Answer : The pH of the solution is, 3.37
Explanation : Given,
Concentration of = 0.3 M
Concentration of = 0.8 M
Now we have to calculate the pH of solution.
Using Henderson Hesselbach equation :
Now put all the given values in this expression, we get:
Thus, the pH of the solution is, 3.37
convection is the transfer of heat through the air
Answer:
= 152.40 g
Explanation:
The equation for the reaction is;
Cu(s) + AgNO3 → Ag(s) + Cu(NO3)2
Mass of silver nitrate = 320.0 g × 0.75
= 240.0 g
Molar mass of silver nitrate = 169.87 g/mol
Therefore;
Moles of silver nitrate = 240.0 g/169.87 g/mol
= 1.413 moles
Mole ratio of Silver nitrate to silver metal = 1 : 1
Therefore, moles of silver metal = 1.413 moles
Hence;
Mass of silver metal = 1.413 moles × 107.868 g/mol
<u>= 152.40 g</u>
Number 2 is correct answers
Answer:
Movement of water through a living cell
Explanation:
movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) into a solution of higher solute concentration that tends to equalize the concentrations of solute on the two sides of the membrane.
