Question

C. Cu + AgNO3 Cu(NO3)2 + Ag D. Pb + Zn(NO3)2 Zn Pb(NO3)2 + 5. Circle anv and all statements that are not present in or reflective of Dalton's atomic theory. Note: I'm asking if these were part of Dalton's theory, not if they are correct scientifically today A. Aspirin (CoHgO4) is always CoHsO4. B. Hydrogen has three naturally-occurring isotopes: protium, deuterium, and tritium. C. Every substance is made up of many small particles called atoms D. Every atom is made up of protons, neutrons, and electrons. E. Atoms are rearranged but identities are not changed during a chemical reaction. F. Conservation of mass. und has the lara centage of P by mass?

Explanation / Answer

Postualtes of Dalton's Atomic Theory are;

1) All matter is made of atoms. Atoms are indivisible and indestructible.

2) All atoms of a given element are identical in mass and properties.

3) Atoms cannot be created or destroyed.

4) Compounds are formed by a combination of two or more different kinds of atoms.

5) A chemical reaction is a rearrangement of atoms.

Hence:

(a)

Aspirin - Molecular formula is C9H8O4. (4th postulate).

(b)

Correct scientifically.

Dalton's theory fails to explain the existence of allotropes;

(c)

Postulate 1

(d)

Correct scientifically.

(e)
