Answer:
Carbon-carbon bonds. (Ans.A).
Explanation:
None covalent bonds are different from covalent bonds, they are not formed by the sharing of electrons which is present between the bonded atoms. They are formed by the help of electrostatic attraction or some other type of interaction found between the ions or atoms.
A carbon-carbon bond is known as a covalent bond, and they are formed with the help of the sharing of electrons which is found between the two carbon atoms. Both carbon atoms have 4 electrons for bonding.
Fe2O3 + 3CO --------> 2Fe + CO2
1 : 3 : 2 : 3
13.3 <--- 40 ------> 26.6 ---> 40 ( mol)
n = m/M
m CO2 = n.M = 13.3 . 40 = 532 ( g)
p/s : i hope that this will help ( cause i'm not really good at english :}}} )
