Answer:
b. A mole of chlorine gas contains 2 (6.02 * 10^23 ) atoms.
c. A mole of carbon dioxide contains two moles of oxygen molecules (CO2)
e. A mole consists of the number of particles in exactly 12g of naturally occurring carbon.
Explanation:
A mole of oxygen gas (O2) contains 2 (6.02 * 10^23) atoms
A mole of Ammonia gas (NH3) has a mass of 17.031g/mol
A mole is defined as the unit used in measurement of the amount of substances in the International System of Units.
A mole was initially defined as the number of particles in exactly 12g of naturally occurring carbon.
Therefore, options b, c and e are correct

Answer: the correct answer is : too many fish caused an imbalance in the ecosystem, so the food web was affected.
Explanation:
Due to a difference in electronegativity between the two atoms. The atom with more electronegativity will attract the electrons to itself more than one with a lower electronegativity which will create a slight negative charge around the more electronegative. I hope this helps. Let me know if anything is unclear.
