Answer:
Some major chemical properties include flammability, toxicity, heat of combustion, pH value, rate of radioactive decay, and chemical stability.
Explanation:
I searched this up hopefully this helps!
There are different types of chemical bonds. These are difficult to break and therefore, it is also hard to change. The reason why it's difficult to discover superiority of nature is due to its natural attraction between atoms, ions or molecules that cannot be revoked by man.
Sodium is not a macromolecule hence it does not contain any calories.
<h3>Does sodium contain calories?</h3>
The term calorie is a unit of energy. We often us the term to describe the amount of energy that is contained in each kind of food. The higher the calories, the greater the energy that the food contains.
Calories can only be contained by macromolecules such as proteins, carbohydrates, fats etc. Sodium is not a macromolecule hence it does not contain any calories at all hence the classmate is wrong.

the reactions catalyzed by hexokinase, phosphofructokinase, and pyruvate kinase
Explanation:
Answer:
C. Their properties change completely.
Explanation:
The electron configurations of the elements show a periodic variation with increasing atomic number. Consequently, there are also periodic variations in physical and chemical behavior.
When atoms interact to form a chemical bond, they combine in order to <u>achieve a more stable electron configuration.</u> As a consequence, the compounds formed exhibit completely different properties.
For example, when solid magnesium burns in air, it forms both magnesium oxide and magnesium nitride, which are gases.
