Answer:
It will not dissolve. More crystals will separate from the solution.
Step-by-step explanation:
If you add a crystal of ammonium nitrate to a supersaturated solution of the solute, it will not dissolve.
Instead, it will act as a "seed" on which more ammonium nitrate crystals will form.
They will separate from the solution as long, colourless, needle-like crystals until the solution is no longer supersaturated.
Answer:
a) 3.98 x 10^-10
Explanation:
Hello,
In this case, for the given pH, we can compute the concentration of hydronium by using the following formula:
Hence, solving for the concentration of hydronium:
Therefore, answer is a) 3.98 x 10^-10
Best regards.
Answer: C) Tetrahedral
Explanation:
The number of electron pairs is 4 that means the hybridization will be but as there are three bonding domains and one nonbonding domain, thus electronic geometry is tetrahedral and the molecular geometry will be trigonal pyramidal.
Linear electron geometry is possible when number of electron pairs is 2 and the hybridization will be .
Trigonal planar geometry is possible when number of electron pairs is 3 and the hybridization will be .
Trigonal bipyramidal geometry is possible when number of electron pairs is 5 and the hybridization will be .
Octahedral geometry is possible when number of electron pairs is 6 and the hybridization will be .
