Shadows are not inverted, the always appear upright.
The answer for the following question is option "C".
Option C is not included in the John Dalton's modern theory of an atom.
- "It states atoms of different elements combine to form new compound" but not new elements
Explanation:
According to John's Dalton's modern theory of an atom:
1. All matter is composed of atoms.
2. Atoms cannot be created,destroyed or subdivided in the ordinary chemical reactions.
3. Atoms of one element differ in the properties from atoms of an another element.
(i.e.)Each and every atom of the element has its own unique properties of their own.
4. Atoms of one element combine with the atoms of another element to <u>form new compound.</u>
5. Atoms that make up an element are identical to each other.
N=1.2·10²⁴
Nₐ=6.0221·10²³ mol⁻¹
n₂(H₂O)=4 mol
n₁(H₂O)=N/Nₐ
n=n₁+n₂=N/Nₐ+n₂
n=1.2·10²⁴/6.0221·10²³ + 4 = 5.99 mol
