Why was Dalton atomic weight table inaccurate?
-He didn't know the correct ratio of atoms in a chemical reaction and the equipment at the time did not have very accurate numbers.
Which postulate of Dalton's theory is the result of the law of conservation of mass?
This postulate is:" Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process. A chemical reaction simply changes the way atoms are grouped together".
When iron is heated with sulphur iron sulphide is formed .the total mass of iron and sulphur is equal to the mass of iron sulphide why?
According to John Dalton matter can neither be created nor destroyed in a chemical reaction. The law of conservation ofass given by A Lavoisier suggest that total mass of products is equal to the the total mass of reactants .In other words there is no change in mass during a chemical reaction.
Are atoms changed in chemical reactions according to Dalton's Atomic Theory?
According to Dalton's Atomic Theory, atoms are not changed in chemical reactions. Instead, they are rearranged or combined with other atoms to form new compounds. The atoms themselves remain the same, with no change to their identity or fundamental properties.
What breaks food down by chemical reactions?
Enzymes, both outside and inside the cell, are molecules (usually proteins) that enable food to be broken down (although they do not perform this reaction directly).
According to Dalton's atomic theory what can atoms do in a chemical reaction?
separate from atoms they are attahed to, and combine with other atoms
Why did Dalton say that a chemical reaction is a rearrangement of atoms?
because the llamas controlled his mind
explain how dalton atomic theory explains the fact that mass is conserved in chemical reaction?

The fundamental particle of a chemical element according to Daltons theory is?
The atom. Considered by Dalton to be indivisible and indestructible.

What was Dalton's assumption about the composition of water?
Dalton supposed that the chemical formula of water is OH.

Is it possible to convert atoms of one element to atoms of another?
According to Dalton's atomic theory chemical reactions occur when atoms are separated, joined, or rearranged. Atoms of one element, however, are never changed into atoms of another element as a result of a chemical reaction (it is possible only during nuclear reactions and radioactive disintegration).
What is the principle of conservation of matter?
It may also be known as the law conservation of mass; and it states that the total mass of materials present after a chemical reaction is the same as the total mass before the reaction. This law is the basis for Dalton's postulate 3.
