Compare a crystal lattice with a molecule. what does the formula unit al(oh)3 tell you about the compound aluminum hydroxide?

A crystal lattice is a solid in which the particles are arranged in a regular, repeating pattern.

A molecule is a discrete unit of atoms that is bonded together.

Many ions come together to form a crystal.

The formula unit of an ionic compound represents the smallest ratio of ions in the crystal.

The lattice of aluminum hydroxide has three OH- ions for every Al3+ ion.

Explanation:

any of those are right

the answer is na (sodium)

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
