Mothballs in a clothes closet gradually disappear over time, because their components sublime.

Mothballs are small balls of chemical pesticide and deodorant, sometimes used in closets where clothes are susceptible to damage from mold or moths. Mothballs are usually made of naphthalene, 1,4-dichlorobenzene or camphor. What all the compounds have in common is that they sublime at room temperature. Sublimation is a physical change in which matter changes from the solid to the gas state. Once the components are in the gaseous state, the diffuse, and that's why there are no visible remainings over time.

Three beakers contain clear, colorless liquids. One beaker contains pure water, another contains salt water, and another contain

gladu [14]

Pure water may be identified by its density: it will have the lowwest density of the three solutions, given that the solutes (salt and sugar) increase the density (this is the easiests and quickest way).

You can also measure the freezing points or boling points to identify the pure water because the solutes depress the freezing points and increase the boling points.

To differentiate sugar water and salt water, you can probe which one conducts electricity, because salt water is a conductor (given that it ionizes into Na+ and Cl-) but sugar water is not a conductor.

How to do limiting reagents for chemistry?

gavmur [86]

Balance the chemical equation for the chemical reaction.
Convert the given information into moles.
Use stoichiometry for each individual reactant to find the mass of product produced.
The reactant that produces a lesser amount of product is the limiting reagent.
The reactant that produces a larger amount of product is the excess reagent.
To find the amount of remaining excess reactant, subtract the mass of excess reagent consumed from the total mass of excess reagent given.

Answer:An iodide ion is the ion I−. Compounds with iodine in formal oxidation state −1 are called iodides. This page is for the iodide ion and its salts, not organo iodine compounds. In everyday life, iodide is most commonly encountered as a component of iodized salt, which many governments mandate.
