(a) In our Chem 1A lab a student spills 34.22 mL of a 6.021 M sulfuric acid solution on the floor.Dr. Somma neutralized it by pouring 50.71 g of sodium hydrogen carbonate on the spilled acid. Write the balanced chemical equation corresponding to this reaction and classify it. (b) What is the volume, in L, of the carbon dioxide released in the reaction at 25 celsius and 1 atm. (HINT: Find the limiting reagent after the reaction is complete) (c) Did Dr. Somma add too much sodium hydrogen carbonate? If yes, determine how much sodium hydrogen carbonate is left over after the reaction. (d) Did Dr. Somma add too little sodium hydrogen carbonate? If yes, determine how much sulfuric acid needs to be neutralized.
Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
