Answer: Option (d) is the correct answer.

Explanation:

It is known that sea water contains a large amount of common salt, that is, sodium chloride (NaCl). This salt is basic in nature.

Since, it is also known that species which have pH equals to 7 are basic in nature. Species which have pH less than 7 are acidic in nature and species which have pH greater than 7 are basic in nature.

Hence, due to the presence of common salt in sea water its surface is basic in nature.

Therefore, we can conclude that the normal pH of surface sea water is 9.0.

How can the law of conservation of<br> mass for a chemical reaction be expressed?
djverab [1.8K]

Answer:

The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.

Explanation:

How does the concept of conservation of mass apply to chemical reactions? the reactants and products have exactly the same atoms. the reactants and products have exactly the same molecules. the change in the amount of matter is equal to the change in energy.

The first blank can be filled with the Heliocentric model, and the second blank can be filled with Copernicus.  

The heliocentric model known as heliocentrism was proposed by the Renaissance astronomer, mathematician, and the Catholic cleric Nicolaus Copernicus resulting in the Copernican revolution.  

It is the astronomical model, in which the planets and the Earth revolve around the Sun positioned at the middle of the Solar system. Factually, the heliocentric model was in contrast to geocentrism, in which Earth is positioned at the center of the Solar system.
