B because isotopes have the same number of protons but a different number of neutrons
Sulfur is the element used to cross-link the hydrocarbon chains when natural rubber undergoes vulcanization.
The invention relates to cross-linking hydrocarbon polymers with aromatic polyazides in the presence of sulfur. It has been discovered that hydrocarbon polymers can be cross-linked when heated with aromatic polyazides.
Answer:
B) microscopic
Explanation:
A scanning tunneling microscope allows imaging of microscopic particles.
the number is the mass number
the mass number is the number of nucleons (total number of protons and neautrons in the nucleus) so in hydrogen-3 there are 3 nucleons and as hydrogen has 1 proton, there are 2 neutrons
carbon 12 has 12 nucleons (6 protons and 6 neutrons) and carbn 13 has 13 nucleons (6 protons and 7 neutrons)
