Count the number atoms in the following compound
3 Al(OH)3
AL=
O
H=
1
2

Explanation:

Let us look closely at the compound, Count the number atoms in the following compound Al(OH)3;

We shall considered the number of each atom present in this compound.

There is one atom of aluminum present

There are three atoms of oxygen present

There are three atoms of hydrogen present

Hence, there are a total of seven atoms of different elements in the compound.

there are no statements provided but here is why:

sulfur belongs to group 16 because it can be found in nature whether it is in a free or combined state.

hope this

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.
