A crystal has a specific pattern, has a short range order. The
repeating subunits that are responsible for the shape of a crystal are known as
crystal lattice.
Answer:
41.67 ml HCl
Explanation:
n = M x V
Since the number of moles is the same:
M1 x V1 = M2 x V2
V1 = M2 x V2 /M1 =(0.1 L x 5.0 M) / 12.0 M = 0.041667 L = 41.67 ml
<span>H2S has 2 bonds which means that it has two shared electron pairs. It has 2 lone pairs on electrons. It's the only one where the 2 are the same.</span>
<span>An acetate buffer solution
Volume of Acetic Acid = 50 ml
Concentration of Acetic Acid = 0.20 M
Volume of Sodium Acetate = 50 ml
Concentration of Sodium Acetate = 0.20 M
Volume of NaOH = 5 mL of 0.10 M
The correct pairing is B) Acetic acid with pH > 4.7</span>
Your answer is choice C. That is solid sodium chloride never dissolves to form sodium ions and chloride ions.
Going further to explain, have a look at the question again, we are told that James Proton prepares a saturated solution of sodium chloride in a beaker by adding solid sodium chloride and stirring.
Then when James finishes, crystals of sodium chloride are observed at the bottom of the beaker.
This implies that no more salt was dissolving since the saturation point was reached.
Again suppose he increased the temperature of the reaction, more salts could have dissolved.
