Answer: The current common definition of an acid and a base is based upon how the substance releases or attracts hydrogen ions (H+). Acids release H+ ions that can turn neutral molecules into positively charged ions, while bases can attract H+ ions from neutral molecules to produce negatively charged ions.

Answer:

An acid is usually a corrosive liquid. The pH value of acids ranges from 1-6 (7 = a neutral). Acids neutralize alkalis, dissolve some metals, and turns litmus (a water soluble mixture used to test materials for acidity) red. Acid donates protons or hydrogen ions and/or accepts electrons. Most acids contain a hydrogen atom bond.

A base donates electrons, accepts protons from acids, or releases hydroxide ions in liquids. The pH value of bases ranges from 8-14. Base is any substance that is slippery to the touch in water, tastes bitter, turns red litmus paper blue, and reacts with acids to form salts, and stimulates certain chemical reactions (base catalysis).

Missing question:
1) the rate of dissolving reaches zero
2) the rate of crystallization reaches zero 
3) the rate of dissolving is zero and the rate of crystallization is greater than zero.
4) both the rate of dissolving and the rate of crystallization are equal and greater than zero.

Answer is: 4) both the rate of dissolving and the rate of crystallization are equal and greater than zero.
Silver chloride (AgCl) dissolves and form silver and chlorine ions, in the same time silver and chlorine ions crystallizate and form solid salt silver chloride.
In equilibrium rates of dissolvinf and crysallization and concentration of ions do not change.

$P_T=112.4torr$

Explanation:

Hello there!

In this case, since these problems about gas mixtures are based off Dalton's law in terms of mole fraction, partial pressure and total pressure, we can write the following for hydrogen, we are given its partial pressure:

$P_{H_2}=x_{H_2}*P_T$
