ITEM 1
Air pollution has become a major issue for most governments around the world
and Uganda is not exempted from this. According to the World Health
Organization (2016), approximately 85 people in Uganda die every day due to
environmental pollution.
According to the World Air Quality Report (WAQR), Kampala, the capital city
of Uganda is the third most polluted city in the African Continent.
Even though there are government regulatory bodies to control and monitor the pollution
such as National Environmental Management Authority (NEMA), Kampala Capital
City Authority (KCCA) and other organizations, it is the responsibility of every
human residing in the country to keep the country clean and tidy. It is obvious
that every year the number of death is more.
Task;
As a chemistry student, write an article that will be published in this year’s
edition of the school magazine addressing the above challenge.
ITEM 2
A local bridge made of iron has started to rust, causing concerns about its
structural integrity. Your chemistry class is asked to investigate the factors
contributing to the rusting and suggest methods to prevent further damage.
Task;
Write a short notice you can use
ITEM 3
A local oil and gas company requires a reliable supply of nitrogen for enhanced
oil recovery and well maintenance. The company seeks a cost-effective and
efficient method to generate nitrogen.
Task:
As a chemistry learner, design and present a process for generating nitrogen,
ensuring high purity and minimal environmental impact.
ITEM 4
A local food processing company requires a reliable supply of high-purity
nitrogen for packaging their products. The company seeks a cost-effective and
efficient method to produce nitrogen.
Task:
As a chemistry learner, design and present a process for producing nitrogen,
ensuring high purity and minimal environmental impact.
ITEM 5
Mwanga, a curious chemistry student, is preparing for a weekend barbecue and decides to turn it into a learning opportunity. He investigates the combustion process of charcoal, which is primarily carbon (C), in the presence of oxygen from the air. His goal is to better understand the chemical reactions involved, the products formed, and the energy released during the burning of charcoal.
Task:
- Write a balanced chemical equation for the combustion of charcoal in air.
- What are the products of complete combustion of charcoal
