If 22.15 mL of 0.100 M sulfuric acid is required to neutralize 10.0mL of lithium hydroxide solution, what is the molar concentration of the base?H2SO4(aq) + 2LiOH(aq) -right arrow Li2SO4(aq) + 2 H2O(I)
Firefly luciferase is the enzyme that allows fireflies to illuminate their abdomens. Because this light generation is an ATP-requiring reaction, firefly luciferase can be used to test for the presence of ATP.
