The basis of learning chemistry is understanding essential terms. If you are studying to pass IGCSE, A-levels, WAEC, or KCSE, or you want to revise your basic knowledge of science, the simplest definitions are the key to your success. This post will examine 20 fundamental chemistry terms and their definitions, presented in an easy-to-understand and accessible format for students. Atom   It is the smallest unit of an element that maintains the chemical characteristics of the component. It has neutrons, protons, and electrons. Element  An element is a pure substance consisting of a single type of atom. Examples are Hydrogen (H), oxygen (O), and gold (Au). Molecule A molecule is a group of two or more atoms that are joined together. Molecules may either be elements (for instance, O 2 ) or compounds (for example, H 2 O). Compound  A compound is a chemical combination of two or more elements in definite proportions. Therefore, to illustrate, water (H 2 O) is a compound consist...

Trainees launching their products in a workshop  One of the crucial reforms of the Technical and Vocational Education and Training (TVET) system in Kenya is modularization, which has had a vital impact on the method of delivering and acquiring vocational skills. Therefore, by breaking down training programs into small, independent units or modules, learners are offered the freedom to work at their own pace. This system also enables learners to begin, interrupt, and continue training without having to redo the entire course, which is quite helpful, especially for part-time students, adult learners, and those already employed. The benefits of modularization include encouraging lifelong learning. Trainees can progressively accumulate their qualifications, taking one module at a time, which helps promote the idea of skills enhancement in learners throughout their lives and careers. Moreover, individual modules will provide specific work-related competencies. This will enable trainees t...

 Instructions:   Read this article,  Alabama pauses executions after a third failed lethal injection attempt , and provide a summary of it.  Summary The article discusses the pause in execution dates for the inmates and requests for the review of the capital punishment state of the state because of various associated challenges. Based on the information from the Alabama Governor's office, Ivy (the governor) requested Steve Marshall (the attorney general) to stop motions for requesting dates for execution for two convicts (The Associated Press, 2022). The statement indicated that the governor implored the Department of Corrections to conduct a comprehensive review of the execution process of the State (The Associated Press, 2022). Furthermore, Ivy appealed to Marshal to halt organizing for any execution dates until the review process is complete. The decision for Ivy to request the review of the state's capital punishment was triggered by the uncompleted execution of ...

  Figure 1:  Mitchell Dufault, the late Yale University Student Physical hazards describe the potential risks contributing to physical injury or user harm. Conditions or factors in laboratories or workplaces cause these potential risks. There are different categories of physical hazards in laboratories. Some of them encompass electrical, hot surface, flammable material, oxidizing material, radiation (ionizing and non-ionizing radiation, UV radiation), glassware hazard, laser hazard, explosive, cryogenic, and high voltage hazards (Odhiambo et al., 2020). Therefore, technician assistants and students need to understand laboratory practices and management to make their space safer. In some circumstances, students think laboratory accidents do not happen to "experienced personnel or brilliant students". This is a misplaced conception, which is justified by an incident that took place at Yale University in 2011. Michele Dufault, a 22-year-old senior student, passed on when h...

  Introduction Relationship between organizational culture and leadership The organization is guided by leadership and organizational culture. Organizational culture describes rules, systems, attitudes, beliefs, and values that influence employees' behaviours in an organization (Chalmers & Brannan, 2023). On the other hand, leadership is the act of leading a group of individuals or an organization (Kruse, 2013). As a result, it is essential to determine the importance of organizational culture to organizational development and how leadership affects organizational culture. Importance of Organizational Culture to Organizational Development Organizational culture is essential to the success of any organization. For instance, it aligns with the objectives of the organization. In such circumstances, it supports the mission and visions of the organization, enabling it to achieve its long-term objectives (Chalmers & Brannan, 2023). This allows workers to work toward common ...

  Data Analysis The data was subjected to univariate and bivariate (correlation) analyses to establish a relationship between the variables for quantitative data. The variables were coded as described in Appendix A, and thematic analysis was used to identify and report themes within qualitative data. As a result, the data was categorized into different themes: psychological issues, psychological methods, school counselling system, benefits of schooling counselling system, seeking help, willingness to talk, talk preference, and psychological improvement. RESULTS Quantitative Data Analysis 56% of participants were females, while 44% were males (Figure 1). Furthermore, Figure 2 indicates that participants in the age brackets 22-25 were the majority, followed by 18-21. Participants over 25 years old were the minority. More participants had pre-master's than pre-undergraduate certificates (Figure 3). The most common psychological issues affecting Chinese students in GIC are anxi...
