James is preparing three solutions of salt water. each of the solutions has the same amount of water in the beaker and a different amounts of salt. in the first beaker, there is one scoop of salt in the beaker. the second beaker has two scoops of salt. the third beaker has three scoops of salt. which of the beakers is the most concentrated solution?

Beaker-3 with three spoon of salts is more concentrated.

Explanation:

$\text{concentration Or molarity}=\frac{\text {mass of the given compound}}{\text{molar mass of that compound}\times \text{Volume of solution in L}}$

$concentration\propto \text{given mass of the compound}$

Higher the given mass of compound in a solution, higher will be the concentration of that solution and vice versa.

Here, the beaker-1 contains one scoop of salt , beaker-2 contains two scoops of salts and beaker-3 contains three scoops of salt with equal amount of water in all the three beakers. So, the increasing order of amount of salt:

1 scoop of salt < 2 scoops of salt < 3 scoops of salt

Since, the amount of salt in in beaker-3 is highest that is with three scoops of salts. The concentration is beaker three will be higher than beaker-2 and beaker-1.

Hence, the order of increasing concentration in all beakers will be:

Beaker-1<Beaker-2<Beaker-3

Answer from: mydoggy152

third beaker

Explanation:

Binary Solution is a homogeneous mixture of two components called as solute and solvent.

Solute is the component which is present in smaller proportion and is solid for solid in liquid solution and solvent is the component which is present in larger proportion and is liquid for solid in liquid solution.

Concentrated solution is one in which there is more amount of solute.

Dilute solution is one in which there is more amount of solvent.

Thus the third beaker which has three scoops of salt has most amount of solute and is the most concentrated solution.

Answer from: Quest

definition

entropy is a measure of the randomness or the extent of disorder of a chemical process.

enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

entropy is measured in joule per kelvin (jk⁻¹) whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.

Fugu, also known as puffer fish, is a sushi delicacy that can also be lethal. puffer fish contain a powerful toxin that can kill an adult a few hours after ingestion. sushi chefs who prepare fugu must be specially trained because any contamination of the toxin-free areas of the fish can be deadly. recently this toxin has been put to good use, as scientists have discovered that a purified form of it can treat severe pain in cancer patients. this recent scientific discovery would fall under which area of chemistry? applied biochemistry pure organic chemistry pure physical chemistry applied inorganic chemistry
