Answer:

It is a physical change.

Explanation:

While it is a chemical reaction because the salt gets dissolved, if you were to   boil the water off of a salt solution, all that would be left is salt. This can be done physically. Thus, it is a physical change.

Kaylis [27]

At the most basic level, in order to produce oxygen and a carbohydrate (comprised of carbon, hydrogen, and oxygen), carbon dioxide must react with water as a source of hydrogen.

In order to construct carbohydrate molecules (often glucose) and release oxygen into the atmosphere, photosynthesis utilises carbon dioxide and water. Photosynthesis occurs in organelles called chloroplasts found in eukaryotic autotrophs like plants and algae.

Commonly used notation for photosynthesis is:

6CO_{2} + 6H_{2}O C_{6}H_{12}O_{6} + 6O_{2}

This indicates that the reactants, six carbon dioxide molecules and six water molecules, are transformed into a sugar molecule and six oxygen molecules, the products, by light energy being absorbed by chlorophyll.

Which statement about covalent compounds is FALSE?
Vladimir79 [104]

Answer: b . Covalent compounds can contain a maximum  of 4 different atoms.

Explanation:

The covalent compounds are those compounds that are formed between the non-metals via sharing of electrons. The bonds so formed between these non-metallic atoms are covalent. There can be two or several different kinds of atoms that can form covalent bonds with each other in a single molecule. They use the valence electrons for sharing. The maximum number of valence electrons can be seven.
