Avogadro's principle can be applied when the temperature, volume and pressure are the same. This principle was named after Amedeo Avogadro.

Can propane tanks be stored inside a home basement?

It is not recommended to store propane tanks inside a home basement due to the risk of fire or explosion. Propane tanks should be stored in well-ventilated areas, preferably outdoors. If you must store a propane tank indoors, it should be in a dedicated storage space that meets specific safety regulations.


How many electrons canbe held in the second energy level?

The second energy level (n =2 ) has 1 s orbtial, and 3 p orbitals. The s contains 2 electrons, and each p contains 2 electrons (for a total of 6 electrons in the 3 p orbitals). Thus, the second energy level can hold a maximum of EIGHT (8) electrons.


What kind of material is soap?

The sodium salt of a carboxylic(fatty) acid. In modern terms it is made by boiling sodium hydroxide(lye) and palmitic acid together. The result is sodium palmate (soap). The palmate anion acts as the fats dirt absorber. The sodium cation allows it to dissolve in water. Manufacturers will then put in 'cream's and perfume, to make it 'smooth' and smell nice. Ordinary soap does NOT lather in salt(sea) water, owing to the 'common ion' effect (sodium cation). So a soap that lathers in salt water is made with potassium hydroxide. and palmitic acid. Other organic acids and animal fats canbe used in soap making.


What is conductometric titrations?

Acid-base titrations redox titrations are known to us in which commonly indicators are used to locate the end point eg., methyl orange,phenolphlthalene for acid base titrations and starch solutions for iodemetry type redox process. How ever electrical conductance measurement canbe used as a tool to locate the end point. eg1. HCl vs NaOH Consider a solution of a strong acid, hydrochloric acid, HCl for instance, towhich a solution of a strong base, sodium hydroxide NaOH, is added. The reaction occurs. For each amount of NaOH added equivalent amount of hydrogen ions is removed. Effectively, the faster moving H+ cation is replaced by the slower moving Na+ ion, and the conductivity of the titrated solution as well as the measured conductance of the cell fall. This continues until the equivalence point is reached, at which we have a solution of sodium chloride, NaCl. If more base is added an increase in conductivity or conductance is observed, since more ions are being added and the neutralization reaction no longer removes an appreciable number any of them. Consequently, in the titration of a strong acid with a strong base, the conductance has a minimum at the equivalence point. This minimum can be used instead of an indicator dye to determine the endpoint of the titration. Conductometric titration curve, that is a plot of the measured conductance or conductivity values against the number of milliliters of NaOH solution, is shown in Fig. sorry I could not send the graph, and refer other cases but for a detailed discussion, you may mail --Dr.T.SRINIVASA MURTHY MSC., Ph.D ,Sr Faculty (IIT-JEE) ,NARAYANA ACADEMY HYDERABAD MAIL : vasuchemistry@gmail.com


What is a photometer and how does it work?

Flame photometers work by separating the chemical sample into a constituent atoms and molecules. Then colors are emitted do to the chemicals as they absorb then release energy.
