There are many examples of chemical equilibrium all around you. One example is a bottle of fizzy cooldrink. In the bottle there is carbon dioxide (CO2) dissolved in the liquid. There is also CO2 gas in the space between the liquid and the cap
Answer: option C.Water will move into the cell
Explanation:
1) Start by analyzing what the statement means in terms of relative concentrations:
------------------------ | inside the cell ------------ | outside the cell |
sugar --------------- | higher ----------------------- | lower ------------- |
water -------------- | lower ------------------------- | higher ------------ |
2) Osmosis is the process where a barrier (the celll membrane) permits the pass of some component and not others.
The component that can pass is that whose particles are smaller. Sugar molecules (the solute) are bigger than water molecules (the solvent), so sugar molecules cannot pass the cell membrane. Only water can.
3) The driviing force for the motion of water molecules is called diffusion. The diffusion occurs from higher concentrations to lower concentrations.
Hence, the water molecules will from outside the outiside the cell, where they have the greater concentration, toward the inside of the cell, where water hasa the lower concentration.
As result, the water will move into the cell, which is the option C.
A. An Interdependent system of plants, animals, and land
The question asks average kinetic energy. So it is only related with the temperature. The higher temperature is, the higher kinetic energy is. So the answer is (4).
Answer: The bubbles produced are most likely due to oxygen.
Explanation:
Photosynthesis is a phenomenon in which green plants containing chlorophyll use sunlight as a source of energy to convert carbon dioxide and water to form glucose and oxygen.
The balanced chemical reaction for photosynthesis is:

Thus the bubbles produced are most likely due to oxygen.
