Answer:
True.
Explanation:
The boiling point of acetone is 56°C while boiling point of 2-methyl propane is -11°C. Based on these values, <em>boiling point of acetone is much greater than the boiling point of 2-methylpropane. </em>
That could be because acetone has an electronegative atom (Oxygen) doing high intermolecular forces in this molecule while 2-methylpropane is an apolar molecule.
I hope it helps!
Probably NO2 because it includes Oxygen in the equation.
<span>If a solid forms when two ionic solutions are mixed together in a test tube, it is an indication of a chemical change
The precipitaion os the solid indicates that a new product has been formed which is not soluble.
When a solid ionic compound is put in water, the compound is dissolved by ionizing (the ions separate and remain in aqueous phase). If you combine two ionic solutions and see a solid precipiate is becasue the ions have combined and form a new compound which is not soluble.

Chemistry is the scientific discipline involved with elements and compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances
