Answer: The stoichiometric coefficient for oxygen is .
Explanation:
A number present on the front of an atom, ion or molecule in a chemical reaction equation is called a stoichiometric coefficient.
For example,
Here, the stoichiometric coefficient for is 1, for is 1 and for is .
Thus, we can conclude that the stoichiometric coefficient for oxygen is .
Answer:
causes a substance to change from a liquid to a solid.
Explanation:
The correct answer is c.
answer b is incorrect <span />
Answer:
<em><u>Intermolecular forces determine bulk properties, such as the melting points of solids and the boiling points of liquids. Liquids boil when the molecules have enough thermal energy to overcome the intermolecular attractive forces that hold them together, thereby forming bubbles of vapor within the liquid.</u></em>
