When an effective catalyst is added to the reactant mixture, the reaction rate increases. sketch energy profiles both uncatalyzed and catalyzed reactions (e. g. use solid and dash lines). label reactants, products, transition states. the change of enthalpy, and activation energies of both reactions on the diagranm (8 pts.) a one-step exothermic chemical reaction a + b ? c +d occurs very slowly being uncatalyzed. reaction progress

i believe the answer is c. "baking" is the gerund, while "baking blueberry muffins" would be the gerund phrase. hope this ! : )

why is arctic sea ice important? arctic sea ice keeps the polar regions cool and moderate global climate. sea ice has a bright surface; 80 percent of the sunlight that strikes it is reflected back into space. as sea ice melts in the summer, it exposes the dark ocean surface.
