Question

1. choose all that apply. select the five postulates proposed by dalton.. all atoms of all elements are identical. atoms do not differ from other atoms of different elements. atoms cannot be combined, separated, or rearranged in chemical reactions. atoms cannot be created or destroyed (law of conservation of mass) nor can they be divided into smaller particles. all matter is composed of extremely tiny particles called atoms. atoms of one element can combine in whole - number ratios with atoms of other elements to form compounds (law of multiple proportions). atoms can be combined, separated, or rearranged in chemical reactions. these reactions cause one or more substances to be converted into different forms. all matter can be divided infinitely and still be that matter. all atoms of a given element are identical. they have the same mass. however, atoms differ from other atoms in different elements by size, mass, and chemical properties.

Explanation:

Dalton's atomic theory postulates include: all matter is made of atoms; atoms of a given element are identical but differ from other - element atoms; atoms cannot be created, destroyed or divided; atoms can be combined, separated or rearranged in chemical reactions; atoms of different elements combine in whole - number ratios to form compounds.

Answer:

• Atoms cannot be created or destroyed (law of conservation of mass) nor can they be divided into smaller particles.
• All matter is composed of extremely tiny particles called atoms.
• Atoms of one element can combine in whole - number ratios with atoms of other elements to form compounds (law of multiple proportions).
• Atoms can be combined, separated, or rearranged in chemical reactions. These reactions cause one or more substances to be converted into different forms.
• All atoms of a given element are identical. They have the same mass. However, atoms differ from other atoms in different elements by size, mass, and chemical properties.
