A covalent bond means shared electrons between atoms. This is similar to kids sharing markers because the markers (electrons) are being shared between the kids (atoms). Covalent bonds are different than this metaphor because 1) the electrons are constantly moving about while the kids can steal and keep the markers and 2) the electrons and atoms are physically smaller
Answer:
An Atom.
Explanation:
An atom is the smallest particle of a chemical element that can exist. It the fundamental piece of matter. Therefore, splitting carbon into smaller pieces , the smallest piece that would still be called "carbon" would be an Atom of carbon. However, atom is also made of three subatomic particles called electrons, protons and neutrons.
Answer: nucleus
Explanation: the bigger the nucleus there more reactive the atom is
Answer: 
molecules of water are produced.
Explanation:
To calculate the moles :
The balanced chemical reaction is:
According to stoichiometry :
2 moles of 
produce = 3 moles of 
Thus 0.707 moles of will produce=
of
According to avogadro's law, 1 mole of every substance contains avogadro's number 
of particles.
Thus 1.06 moles of contains = 
molecules
