Question

Dissolution of carbon dioxide gas in water is ________ change.
A.chemical
B.physical
C.both  A and B
D.none of the above

Answer 1

Hint: Because of the two twisting modes, the atom is just carefully straight when the measure of bowing is zero. It has been demonstrated both by theory and by Coulomb blast imaging experiments. That this is never, in reality, valid for the two modes without a moment's delay. In a gas stage test of carbon dioxide, none of the atoms are straight because of the vibrational movements.

Complete answer:
Carbon dioxide is a gas that is widely present in nature. As plants are believed to consume it and release oxygen gas animals and humans consume that oxygen gas and release carbon dioxide this is a constant cycle. Also, global warming is a cause of carbon dioxide gas.
When carbon dioxide reacts with water it is both a physical change and a chemical change, first, we will learn what is a physical change and a chemical change. A chemical change is said to have occurred if there is a change in the composition of the compound and a physical change is said to have occurred if there is a change in the physical properties of a compound.
Now, when carbon dioxide reacts with water it forms carbonic acid and this is the chemical change which occurs now when this two compounds combine due to henry’s law which shows the solution of gas into a liquid the pressure also changes which indicate a physical change.
Hence both physical and chemical changes occur when water reacts with carbon dioxide.

Note:  Carbon dioxide is created by all oxygen-consuming living beings when they process natural mixes to deliver energy by breath. It is gotten back to water by means of the gills of fish and to the air through the lungs of air-breathing area creatures, including people. Carbon dioxide is delivered during the cycles of the rot of natural materials and the maturation of sugars in bread, brew, and winemaking.
