There are 6.02 × 10²³ formula units of CaCl2 in 111 g CaCl2. Details about formula units can be found below.
<h3>What is a formula unit?</h3>
Formula unit refers to the empirical formula of an ionic compound for use in stoichiometric calculations.
According to this question, there are 111g of CaCl2. The formula units can be calculated by multiplying the number of moles by Avogadro's number.
no of moles in CaCl2 = 111g ÷ 111g/mol = 1mol
Formula units of CaCl2 = 1mol × 6.02 × 10²³ = 6.02 × 10²³ formula units.
Therefore, there are 6.02 × 10²³ formula units of CaCl2 in 111 g CaCl2.

Answer:
Carbon
Explanation:
The field of organic chemistry is the field of the study of the compounds of carbon mostly with hydrogen but they can contain the presence of other atoms such as oxygen, nitrogen, sulfur even metals such as lithium. It studies the structure, properties, synthesis and reactions of these compounds. The field of organic chemistry is the field of living organisms as they are mostly are formed by organic compounds hence its name organic.
Answer:
Niels Bohr The electron in a Hydrogen atoms can only circle the nucleus in certain paths or orbits.
Answer: Oxidation is defined as the reaction in which there is loss of electrons. It is accompanied by increase in oxidation number.
Zinc in solid state has oxidation number of zero and on losing electrons changes to 
with oxidation number of +2.
Reduction is defined as the reaction in which there is gain of electrons. It is accompanied by decrease in oxidation number.
Hydrogen ions with +1 oxidation state gains electrons and converts to molecular hydrogen with oxidation state of zero.
In the given redox reaction, both oxidation and reduction takes place. They go hand in hand.
Zinc converts to and gets oxidized. 
gains electron and convert to 
.
