true
Explanation:
in a solution solvent is the one in which solute is been dissolved that is solvent is in greater amount.
Answer : The concentration of ion is, 0.00371 M
Explanation :
First we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Now we have to calculate the concentration of ion.
The solubility equilibrium reaction of will be:
The expression for solubility constant for this reaction will be,
Thus, the concentration of ion is, 0.00371 M
Answer:oxygen is the central atom in water,it has two lone pairs of electrons, the bond angle is 104.27° The ideal H-O-H bond angle ought to have been 109.28°
Explanation:
The presence of lone pairs causes slight distortion in the bond angles of molecules. This distortion increases with the number of lone pairs present. Water has two lone pairs hence a greater distortion compared to ammonia.
