Answer:
a.Carbon :proton number =6
electron number =6
b. Fluorine: proton number=9
electron number =9
c. tin: proton number=50
electron number =50
d. nickel:proton number=28
electron number =28
Explanation:
In the neutral state of an atom the number of protons is always equal to the number of electrons and that whats makes it electrically neutral as the positive charges of protons balances the negative charges of electrons.
Answer:
The highest biogenic silica accumulation rates in this area are observed in the South Atlantic, with values as large as 53 cm. kyr−1 during the last 18,000 yr. Further, extensive biogenic silica accumulation has been recorded in the deep-sea sediments of the Bering Sea, Sea of Okhotsk, and Subarctic North Pacific.
Explanation:
C₂H₂ + O₂ --> CO₂ + H₂O
when balanced
2C₂H₂ + 5O₂ --> 4CO₂ + 2H₂O
