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.
Is this an example of chemical reactions Energy is created as atoms are destroyed in chemical reactions?
No Energy can not be created or destroyed, it can only change form Matter cannot be created or destroyed, it can only change form. -- - -- Like stated above, energy can't be destroyed nor created. Only harnessed to only than be used and changed in form. Matter however CAN be destroyed, its exactly what an atomic bomb, hydrogen bomb or nuclear reaction plant does; annihilates molecules harnessing its potential energy. The law of conservation basically states that you either have matter or you have energy.
What are the postulates in Dalton's atomic theory 45k?
All elements are made of tiny indivisible particles called atoms.All atoms of a given element are alike but the atoms of one element differ from the atoms of every other element.Atoms are not created, destroyed or converted into other kinds of atoms during chemical reactions. They are simply rearranged into new compounds.Compounds result from the chemical combination of a specific ratio of atoms of different elements.(These are loose interpretations of his original five statements)
What are the main ideas of Dalton?
1) All matter is made of atoms. 2) Atoms of a given element are identical in size, mass and chemical 3) Atoms of different elements have different masses and properties. 4) Compounds are formed by a combination of two or more different kinds of atoms. The elements subdivided, created, or destroyed, but merely rearranged in their compounds with other elements. They can be combined, separated, or changed in the way in which they are arranged.
What did Henry Moseley change about the periodic table?
Henry Moseley discovered a relation between the atomic number and the X-ray wavelength of a given chemical element; this was a physical confirmation of the periodic table and the order of elements in the table.

How is mosley's basics for arranging the elements different from mendeleeve's?
Dmitri Mendeleev created and sorted the periodic table by atomic mass. When years later Mosley rearranged the table and sorted it by Atomic number.
What are postulates in Daltons atomic theory?
* All elements are made of tiny indivisible particles called atoms. * All atoms of a given element are alike but the atoms of one element differ from the atoms of every other element. * Atoms are not created, destroyed or converted into other kinds of atoms during chemical reactions. They are simply rearranged into new compounds. * Compounds result from the chemical combination of a specific ratio of atoms of different elements.

According to Dalton what happens to atoms during a chemical reaction?
Combine with other atoms Separate from other atoms they are already attached to.
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 are the parts of atomic theory?
There are five parts to The Atomic Theory: 1.All matter is composed of extremely small particles called atoms. 2. Atoms of a given element are identical in size, mass, and other properties; atoms of different elements differ in size, mass, and other properties.' 3.Atoms cannot be subdivided, created or destroyed. 4.Atoms of different elements combine in simple whole-number ratios to form chemical compounds. 5.In chemical reactions atoms are combined separated or rearranged.

How does Antoine lavoisier relate to the atomic model development?
Lavoisier made the atomic theory of matter, stating that matter is not destroyed or created, just changes form.

Is it true that during chemical changes atoms are rearranged and different kind of matter form?
Yes, in chemical reactions the fundamental structure of the molecules (i.e., the arrangement of the atoms) changes. This differs from a physical reaction, in that in a physical reaction, only superficial traits of the substance change. A good rule of thumb for determining whether something is a physical or chemical reaction is that physical reactions are easily reversible (e.g., freezing/melting water), while a chemical reaction is not really reversible (e.g., cooking/uncooking a steak).
What city was destroyed by an atomic bomb in 1945?
Hiroshima and Negasaki in Japan were the two cities destroyed my an atomic bomb in 1945.
