The graph shows the potential energy diagram for an unknown chemical change.
A graph is shown with an inverted graph curve. The curve starts at a higher position on the left side and ends at a lower position on the right side. The higher left position has Reactants written below it and the lower right position has Products written below it. The y axis of the graph has the title Potential Energy with kJ written in parentheses. There is an arrow pointing upwards which is parallel to the y axis. The x axis of the graph has Reaction Pathway along with an arrow pointing towards the right.
Which chemical change could the graph represent? (1 point)
a
Adding heat to decompose calcium carbonate
b
Photosynthesis in plants
c
Electrolysis of water
d
Combustion of iron

Lab reagent, hypothesis test.a reference solution used as a lab reagent is purported to have a concentration of 5 mg/dl. six samples are taken from this solution and the following concentrations are recorded: (5.32, 4.88, 5.10, 4.73, 5.15, 4.75) mg/dl.these six measurements are assumed to be an srs of all possible measurements from solution.they are also assumed to have a standard deviation of 0.2, a normal distributin, and a mean concentration equal to the true concentration of the solution.carry out a significance test to determine whether these six measurements provide reliable evidence that the true concentration of the solution is actually not 5 mg/dl.
