The empirical formula is CrCl₃.
Explanation:
To find the empirical formula we use the following algorithm.
We divide each percentage by the atomic weight of each element:
for Cr 32.8 / 52 = 0.63
for Cl 67.2 / 35.5 = 1.89
The result will be divined by the smallest number:
for Cr 0.63 / 0.63 = 1
for Cl 1.89 / 0.63 = 3
The empirical formula is CrCl₃.

Answer:
he line begins at boron (B) and extends down to polonium (Po). Elements to the left of the line are considered metals. Elements just to the right of the line exhibit properties of both metals and nonmetals and are termed metalloids or semimetals. Elements to the far right of the periodic table are nonmetals.
Answer:
The water is universal solvent because it is a polar molecule.This have hydrogen bonding in which hydrogen molecule have positive charge and oxygen molecule have negative charge because electro negativity of oxygen molecule is higher than hydrogen molecule that is why it pull the hydrogen molecule and formed a polar molecule.That is why is also known as universal solvent.
<span>It contains 6.02mc001-2 particles of a given substance</span>
True
It’s true because models are based on real world problems to help grasp a understanding of the problem
