Answser: the representative unit of carbon dioxide is the molecule CO₂.


Justification:


1) carbon dioxide is made of one atom of carbon and two atoms of oxygen chemically bonded by covalent bonds.


2) A molecule is formed when two or more atoms are bonded by covalent bonds.


3) Some other examples of molecules are: water (H₂O), oxygen (O₂), the fats, the carbohydrates, glucose.


4) The term molecule is reserved for atoms bonded by covalent bonds, so ionic compounds like NaCl, are not named molecules. NaCl is told to represent a formula unit instead of a molecule.

The expected value for a chemical equation is 47g of water, after an experiment you find that you have 2.58 moles of water. What
strojnjashka [21]
<h3><u>Answer</u>;</h3>

Actual yield = 46.44 g

<h3><u>Explanation;</u></h3>

1 mole of water = 18 g/mol

Therefore;

The experimental yield = 2.58 moles

equivalent to ; 2.58 × 18 = 46.44 g

The theoretical value is 47 g

Percentage yield = 46.44/47 × 100%

                             = 98.8%

The questions asks for actual yield = 46.44 g
