Question

a) Suggest one reaction you could use to remove oxygen
from the air without replacing it by another gas. Write the
equation for the reaction you give.
b) How might you remove carbon dioxide from the air?​

Answer 1

Answer:

• a)Chemical reactions are occurring all around you. Plants use sunlight to drive their photosynthetic process and produce energy. Cars and other vehicles burn gasoline in order to power their engines. Batteries use electrochemical reactions to produce energy and power many everyday devices. Many chemical reactions are going on inside you as well, especially during the digestion of food.
• b)Photosynthesis removes carbon dioxide naturally — and trees are especially good at storing carbon removed from the atmosphere by photosynthesis.
