The air is a mixture of these elements carbon dioxide‚ nitrogen‚ and other stuff. Most mixtures are known to be naturally. The main difference between the compound and the mixture is how they are combined. In the pure substance‚ the only way to know if it is an element or compound‚ is by studying the actually

It consists basically consists of two conductors which are separated by a dielectric medium (non-conductor) such as air‚ waxed paper‚ plastics‚ etc. The capacitance of capacitor is directly proportional to the surface areas and the inverse of the separation of the two conductors. The dielectric constant of the non-conductor is also affecting the capacitance. FIGURE 1 Capacitor symbol For an ideal capacitor‚ the capacitor current iC is proportional to the time rate of change of the voltage across

Purification of solids Aim: To separate a mixture of carboxylic acid and a neutral substance by treatment with aqueous sodium hydroxide and purifying the carboxylic acid‚ measuring the melting points of the neutral and the acid components. METHOD: A mixture of( 5g) Carboxylic acid and neutral compound were separated by adding 2 mol dm-3 sodium hydroxide (25cm3) to the mixture‚ which separated the water soluble sodium from the water insoluble neutral component‚ by filtration. The solid at the filter

CO2 Lab Report Intro Alka-Seltzer tablets are used to treat cold/flu symptoms as it produces CO2 when dissolved in water. The goal of this lab is to calculate the amount of NaHCO3 is needed to produce enough CO2 gas to fill the room. Experimental One Alka-Seltzer tablet was weighed on the analytical balance. Then a piece was measured out to be between 0.21 and 0.28 grams. 500mL of distilled water was added to a 600mL beaker. 80mL of water was mixed with 20mL of 6M HCl in a 150mL beaker. A

Music Appreciation April 30‚ 2013 “The Separation” The separation of church music and secular music during the Baroque period was the beginning of something new. Many people had no idea that the instruments they used during the Renaissance period could do more than they had been doing with them. This brought a new meaning of music and life into the world. It was a great change for music‚ instruments‚ and even people. Church music‚ also known as sacred music‚ was well known in the Renaissance

Abstract: This report presents the reason why the ocean does not freeze in the winter. Since the ocean consists of salt water‚ an experiment was done to test the effect of freezing on salt water compared to pure water. The experiment was conducted three times in order to obtain accurate results and eliminate errors. In addition to the salt and pure water experiment‚ a variation of this experiment was created to test other options. In the variation experiment the effect of freezing on sugar water

The methods used to achieve this objective were also hot vacuum filtration in order to remove suspended solid impurities‚ and isolating the pure acetanilide. In the next lab‚ percent recovered was obtained through weighing the acetanilide sample as well as comparing its melting point range. In this experiment‚ the sample‚ acetanilide was weighted to be 1.523 grams. The sample appeared to be a pale mixture of brown flakes before it was crushed
