The solubility of sodium chloride is about 0.36 g per gram of water at 25 degrees Celsius. g (2 dec places) of NaCl will dissolve in 96 g of water at 25 degrees Celsius. If there were 43.92 g of NaCl dissolved in 122 g of water, the solution would be (unsaturated/saturated/supersaturat ed).

Saturated.

Explanation:

Hello,

In this case, we understand that solubility accounts for the maximum amount of a solute to completely dissolve into a solvent, in such a way, sodium chloride's solubility at 25 °C is 0.36 g of NaCl per gram of water, thus, if a relationship is greater than this value, the solution will be supersaturated, if it is equal saturated and if is less it will be unsaturated. In such a way, for 43.92 g of sodium chloride and 122 g of water, the relationship result:

Thus, such solution would be saturated as the relationship equals the solubility.

Best regards.

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.

it can be observed without changing the identity of the object.

it depends on what substance you're talking about as well as many other factors. in quantum mechanics, the observation of particles affects the observers ability to measure certain properties. for example: you can know the velocity of a particle, but you can't know it's position; or you can know it's position, but not it's velocity. it's like trying to find out where a grain of sand is by throwing other grains of sand at it. once you find out where it is, it's been moved. it's also like trying to find an answer to the question of whether or not a tree falling in a forest makes a sound if nobody is there to hear it. paradoxically, the only way to find out is to be there and hear it.
