Answer:

1.31×10^-16moles

Explanation:

If 1 mole of carbon contains 6.02×10^23 carbon atoms (Avogadro's number)

X moles of carbon contain 7.87×10^7 carbon atoms

X = 7.87×10^7/6.02×10^23

X= 1.31×10^-16moles

Note that 1 moles of any substance contains Avogadro's number of elementary entities (atoms, ions, molecules etc)

In creating a covalent bond, it would be best to bind sulfur to:
valentina_108 [34]
Sulfur is best to bind with oxygen. A covalent bond is a bond between two nonmetal elements. Aluminum is a metalloid and sodium is a metal. Both can't be bonded with sulfur. Neon isn't a metal but is a group 18 element, it's a noble gas. And a noble gas cannot be combined with any element because it already achieved a total of 8 valence electrons. Oxygen on the other hand can be bonded with sulfur since both are non metals

How did atomic theory develop and change?
Agata [3.3K]
The atomic theory started with Democritus, who stated that all space was made up of indivisible particles called atoms, though Aristotles refuted that statement by saying that matter didn’t exist, he believed in the four elements: air, fire, water, and earth. Then came Dalton, who revived Democritus’s ideas and proposed the law of multiple proportions, he revived the idea that all space was made of atoms. Soon after, J.J Thompson discovered the electron by using cathode rays. Max Planck developed the quantum theory by stating that electromagnetic radiation could only be emitted in quantized form (later called quanta). Einstein furthered this idea with studies of light. Robert Millikan eventually measured the charge of a single electron. Ernest Rutherford used a gold foil experiment and discovered the nuclei, considering his alpha particles were deflected by some object. Niels Bohr made the atomic model with electrons spinning around an atom’s nucleus, Erwin Schrodinger describes how electrons have wave like properties. James Chadwick then discovers the neutron!

There ya have it!
