Answer:

Free Hotmal Suggested Sites Web Sice Gallery ring the number of owers Watering all of the rose bushes the same amount throughout the experiment Selecting a rose bush that will not be fertilized O 23 One neutron is added to the nucleus of an atom of carbon-12. In which of the following ways has the atom been changed? O It has an atornic number of 7 it bonds with different atoms It has a greater atomic mass O It has been changed to an ion 24 which of the following is the first step a researcher should take before experimentation begins? Apply the units of the sI system ment Answer- It has a greater atomic mass Reason: The total mass of an atoms is defined as the total number of neurtons and protons which further contribute to the total mass of an atom. In the above case one extra neutron added to the C-12 isotope then these will very minute changes in the atomic mass as Carbon mass still the same as 12 but few daltone of neutron weigth will be added to this which will be in decimals of C-12.
