    presence of a reinforcement can motivate an individual to repeat the behaviour more frequently. Drive-reduction theory argues that a primary or secondary drive motivates an individual to perform actions that will reduce the drive (Burton‚ et al.). Reduction of the drive is a form of reinforcement leading to the individual repeating the action more frequently (Burton‚ et al.). According to the drive reduction theory‚ sleep is a primary drive which is reduced‚ and thus‚ reinforced by the act of sleeping

    Chemistry Write-Up The Thermal Decomposition of Sodium Hydrogen Carbonate Aim: When Sodium Hydrogen Carbonate (NaHCO3) is heated‚ Carbon dioxide and water are given off to leave a white powder. The aim is to find the equations for this reaction. Hypothesis: The experiment will prove which of the equations below is true. It will tell us whether Sodium Carbonate is produced or Sodium Oxide. 2NaHCO3  Na2CO3 + CO2 + H2O 2NaHCO3  Na2O + 2CO2 + H2O Variables: Independent: Original

    Enclosures: (1) Data Record (2) Data Treatment (3) Environment Impact Research After hours of vigorous examination‚ we have come to the conclusion that calcium chloride (CaCl2) would be the best deicer to use on a naval base over sodium chloride (NaCl) and ethylene glycol (C2H6O2). In order to melt ice‚ deicers lower the freezing point so that the ice melts at lower temperatures. CaCl2 has a freezing point depression of 5°C‚ whereas NaCl has only a 3°C depression‚ and ethylene

Oxidation: the loss of electrons Reduction: the gain of electrons 9.1.2 Deduce the oxidation number of an element in a compound. Always determine elements that never change their oxidation number then ensure the charge of whole molecule is right. N.B. Atoms in elemental state have oxidation numbers of 0 9.1.3 State the names of compounds using oxidation numbers. Example of this in iron‚ can be iron(II) or iron(III) 9.1.4 Deduce

    The purpose of this lab was to measure the reduction potentials of metals and to understand how a reduction-oxidation relationship works to produce spontaneity. Lastly‚ these results were used to determine the Faraday’s constant and Avogadro’s number by electrolysis‚ which is chemical decomposition produced by passing an electrical current through a solution with ions. The primary objective of part one of this experiment was to discover how the properties of an electrochemical cell works. An electrochemical
