Explanation:
1. When sodium phosphate is added to copper (II) sulfate it gives solid precipitate of copper(II) phosphate and solution of sodium sulfate.
The balanced equation is given as:
![2Na_3PO_4(aq)+3CuSO_4(aq)\rightarrow Cu_3(PO_4)_2(s)+3Na_2SO_4(aq)](https://tex.z-dn.net/?f=2Na_3PO_4%28aq%29%2B3CuSO_4%28aq%29%5Crightarrow%20Cu_3%28PO_4%29_2%28s%29%2B3Na_2SO_4%28aq%29)
2. When sodium phosphate is added to iron(III) chloride it gives solid precipitate of iron (III) phosphate and solution of sodium chloride.
The balanced equation is given as:
![Na_3PO_4(aq)+Fe(Cl)_3(aq)\rightarrow FePO_4(s)+3NaCl(aq)](https://tex.z-dn.net/?f=Na_3PO_4%28aq%29%2BFe%28Cl%29_3%28aq%29%5Crightarrow%20FePO_4%28s%29%2B3NaCl%28aq%29)
Answer:
D. can control the transport of small molecules and ions.
Explanation:
Bilayers are critical components of cell membranes. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. However, an important function of the cell membrane is to allow selective passage of certain substances into and out of cells.
The lipid bilayers are highly permeable to non-polar (fat-soluble) molecules. The permeability of the bilayers to polar (water soluble) molecules is very low, and the permeability is particularly low to large polar molecules. The permeability to charged molecular species (ions) is very low.
When you count atoms, remember to multiply the coefficient number and the subscript number to find the number of atoms of that element. Examples: ▪ 2H2O. Number of atoms Number of molecules = 2. H-4.
Answer don't know at all but i will find out by tomorrow
