Answer:
Their amount is not consistent at all parts of the atmosphere
Explanation:
Carbon dioxide and water vapor exists as variable gases in the atmosphere because their amount varies from one part to the other.
- The abundance of variable gases is influenced strongly by activities from the surface.
- This variability occurs a result of the contribution from from life activities on the surface.
- Also, due to properties of the gases, they are not evenly distributed.
- At certain altitudes, the amount of water vapor can be low.
there are 2 copper atoms on the left side of the arrow, but none on the other side. there are also 7 oxygen atoms on the left hand side, but only 5 on the right hand side of the arrow.
Answer:
salt bridge balances the charge when electrons move from one half cell to another half cell.
Explanation:
Explanation: A salt bridge balances the charge when electrons move from one half cell to another half cell. During this process the salt bridge uses its electrolyte solution which further helps in balancing charges in both the half cells. ... Therefore, for each electrochemical cell a new salt bridge is used.
