Sodium is a metal from group 1 of the periodic table‚ this is a metal which reacts when it needs to‚ this metal has a low melting and boiling point‚ also it is very dense‚ this shows that when reacting with other substances it will be different and this is because it will not react the same the whole time. The other thing is that this elements electron configuration is 11 which is quite low when comparing them to the other elements in the periodic table. However this metal is more reactive than

Discussion Field observations and lab analysis indicated that‚ there are many types of damages that wall painting can undergo in the Komir temple. All building and decoration materials of Komir temple have been investigated concerning the contamination with soluble salts. Soluble salts represent one of the most important causes of stone decay that may precipitate on the external surface (“efflorescence’s”) or in proximity of the surface (“subefflorescence’s”) [Brai et al 2010]. The degradation induced

All three reactions are exothermic. 1) Dissolving solid sodium hydroxide in water (this heat is actually a “heat of solution” since no true chemical reaction occurs): NaOH (s) ---> Na+ (aq) OH¯ (aq)H1 2) Solid sodium hydroxide is dissolved in a hydrochloric acid solution: H+ (aq) Cl¯ (aq)NaOH (s) ---> Na+ (aq) Cl¯ (aq)O (l)H2 3) A solution of sodium hydroxide is mixed with a hydrochloric acid solution: H+ (aq) Cl¯ (aq)Na+ (aq)

Electrolysis Electrolysis is the process by which ionic substances are broken down into simpler substances using electricity. During electrolysis‚ metals and gases may form at the electrodes. What is electrolysis? Ionic substances contain charged particles called ions. For example‚ lead bromide contains positively charged lead ions and negatively charged bromide ions. Electrolysis is the process by which ionic substances are decomposed (broken down) into simpler substances when an electric

32° F. The temperature may be lower if super cooling occurs or if there are impurities present in the water which could cause freezing point depression to occur. Sodium chloride‚ also known as salt‚ common salt‚ table salt or halite‚ is an ionic compound with the formula NaCl‚ representing equal proportions of sodium and chlorine. Sodium chloride is the salt most responsible for the salinity of the ocean and of the extracellular fluid of many multicellular organisms. As the major ingredient in edible

presentation itself‚ it stated the impacts of road salts and deicers‚ the state uses on the roadways during the winter months. The most commonly used road salt is sodium chloride‚ which is also the most inexpensive and readily available. Recently after more than a half century of its widespread use in North America‚ the use of sodium chloride on the roadways have come under scrutiny by the environmental and scientific communities as well as regulators and legislators. The main residual effects
