Answer:
C.) The coefficient of iodine is 4, oxygen is 9, and the product is 2
Explanation:
An equation is balanced when there is an equal amount of each element on both sides of a reaction. If the amounts are unequal, you can modify the amount of molecules by adding coefficients.
The unbalanced reaction:
I₂ + O₂ -----> I₄O₉
<u>Reactants</u>: 2 iodine, 2 oxygen
<u>Products</u>: 4 iodine, 9 oxygen
The balanced equation:
4 I₂ + 9 O₂ -----> 2 I₄O₉
Reactants: 8 iodine, 18 oxygen
Products: 8 iodine, 18 oxygen
Remember, coefficients are the numbers placed in front of the molecular formulas. As such, the coefficient of iodine is 4, oxygen is 9, and the product is 2.
The answer would be B. <span>One atom of sodium and one atom of fluorine</span>
The genus is a lower classification level that lies below family and above species . Species is the fundamental category of closely related organisms that lies below the genus .
The molar mass of 
is 86.02 g/mole
.
<h3><u>
Explanation:</u>
</h3>
The molar mass of a chemical compound is represented as the mass of a unit of that compound separated by the number of substances in that unit, measured in moles. The molar mass is a volume, not molecular, the property of a substance.
The molar mass is a percentage of various examples of the compound, which usually change in mass due to the appearance of isotopes.
From the below attached table, the Molar mass of is 86.0108 g/mol.
