Answer:
1. <u>No, you cannot calculate the solubility of X in water at 26ºC.</u>
Explanation:
You cannot calculate the solubility of X in <em>water at 26 degrees Celsius </em>because you do not know whether the solution formed by dissolving the crystals in 3.00 liters of water is saturaed or not.
The only way to determine the solubility of the compound X is by dissolving the crystals in certain (measured) amount of water and making sure that some crystals remain undissolved, as a solid on the bottom of the beaker.
Next, you should filter the solution to remove the undissolved crystals. Then, weigh the solution, evaporate, wash, dry, and weigh the crystals.
Then you have the mass of the crystals dissolved and the mass of the solution which will let you calculate the mass of pure water, and then the solubility.
The answer is B: Sound waves cause parts of the ear to vibrate until the waves are converted to electrical signals, which are sent to the brain.
Answer:
NaS2 has two elements within: Sodium & Sulfur.
Basically, the mass percentage of Na2S is:
Sodium = 58.914%
Sulfur = 41.086%
In total, that would equal: 100%.
Explanation:
Well, we know this because Na (Sodium) has 2 atoms & Sodium has no number after it so, that would be an ordinary one atom.
So, knowing that there are more Sodium's than Sulfur, the mass percentage would be higher, than the percentage of Sulfur.
