When carbon dioxide (CO2) and water (H2O) chemically combine, they undergo a process called photosynthesis in plants, where they react in the presence of sunlight to produce glucose (C6H12O6) and oxygen (O2). The overall chemical reaction can be summarized as: 6CO2 + 6H2O → C6H12O6 + 6O2. This process is essential for converting solar energy into chemical energy, sustaining plant life and, indirectly, all life on Earth. Additionally, carbon dioxide can also react with water to form carbonic acid (H2CO3), which plays a role in regulating pH in natural waters.
True
Yeah, mud.
I think it's Carbon Dioxide (CO2) and Water (H2O). Hope that helps!
The new substance formed when elements combine chemically is called a compound. Compounds are made up of two or more different types of elements that are chemically bonded together in a fixed ratio. This bonding results in the formation of a new substance with unique properties different from the elements that make it up.

Yeah, mud.
Hydrogen and Oxygen.

carbon dioxide and water
When carbon dioxide dissolves in water, it forms a compound, not a mixture. The carbon dioxide molecules chemically combine with water molecules to create a new substance with unique properties. This compound is called carbonic acid (H2CO3).
Sucrose can be decomposed chemically as it is a compound composed of carbon, hydrogen, and oxygen atoms. Sodium is an element, and ethanol is a compound made of carbon, hydrogen, and oxygen atoms, but water is a compound that cannot be decomposed chemically as it is already in its simplest form.
No, salt and water do not chemically combine to form a new compound. Salt (sodium chloride) dissolves in water to form a solution, where the salt ions are surrounded by water molecules through a process called hydration.
