The balanced reaction
that describes the reaction between carbon monoxide and oxygen to produce
carbon dioxide is expressed co(g)+ ½o2(g) <span>→ </span>co2(g). The heat of combustion is 67.6 kcal per mole CO. We are given with 14 grams CO. Convert this to mole equal to 0.5 mole. Hence the total heat is 33.8 kcal.
When an atom of the element lithium (Li) transfers an electron to an atom of the element fluorine (F), then the bond results between the atoms is ionic bond.
<h3>what is chemical bond? </h3>
A chemical bond is defined as the bond which holds atoms together in molecules.
Bonds arise due to the electrostatic forces present between positively charged atomic nuclei and negatively charged electrons.
<h3>Types of chemical bond</h3>
- Ionic bond
- Covalent bond
- Coordinate bond
<h3>What is Ionic bond ? </h3>
Ionic bond is defined as the transfer of electron from one atom to another atom.
Since, electron transfer from lithium to fluroine. Thus lithium get positive charge and fluorine occupy negative charge.
Thus, the bond form between lithium atom and fluorine atom is ionic bond.

Answer:
Because if you use pen, your chromatography will separate also the colors of the pen and not just your sample.
Explanation:
The pencil since is carbon as simple element, is solid and is not dissolved in solvents like commonly are used in paper chromatography, it will not interrupt the separation of the compounds in your mixture, otherwise, your results will be confuse because you are not sure if the spots that you observe is due to the ink pen or due to the mixture that you want to separate.
