Just finished the test.
Atoms cannot be subdivided into smaller particles - incorrect as you can subdivide atoms into protons, neutrons and electrons
Boiling point.
It is the temperature at which the vapor pressure of the liquid equals the vapor pressure of tha atmosphere that surrounds it, which permit to defeat the attraction among the molecules in the liquid phase and pass to the gas phase.

Explanation:
Resonance is a valence bond terminology which is used to describe a situation in which a single structure is not able to fully describe the nature of bonding in a molecule.
In such cases, we invoke more than one structure. Each structure contributes significantly to our understanding of the nature of bonding in the molecule under consideration and these structures are called canonical or resonance structures.
The real structure of the molecule is somewhere in between these structures - a resonance hybrid.
For ozone, two equivalent structures can be used to describe the bonding in the molecule. These structures are equivalent as shown in the mage attached. We can see from these structures that the bond order in ozone is 1.5(one and half bonds)
Answer:
Carbon Cycle
Steps of the Carbon Cycle
- CO2 is removed from the atmosphere by photosynthetic organisms (plants, cyanobacteria, etc.) and used to generate organic molecules and build biological mass.
- Animals consume the photosynthetic organisms and acquire the carbon stored within the producers.
- CO2 is returned to the atmosphere via respiration in all living organisms.
- Decomposers break down dead and decaying organic matter and release CO2.
- Some CO2 is returned to the atmosphere via the burning of organic matter (forest fires).
- CO2 trapped in rock or fossil fuels can be returned to the atmosphere via erosion, volcanic eruptions, or fossil fuel combustion.
Nitrogen Cycle
Steps of the Nitrogen Cycle
- Atmospheric nitrogen (N2) is converted to ammonia (NH3) by nitrogen-fixing bacteria in aquatic and soil environments. These organisms use nitrogen to synthesize the biological molecules they need to survive.
- NH3 is subsequently converted to nitrite and nitrate by bacteria known as nitrifying bacteria.
- Plants obtain nitrogen from the soil by absorbing ammonium (NH4-) and nitrate through their roots. Nitrate and ammonium are used to produce organic compounds.
- Nitrogen in its organic form is obtained by animals when they consume plants or animals.
- Decomposers return NH3 to the soil by decomposing solid waste and dead or decaying matter.
- Nitrifying bacteria convert NH3 to nitrite and nitrate.
- Denitrifying bacteria convert nitrite and nitrate to N2, releasing N2 back into the atmosphere.
Oxygen Cycle
Oxygen is an element that is essential to biological organisms. The vast majority of atmospheric oxygen (O2) is derived from photosynthesis. Plants and other photosynthetic organisms use CO2, water, and light energy to produce glucose and O2. Glucose is used to synthesize organic molecules, while O2 is released into the atmosphere. Oxygen is removed from the atmosphere through decomposition processes and respiration in living organisms.
