"Conservation of Mass in Chemical Reactions" Quantitative Study of Chemical Reactions PPT Teaching Courseware
Description
"Conservation of Mass in Chemical Reactions" Quantitative Study of Chemical Reactions PPT teaching courseware, 23 pages in total.
qualitative research
What are these changes?
How does the quality of saplings change?
Thinking of the tree and its surrounding environment as a whole, does the total mass of matter change?
Ask a question
Does the total mass of a substance change before and after a chemical reaction?
Conjectures and Assumptions
The total mass of the substance before and after the chemical reaction remains unchanged.
concept construction
Conservation of mass
The sum of the masses of each substance participating in a chemical reaction is equal to the sum of the masses of each substance produced after the reaction. This law is called the law of conservation of mass.
All chemical reactions follow the law of conservation of mass!
Expand and improve
From both macro and micro perspectives, what new insights do you have about these two changes?
Carbon dioxide (CO2) + water (H2O) → organic matter (C.H.O) + oxygen (O2)
Organic matter (C.H.O) + oxygen (O2) → carbon dioxide (CO2) + water (H2O)
How to treat:
"You may contain an atom in your body that was found in dinosaurs tens of millions of years ago"?
Home experiment
Use household items to design and complete small home experiments to verify the law of conservation of mass.
Design and install the experimental device yourself, fill in the experimental report, and submit it together with the experimental device.
Information reference:
The reaction between vinegar and alkaline noodles:
Sodium carbonate + acetic acid → sodium acetate + water + carbon dioxide
The reaction between toilet cleaning liquid and iron nails:
Iron + dilute sulfuric acid → ferrous sulfate + hydrogen
