During the light‑dependent reactions of photosynthesis, energy excites electrons in chlorophyll molecules, transforming the energy into chemical energy. What provides the energy that excites the electrons in the chlorophyll molecules?

Look at the potential energy diagram for a chemical reaction. which statement correctly describes the energy changes that occur in the forward reaction?

The pressure, volume, and temperature of a mole of an ideal gas are related by the equation pv = 8.31t, where p is measured in kilopascals, v in liters, and t in kelvins. use differentials to find the approximate change in the pressure if the volume increases from 14 l to 14.6 l and the temperature decreases from 375 k to 370 k. (round the answer to two decimal places.)

What determines the amount of inertia an object has
