give two examples to show how some chemical reactions can be useful
Answers
Answer:
Chemistry happens in the world around you, not just in a lab. Matter interacts to form new products through a process called a chemical reaction or chemical change.
Every time you cook or clean, it's chemistry in action. Your body lives and grows thanks to chemical reactions. There are reactions when you take medications, light a match, and draw a breath.
These examples of chemical reactions from everyday life are a small sampling of the hundreds of thousands of reactions you experience as you go about your day.
Photosynthesis
Photoynthesis
Plants apply a chemical reaction called photosynthesis to convert carbon dioxide and water into food (glucose) and oxygen. It's one of the most common everyday chemical reactions and also one of the most important because this is how plants produce food for themselves and animals and convert carbon dioxide into oxygen. The equation for the reaction is:
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Aerobic Cellular Respiration
Human cells
Aerobic cellular respiration is the opposite process of photosynthesis in that energy molecules are combined with the oxygen we breathe to release the energy needed by our cells plus carbon dioxide and water. Energy used by cells is chemical energy in the form of ATP, or adenosine triphosphate.
Here is the overall equation for aerobic cellular respiration:
C6H12O6 + 6O2 → 6CO2 + 6H2O + energy (36 ATPs)
Answer:
chemical reaction like electrolysis ,electroplating,etc are such which has advanced importance in our daily life .we use cycles which are electroplated .compound like water are decomposed fir obtaining oxygen and hydrogen separately.
