Answer:
Covalent
Explanation:
A molecule of C₂H₅OH has C-C, C-H, C-O, and O-H bonds.
A bond between A and B will be ionic if the difference between their electronegativities (ΔEN) is greater than 1.6.

No bond has a large enough ΔEN to be ionic.
C₂H₅OH is a covalent molecule.
Answer:
One mole of CO2 has mass of 44 g and 32 g of O2. So 16 g of O2 have 22 g of CO2 or 0.5 moles of it.

Explanation:
Explanation:
It is known that atomic number of carbon is 6 and its electronic configuration is
. This means that in its neutral state it contains 2 electrons in its s-orbital and 2 electrons in its p-orbital.
After excitation there will be one electron present in its s-orbital and three electrons present in p-orbital.
Therefore, after the hybridization there will be in total 2 sp hybrid orbitals, 2 p-orbitals and zero s-orbital.
The reactants has 2 NO2 and the product has 3. So we need to make sure we have 6 on each side.
Al + 3Fe(NO2)2 -> Fe + 2Al(NO2)3
This leaves us with us just to balance the Fe And Al
2Al + 3Fe(NO2)2 -> 3Fe + 2Al(NO2)3
Hope this helped :)
