Chemistry Homework Assistance

QuestionAI's chemistry problem solver is a middle school chemistry tutoring tool that summarises key chemical reactions and equations in real-time, featuring a robust learning system to empower even those with a weak foundation in chemistry.

You needn't fret over the elemental properties of the periodic table anymore. Here, you can effortlessly access chemical reactions and reaction principles corresponding to each element. Deductive reasoning from microscopic phenomena to discern the original structure of molecules and atoms is a research technique we staunchly champion.

ITEM: ONE Air which is a mixture of different components contains 21% oxygen. Due to a wide spread of respiratory illnesses caused by COVID-19, there was an increas demand for oxygen by patients in the hospitals The government supply of oxygen is not enough and is planning to set up an oxygen production plant with minimal environmental impact. However , the science club members in your school would like to know how the process of production will be carried out TASK: As a Chemistry students, make a write up you will use during the presentation. ITEM: TWO A farmer in a village without electricity always keeps his garden tools ouside th house after the work.After sometimes his tools developed brown coating and was disturbed what happened. TASK: As a chemistry student: a) Point out the environmental factors that led to his tools to develop the brown coating. b) State the properties of one of the environmental factors listed in (a)abo c) What are the uses of the environmental factor in (a)above? d) What in the impact of the browh coating on the tools and how is this solved?
