Dalton viewed chemical change as what process?
Dalton viewed chemical change as the process of atom rearrangement. Using the atomic theory he came up with, he believed that chemical reactions rearranged the atoms into different combinations.
True or False: A chemical reaction is the rearrangement of atoms you start with to form new compounds?
True
When a chemical reaction occurs atoms are never?
When a chemical reaction occurs atoms get ionized. Atoms are never created nor destroyed in a chemical reaction.
Chemical reactions involve the rearrangement of atoms not the production or destruction of what?
atoms bcoz atom can neither b created nor destroyed.
How does Dalton atomic theory explain the law of conservation of mass?
Dalton doesn't explain the law of conservation of mass.

True or False: A chemical reaction is the rearrangement of atoms you start with to form new compounds?
True
What is Dalton's atomic theory?
1. All matter is made of atoms. 2. All atoms of a given element are identical in mass and properties. 3. Atoms are indivisible and indestructible. 4. A chemical reaction is a rearrangement of atoms. 5. Compounds are formed by a combination of two or more different kinds of atoms.
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
According to Dalton what happens to atoms during a chemical reaction?
Combine with other atoms Separate from other atoms they are already attached to.
What major contribution did john Dalton made to the atomic theory?
Dalton's Atomic Theory 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) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms.
What are the theories of Dalton?
John Dalton was a chemist known for curiosity when it comes to the weather and atmosphere, thus giving birth to his atomic theory. DaltonÕs atomic theory can be divided into 4: Every matter in the world are made of atoms, atoms of an element are similar in properties and mass, a combination of two or more kinds of atoms forms compounds and a rearrangement in atom is called a chemical reaction.
Is calcium nitrate plus ammonium hydroxide a physical change?
No, it is a chemical change. Rearrangement of atoms to make different compounds is one way to define a chemical reaction.
What did Dalton's atomic theory propose about the atom?
The Law of Multiple Proportions
How did John Dalton explain a chemical reaction using his atomic theory?
Three laws during Dalton's time were the law of definite proportions, law of multiple proportions and law of conservation of mass. According to law of conservation of mass, there is no loss of mass during any chemical reaction. Dalton's proposition that atoms are not destroyed or invented. The atoms merely realign themselves in a chemical reaction; so there is no loss of mass. According to the law of multiple proportions, when 2 elements form more than 1 compound, the different masses of one element that combine with the other element are connected to each other in small whole ratios. For example, in the case of nitrogen dioxide and nitrogen monoxide. One atom of nitrogen combines with one atom of oxygen for nitrogen monoxide. One atom of nitrogen combines with two atoms of oxygen for nitrogen dioxide. In the case of law of definite proportions, it is stated that a chemical compound always has precisely the same proportion of elements in terms of mass. According to Dalton's atomic theory, matter consists of atoms and one type of atom is allocated for each element. Compounds were actually combinations of various kinds of atoms in fixed ratios.
How is the modern atomic theory is differ from the Dalton theory?
Dalton's Atomic Theory is as follows: 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) Compounds are formed by a combination of two or more different kinds of atoms. 4) A chemical reaction is a rearrangement of atoms. Dalton's atomic theory is correct in essence with a few exceptions to his rules: 1) Atoms are the smallest unit of mater that retain the physical and chemical properties of an element, however, they are divisible by non-chemical means. 2) All atoms of a single element contain the identical number of protons and electrons, however, their masses may vary with the number of neutrons in different isotopes (some of which are unstable and decay). For very basic purposes, Dalton's theory holds true.
