In the equation given above, there is conservation of MASS, CHARGE AND ENERGY.
These three parameters are usually conserved during the course of chemical reactions. When any of these parameter experience a reduction during the course of chemical reaction, such loss is always gained by other elements involved in the same reaction, so that at the end of the day, they are not considered as lost.
Answer:
Density independent factor
Explanation:
in dense areas where people livein very close and tight spaces
I think the answer is A. Hope that helped :)
It should remain constant because of the law of conservation of mass and because the flask is sealed no mass will escape
