Laws of Multiple and Definite Proportions and Conservation of Mass 1. Dalton's atomic theory explained the observation that the percentage by mass of the ... The difference in mass percentages of the reacting carbon and oxygen between the two experiments is best supported by: (A) The Law of Multiple Proportions (B) The Law of Definite CompositionEmulsion of biopolymers with a constant weight ratio percentage of 8.00% (w/w, coating material/sidat eel meat) and four different proportions of MD and GA were prepared using a homogenizer, followed by freeze-drying. The laws of physics dictate that if you put a conducting material in a changing magnetic field electric currents will arise and those electric currents will then create a secondary magnetic field. This secondary field is often referred to as the induced magnetic field because it is induced by the primary field of the doorway.

Protons have a charge of +1, and a mass of approximately 1 atomic mass unit (amu). Elements differ from each other in the number of protons they have, e.g. Hydrogen has 1 proton; Helium has 2. The neutron also is located in the atomic nucleus (except in Hydrogen). The neutron has no charge, and a mass of slightly over 1 amu.
