Answer is: The breakdown of ozone is an endothermic process.
There
are two types of reaction: endothermic reaction (chemical reaction that
absorbs more energy than it releases) and exothermic reaction (chemical
reaction that releases more energy than it absorbs).
Ozone has lower energy than molecular oxygen (O₂) and oxygen atom, so ozone need energy to break bond between ohygen atoms.
The answer to your question is A. the wind exerts a force on the leaf causing its motion to change
Ionic Bonds have a Lower melting and Covalent have higher.
Answer:
See explanation
Explanation:
Many organic compounds have low melting points. This is due to the fact that many of these compounds are non polar.
However, compound X is slightly polar but still has a melting point which is far less than that of sand composed of a high melting point inorganic material.
Since sand has a much higher melting point compared to compound X, the researcher need not be worried that sand was spilled into his beaker.
