Write the name for the ionic compound bal2

Barium iodide

Explanation:

barium iodide is ionic compound. it is formed by the barium metal and halogen element iodine.

Barium is present in group two have two valance electrons.

Iodine is present in group seventeen and have seven valance electrons.

Iodine needed one electron two complete the octet.

That's why two atoms of iodine combine with one atom barium and form ionic compound called barium iodide.

Ba⁺²  I₂²⁻

The overall charge is equal cancel the effect of each other and form over all compound neutral.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
