exothermic reactions involve release of heat whereas endothermic reaction involve absorption of heat.
Answer:
B.false because if the reactant concentration is disturbed the whole reaction will be affected.
Explanation:
Answer:
A. absorbs light
Explanation:
For an electron to move from a lower energy level to a higher energy level, energy needs to be added to the atom.
In most cases this required energy will be light: The electron of the atom will absorb the energy of the light and move to a higher energy level.
When said electron comes back to the lower energy level, the atom will conversely give off light.
Answer:
Mostly large grains, with a sticky texture, 55% sand, 40% clay, and 5% silt
Explanation: I took the test, hope it helps.
True. For example, electron domain geometry and molecular geometry of water and ammonia are different.
