pi (aq) was allowed to proceed to equilibrium at 25°c. the original concentration of fructose-1-p was 0.2 m, but when the system had reached equilibrium, the concentration of fructose-1-p was only 6.52 x 10^-5 m. calculate the equilibrium constant for this reaction and the free energy of hydrolysis of fructose-1-p.
