Question

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

Explanation:

Dalton's atomic theory postulates that all matter is made of atoms, atoms of a given element are identical, atoms can't be created/destroyed or divided further, atoms can combine/separate/rearrange in chemical reactions, and atoms combine in whole - number ratios to form compounds.

Answer:

• All matter is composed of extremely tiny particles called atoms.
• Atoms cannot be created or destroyed (law of conservation of mass) nor can they be divided into smaller particles.
• 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.
• Atoms can be combined, separated, or rearranged in chemical reactions. These reactions cause one or more substances to be converted into different forms.
• Atoms of one element can combine in whole - number ratios with atoms of other elements to form compounds (law of multiple proportions).
