Question

1. choose all that apply. which five postulates were proposed by dalton? atoms of one element can combine in whole - number ratios with atoms of other elements to form compounds (law of multiple proportions). 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. all matter is composed of extremely tiny particles called atoms. all matter can divide infinitely and still be that matter. all atoms of all elements are identical. atoms do not differ from other atoms of different elements. atoms can be combined, separated, or rearranged in chemical reactions. these reactions cause one or more substances to be converted into different forms. atoms cannot be combined, separated, or rearranged in chemical reactions.

Explanation:

Dalton's atomic theory postulates include that all matter is made of atoms, atoms of a given element are identical, atoms combine in whole - number ratios to form compounds, atoms can be combined, separated or rearranged in chemical reactions, and atoms cannot be created or destroyed in chemical reactions. The statements about atoms being able to divide infinitely and all atoms of all elements being identical are incorrect according to his theory.

Answer:

• 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 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.
• All matter is composed of extremely tiny particles called atoms.
• Atoms can be combined, separated, or rearranged in chemical reactions. These reactions cause one or more substances to be converted into different forms.
• Atoms cannot be created or destroyed (law of conservation of mass) nor can they be divided into smaller particles.
