tion A and 50 minutes on Section B. 2 Section A Answer all questions in this section. 0 1Ethyl ethanoate can be made by reacting ethanol with ethanoic acid in the presence of concentrated sulfuric acid. Method 1. A mixture of ethanol, ethanoic acid, and concentrated sulfuric acid, with anti-bumping granules, is heated under reflux for 10 minutes. 2. The apparatus is rearranged for distillation. 3. The mixture is heated to collect the liquid that distils between 70 and 85 °C 4. The ...

rackets. • The maximum mark for this paper is 105. 2 Answer all questions in the spaces provided. 0 1This question is about rates of reaction. Figure 1 shows apparatus used to measure the rate of reaction when an acid reacts with an excess of solid sodium hydrogencarbonate, NaHCO3 When different monoprotic organic acids are used, the rates at which gas escapes can be used to compare the strengths of the acids. A timer is started when the NaHCO3 is added to the acid and the mass of...

HOW CAN CYANIDE ENTER AND LEAVE MY BODY? Cyanide can enter your body if you breathe air, eat food, or drink water that contains it. Cyanide can enter your body through the skin, but this may occur only in people who work in cyaniderelated industries without adequate protective gear. You can be exposed to contaminated water, air, or soil at hazardous waste sites. Once it is in your lungs or stomach, cyanide can quickly enter the bloodstream. Some of the cyanide is changed to thiocyanate...
