Chapter 1 – Chemical Reactions and Equations Science Why should a magnesium ribbon be cleaned before burning in air? Answer Magnesium is very reactive metal. When stored it reacts with oxygen to form a layer magnesium oxide on its surface. This layer of magnesium oxide is quite stable and prevents further reaction of magnesium with oxygen. The magnesium ribbon is cleaned by sand paper to remove this layer so that the underlying metal can be exposed into air. Question 2: Write the balanced

displacement reaction is a type of chemical reaction in which two compounds react in order to create two new chemicals. The two cations and anions switch places with each other which forms two new compounds. As an example AB+CC can switch to AD+CB. Both sides of these equations must balance out in order to be neutral. So any pairs of compounds (such as A+B) must have a total balanced charge. In this example A could have a charge of positive 2 (+2) and B could have a charge of negative 2 (-2) in order

In the first step‚ 2’-OH proton of the ribonuclease sugar undergoes deprotonation by the basic imidazole ring of His12. This produces a 2’-O-‚ which subsequently acts as a nucleophile for attack towards the phosphorus atom of the phosphate group bonded to the 3’-C end of the same ribonuclease sugar. During this process‚ it causes His12 to become protonated‚ thus causing it to become acidic. 21-22 Conversely‚ His119 acts as an acid to facilitate the departure of the leaving 3’-monophosphate group
