    Jarriette kenn D Patenio Jaymar patana Job madronal Do all ideal gases have the same molar volume? An ideal gas has the following equation of state (an equation which relates various thermodynamic properties for a substance‚ such as pressure‚ temperature and molar volume): Pv = RT P - pressure v - molar volume R - universal gas constant T - absolute temperature Clearly the molar volume depends on temperature and pressure‚ so if two gases are at different conditions then they

    In these oxides‚ all the outer electrons in the Period 3 element are being involved in the bonding - from just the one with sodium‚ to all seven of chlorine’s outer electrons. The structures The trend in structure is from the metallic oxides containing giant structures of ions on the left of the period via a giant covalent oxide (silicon dioxide) in the middle to molecular oxides on the right. Melting and boiling points The giant structures (the metal oxides and silicon dioxide) will have high melting

    Chemical Reactions and Equations Chemical Reaction: The transformation of chemical substance into another chemical substance is known as Chemical Reaction. For example: rusting of iron‚ setting of milk into curd‚ digestion of food‚ respiration‚ etc. In chemical reaction new substance is formed which is completely different in properties from the original substance‚ so in a chemical reaction chemical change takes place. Following are the signs of chemical reaction: (a) Change of state of substance

    continue soaking. Six weighing dishes were then labeled “NaCl”‚ “Sr(NO3)2”‚ “CuCl2”‚ “LiCl”‚ ” KCl”‚ and “BaCl2” were obtained. Each contained a scoop full of each metallic solid in the corresponding weighing dish. After this‚ the Bunsen burner was carefully lit. The soaked end of one of the metallic splints was then dipped in one of the metallic salts. The “dipped” wooden splint was then placed into the flame and the color was observed. If any of the solid fell on the lab bench or Bunsen burner the test

    Current‚ Voltage and Power * Electricity is the flow of electric charge. We can describe the flow of electric charge in several ways. These include the quantities Current‚ Voltage and Power. Current * Current (I) is the rate of flow of Charge Carriers‚ such as electrons. Current is usually thought of as moving in the direction of positive charge‚ so from the positive power supply to the negative. However‚ since in metals it is electrons that carry electric charge‚ the actually flow is opposite
