Burt invested $5,000 ten years ago. He expected to have $13,000 today. He has neither added nor withdrawn any money since his initial investment. All interest was reinvested and compounded annually. As it turns out, he only has $11,500 in his account today. Pick the true statement related to Burt's investment from below. Multiple Choice He earned simple interest rather than compound interest. He earned a lower interest rate than he expected. He did not earn any interest on interest as he expected. He ignored the Rule of 72 which caused his account to decrease in value. The future value interest factor turned out to be higher than he expected.

Ims.sants.co.za/Exam?Question_ID=100948 B-ALI 110 | Academic Literacy B-ALI 110 Examination Semester 12024 Question One consists of five (5) questions. - Read Case Study 2: Suzy gains more confidence, before answering questions 2.1 - 2.5 . - Select NEXT to begin this section. Case Study 2: Suzy gains more confidence As Suzy is daunted by the amount of reading that is required from students (See Case Study 1), she is feeling quite relieved to read the section "Becoming a Skilled Reader", in her CLG (Dison \& Evans, 2020, pp. 17-30). She is particularly interested in Scarborough's Reading Rope model. Now, she is getting ready to answer her first assignment, which is exploring the nature of academic literacy. Her assignment has questions that are based on a short extract from an academic article published in the Journal for Language Teaching. and the title of the article is Student Perception on a Supplementary Multimodal Tool for Academic Literacy (Marais, Nel \& Fourie, 2019): - Extract 1: Unsatisfactory academic performance and low levels of academic literacy, even among students with high academic potential, have become increasingly common in higher education (HE). It is no secret that students experience several challenges when making the transition from secondary school to higher education and that levels of student preparedness differ vastly (Van Dyk, 2010; Van Dyk \& Coetzee-Van Rooy, 2012). - Extract 2: The inadequate preparedness levels of higher education (Van Dyk \& Van de Poel, 2013, p. 44) have led to the implementation of support programmes at various South African universities that target linguistic behaviour through the development of academic literacy and academic language ability of students (Van Dyk \& Van de Poel, 2013; Van Dyk, 2011). - Extract 3: Adequate academic literacy levels are significant predictors of academic success in $ \mathrm{HE}-\mathrm{a} $ theorem supported by, amongst others, Sebolai (2019), Sebolai and Dzansi (2017, p. 250), McKay (2016), Van Rooy and Coetzee-Van Rooy (2015), Van Dyk (2015), Du Plessis and Gerber (2012) and Weideman (2003, p. 58).

Use Hess's law to calculate the amount of heat released when 10 g of ethanol C2H5OH is combusted with oxygen to form carbon dioxide and liquid water. (Molar mass of ethanol = 46 g/mol) Calculate the change in Gibbs free energy in kJ when 10 g of ethanol are combusted, as in question 2.3. A rigid vessel of volume 0.4 m3 containing H2 at 21.25 oC and a pressure of 715x103 Pa is connected to a second rigid vessel of volume 0.75 m3 containing Ar at 30.15 oC at a pressure of 203x103 Pa. A valve separating the two vessels is opened and the mixed gases allowed to cool to a temperature of 12.2 oC. What is the final pressure of the gas mixture in the connected vessel in atm? (1 atm = 101325 Pa)
