PUTTING IT TOGETHER: Classifying Chemical Reactions Purpose: To observe and differentiate between the four different types of chemical reactions. Variables: The independent variables are the sodium chloride‚ sodium carbonate‚ magnesium‚copper‚ copper (11) sulfate‚ silver nitrate‚ oxygen‚ lead(11) nitrate‚ sodium carbonate‚ copper (11) sulfate pentahydrate. The dependent variables are the chemical reactions that are being looked for. For example decomposition‚ synthesis‚ single displacement or double

Source 2 In one version‚ the inner chamber holds the food or drink‚ and the outer chamber houses chemicals that undergo an exothermic reaction when combined. When the user wants to heat the contents of the can‚ a ring on the can is pulled to break the barrier separating the chemicals in the outer chamber. In another type‚ the chemicals are in the inner chamber and the beverage surrounds

is just a brand name for Povidone-iodine. This substance was made in 1955 for a wide variety of medical uses. Here are just a few: Doctors scrub their hands with it before surgery‚ it is used as eye drops and throat rinses‚ it is applied on the skin before general surgery and even used in homes for cuts and scrapes. All of these uses have to do with disinfecting the skin‚ which is what Povidone-iodine does best. Although‚ the amount of concentrated Povidone-iodine changes depending on the use. For

Metals and Halogens reactions Elements such as fluorine‚ chlorine‚ bromine‚ iodine‚ and astatine belong to Group 7‚ Halogens. At room temperature‚ fluorine is a yellow gas‚ chlorine is a pale green gas‚ bromine is a red liquid‚ and iodine is a purple solid. Astatine is a radioactive element‚ therefore it exists only in small amounts. All the halogens exist in diatomic molecules. They have high ionization energies and are the most electronegative elements. Their electron configuration ns2 np5 make

Communist Party of the Philippines (CPP)‚ and the Muslim separatist movement of the Moro National Liberation Front (MNLF). One of his first actions was to arrest opposition politicians in Congress and the Constitutional Convention. Initial public reaction to martial law was mostly favourable except in Muslim areas of the south‚ where a separatist rebellion‚ led by the MNLF‚ broke out in 1973. Despite half-hearted attempts to negotiate a cease-fire‚ the rebellion continued to claim thousands of military
