8. In two separate experiments, researchers used laser beams to confine 400 atoms (each) of Na and K in a volume 1.0x10–15 m3 (for a fraction of a second), at a Temperature of 0.00024K (the lowest ever reached for a gas). How many times faster/slower would K atoms be effusing than Na atoms? (1) K atoms effuse 0.77x faster (2) K atoms effuse 0.77x slower

24 points and brainliest to anyone who can answer under 10 minutes with best ! the table below shows the role of different substances during photosynthesis. substance role during photosynthesis glucose stores chemical energy water combines with glucose to form carbon dioxide chlorophyll traps sunlight which of the following statements would correct one of the roles listed in the table? glucose combines with carbon to form water. chlorophyll reacts with light to produce carbon dioxide. water combines with carbon dioxide during photosynthesis. chlorophyll stores chemical energy needed for photosynthesis.
