Sea salt and rock salt, rock salt is gathered from salt deposits found underground, sea salt is obviously from the sea :/
Hope this helps you
<h3><u>Answer;</u></h3>
C. increasing the surface area of Fe2O3
<h3><u>Explanation;</u></h3>
- The rate of reaction refers to the speed at which products are formed from reactants.
- The rate of any chemical reaction depends on a number of factors which include, surface area, temperature, concentration of reactants among others.
- <em><u>When solids and liquids react, increasing the surface area of the solid will increase the rate of reaction. Thus, decrease in the size of particles causes an increase in the total surface area of the solid and therefore increasing the rate of reaction.</u></em>
Dalton's atomic theory was the first complete attempt to describe all matter in terms of atoms and their properties.
Dalton based his theory on the law of conservation of mass and the law of constant composition.
The first part of his theory states that all matter is made of atoms, which are indivisible.
The second part of the theory says all atoms of a given element are identical in mass and properties.
The third part says compounds are combinations of two or more different types of atoms.
The fourth part of the theory states that a chemical reaction is a rearrangement of atoms.
Parts of the theory had to be modified based on the discovery of subatomic particles and isotopes.
