The arrow shows that the bond between the chlorine atom and the fluorine atom is the electrons in the bond are pulled and the chlorine atom is : ci - f:

Explanation:

When electrons are shared by two atoms then it results in the formation of a covalent bond.

Both chlorine and fluorine are non-metals and are electron deficient in nature. Therefore, when both of them combine then they tend to share the electrons and thus they form covalent bond.

Since fluorine is more electronegative than chlorine, therefore, a partial positive charge will develop on chlorine and partial negative charge will develop on fluorine atom.

Thus, we can conclude that the arrow shows that the bond between the chlorine atom and the fluorine atom is covalent. The electrons in the bond are pulled towards fluorine atom, and the chlorine atom is partially positive.

The answer choices for the first part of the questions are polar, ionic, and nonpolar . Out of those 3 which is the correct answer ? , because " Covalent " is not a choice .

Explanation:

n+h→nh3

we must remember that nitrogen and hydrogen are both diatomic molecules in their standard gas form. this adjusts the equation to

n2+h2→nh3

now we need to adjust coefficients in order to balance the atoms on each side of the equation. currently we have 2 atoms of nitrogen and 2 atoms of hydrogen on the reactant side and 1 atom of nitrogen and 3 atoms of hydrogen on the product side.

we can balance the hydrogens by placing a coefficient of 2 in front of ammonia and a coefficient of 3 in front of the hydrogen.

n2+3h2→2nh3

this gives us 6 hydrogen on each side and coincidentally the nitrogens now equal 2 on each side.
