H2co3=co2+h2o
Yes, it is a chemical reaction.
No. It is a chemical change.
Frozen carbon dioxide is still carbon dioxide, so it is a physical change.
chemical change
We inhale oxygen and exhale carbon dioxide as a result of a change in our bodies. Answer - Chemical Change
No. helium is released in outer air but does not lose or change its chemical formula
It is a chemical change.
Yes, combustion of a fuel that produces carbon dioxide is an example of a chemical change. In this process, the chemical composition of the fuel undergoes a change as it reacts with oxygen to form carbon dioxide and release energy.
Chemical
This is a chemical change.
chemical
The reaction of acid on limestone to produce carbon dioxide gas is a chemical change. This is because new substances with different properties (carbon dioxide gas and water) are formed during the reaction, changing the chemical composition of the limestone.
