Ionic or covalent C2H5OH
Afina-wow [57]

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.

\begin{array}{ccc}\textbf{Bond} & \textbf{$\Delta$EN} & \textbf{Polarity}\\\text{C-C} & 2.55 - 2.55 = 0.00 & \text{Nonpolar covalent}\\\text{C-H} & 2.55 - 2.20 = 0.35 & \text{Nonpolar covalent}\\\text{C-O} & 3.44 - 2.55 = 0.89 & \text{Polar covalent}\\\text{O-H} & 3.44 - 2.20 = 1.24 & \text{Polar covalent}\\\end{array}

No bond has a large enough ΔEN to be ionic.

C₂H₅OH is a covalent molecule.

Consider a carbon atom that is sp hybridized. Indicate how many of each orbital exist on this carbon atom by sorting each orbita
Karo-lina-s [1.5K]

Explanation:

It is known that atomic number of carbon is 6 and its electronic configuration is 1s^{2}2s^{2}2p^{2}. 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.

Write the complete balanced equation for the following reaction: Al + Fe(NO2)2 yields Fe + Al(NO2)3
hodyreva [135]
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 :)
