Answer:
Sorry I am not good at chemistry
Explanation:
Answer:
The negative ion is larger than the original atom. but the same number of positive protons, the size of the ionic radius will increase. When an atom has its electrons attracted to another atom it becomes a positive ion. The positive ion is smaller than the original atom.
Answer:
Use molar mass:)
Explanation:
3.62 mol of Sn (
)=429.694
Since 3.62 has 3 sig figs, limit 429.694 to 3
= 430
The procedure to perform a cell membrane experiment is to:
- Use beetroots cells to measure the permeability of the membrane
- This is done to check the content of the pigment
- It is also meant to check the pigment leaks out of the cells.
<h3>What is a Cell Membrane?</h3>
This refers to the semi-permeable membrane that is around the cytoplasm of a cell.
Hence, we can see that the main purpose of the cell membrane practical experiment is to test the permeability of a membrane and to see the amount of liquid that a membrane can hold.
Please note that your question is incomplete so I gave you a general overview to get a better understanding of the concept.
