write a question of chemical reaction CO2 and mg
Answers
Explanation:
Chemical Concepts Demonstrated: Active metal chemistry, the limited usefulness of CO2 fire extinguishers
Demonstration:
A slab of dry ice is cut in half and a small "crater" is melted into one of the pieces.
An ignited magnesium strip is placed in the "crater", and the other half of the dry ice is placed on top.
Observations:
The magnesium strip burns brightly in the air, but continues to burn in the carbon dioxide environment.
Explanations (including important chemical equations):
This reaction is a combustion and oxidation. What's unusual, however, is that magnesium is reactive enough to be combusted and oxidized in a reaction with carbon dioxide:
2 Mg + CO2 -> 2 MgO + C
Under normal combustion/oxidation circumstances, oxygen is the reactant.
Carbon dioxide fire extinguishers work by smothering a fire in carbon dioxide. This is only an effective means of extinguishing a fire if carbon dioxide itself cannot be used as a fuel source.
I hope you can follow me
Answer:
Answer will be
Explanation:
CO2=1 atom of calcium combince with 2atoms of oxygen.
Chemical equation=
C+O2
Mark as brain list ok
And one more thing that is
The reactants should be written on the left hand side and should be written on right hand side.
Example=C+O2 will be your reactants and CO2 will the product this reactants and products I have explained you by that explanation you can do the chemical equation easily.
Your answer will be=C+O2=CO2.
Mark as brain list ok I am showing you one example so that you will understand how to write the chemical equation easily=
product/reactants
C+O2=CO2
It means one atom of calcium combince with the two atoms of oxygen
Mark as brain list.
I have given you your answer and you se this example and by this example you can do any chemical equation easily.
