i need all the answers
I apologize for the confusion. Here are the answers:
a. Dalton and Macie determine that a chemical reaction must have taken place. When this kind of change occurs, atoms must rearrange.
b. The evidence that was useful to Dalton and Macie in answering question a is that one of the substances formed had a new property.
no all them for part b
what about One of the substances formed had a new property.
I apologize for the omission. The evidence that was useful to Dalton and Macie in answering question a is that one of the substances formed had a new property.
