Answer:
14 ft 7 inches
step-by-step explanation:
since each model inch corresponds to 25 real inches, 7 model inches will correspond to
7×25" = 175"
at 12" per foot, that is 14 feet, 7 inches.
Explanation:
Mendeleev organized it by the atomic mass and mosely did it by atomic number
Explanation:
On one side , there is high concentration of potassium ion and chloride ions. And on other sides high concentration of sodium ions and phosphate ions.
![[K^+][Cl^-]|[Na^+][PO_2^{-}]](https://tex.z-dn.net/?f=%5BK%5E%2B%5D%5BCl%5E-%5D%7C%5BNa%5E%2B%5D%5BPO_2%5E%7B-%7D%5D)
Cell is permeable only to chloride ions.As we can see that chloride ions are only present on the outside of cell .
As we know solute particles move from higher concentration to lower concentration side that is to equalize the concentration of solute particles on both sides. So, chloride ion will move inside the cell until the concentration of chloride ions become equal on both the sides which will result in swelling up of cell.
It's basically when a base and an acid of some kind, come together to make H2O or Water.
Answer: 0.4M
Explanation:
This would be much easier if we first analized what was given from the question. This is illustrated below:
C1 = 2M
V1 = 25mL
C2 =?
V2 = 125mL
C1V1 = C2V2
2x25= C2 x 125
Divide both side by 125, we have:
C2 = (2x25) /125
C2 = 0.4M
Therefore, the molarity of potassium bromide formed will be 0.4M
