Based on concentration of solute particles and hence the osmotic pressure the solutions can be classified into three categories , with respect to other solutions
a) isotonic: when concentration of one of the solution is same as of the other solution then they are referred as isotonic to each other.
b) hypertonic: When concentration of the solution is greater than the concentration of other solution then it is said to be hypertonic.
c) hypotonic: when concentration of the solution is lesser than the concentration of other solution then it is said to be hypotonic.
So a solution with high concentration of solute will have higher osomotic pressure and will called to have high pressure or tone hence called as hypertonic.
Thus compartment A will have high concentration and will called as hypertonic while the compartment B will have low concentration and will called as hypotonic
Answer:
Opion 4. The hydrogen in HCl reduce from proton to hydrogen gas (H at ground state)
Explanation:
The reaction is: Mn + HCl → MnCl₂ + H₂
Magnessium changed the oxidation state from 0 to +2
It has increased, so it was oxidized
H changed the oxidation state from +1 to 0
It has decreased, so it was reducted.
Not 100%, but I think it would be 0.0013 because the equation for Molarity is Moles of solute(Mol)/ Liters of solution(L)
Answer is: the height of cylinder is 58.33 ml.
d(rock) = 15 g/cm³.
m(rock) = 50 g.
V(rock) = m(rock) ÷ d(rock).
V(rock) = 50 g ÷ 15 g/cm³.
V(rock) = 3.33 cm³ = 3.33 ml..
h(<span>cylinder) = V(rock) + V(water).
</span>h(cylinder) = 3.33 cm³ + 55 cm³.
h(cylinder) = 58.33 cm³.
