Phagocytosis, the amoeba surrounds the food particle and engulfs it. Then it's stored for when the cell needs food.
Answer:
Energy level (n = 4), d subshell (l = 2)
Step-by-step explanation:
The number in 4d tells you the energy level of the subshell: n = 4.
The letter d gives you the secondary quantum number l.
Depending on its value, the letter gives you the shape of the orbital.
l = 0 corresponds to an s orbital (spherical)
l = 1 corresponds to a p orbital (dumb-bell shaped)
l = 2 corresponds to a d orbital (four four-leaf clovers + one that looks like a dumbbell with a doughnut around its middle)
The precipitate of reaction that occurs when silver nitrate solution is mixed with sodium chloride solution is of silver chloride (AgCI).
The chemical equation for this precipitation reaction is as following:
AgNO3(aq) + NaCl(aq) --> AgCl(s) [precipitate]+NaNO3(aq)
- Silver Chloride is a chemical compound which is poorly soluble in water because the chemical bond between Ag+ and Cl is very strong as the two ions are nearly the same size and have similar electronic densities.
- If the chemical bond is strong, it is difficult for water molecules to break this bond to surround the individual ions, thus solubility will decrease.
