Covalent and ionic bonds are two different types of chemical bonding. Covalent bonds involve the sharing of electrons between 2 atoms while ionic bonds involve the complete transferring of electrons from one atom to another. Covalent bonds usually form between two nonmetals while ionic bonds usually form between a metal and a nonmetal.
I hope this helps. Let me know if anything is unclear.
The answer should be D, cells can only create an identical copy of the original cell.
Answer:
When you place the north pole of one magnet near the south pole of another magnet, they are attracted to one another.
Explanation:
Answer:
Mass = 157.5 g
Explanation:
Given data:
Mass of CO needed = ?
Mass of Fe formed = 209.7 g
Solution:
Chemical equation:
3CO + F₂O₃ → 2Fe + 3CO₂
Number of moles of Fe:
Number of moles = mass/ molar mass
Number of moles = 209.7 g/ 55.85 g/mol
Number of moles = 3.75 mol
Now we will compare the moles of iron and carbon monoxide.
Fe : CO
2 : 3
3.75 ; 3/2×3.75 = 5.625 mol
Mass of CO:
Mass = number of moles × molar mass
Mass = 5.625 mol × 28 g/mol
Mass = 157.5 g
