Answer:
1. Atom absorbs energy from a source
2. Electron becomes unstable because it is quantized
3. Electron jumps to a higher energy level
4. Energy is released in the form of light
5. Electron falls to a lower energy level
Explanation:
1. carbon cycle
all of the physical processes and chemical reactions that result in the movement of carbon between the biosphere (living forms) and the geosphere (water, earth, and atmosphere)
Carbon cycle is the cyclic movement of carbon in various form on earth. This process entails both physical and chemical processes that ensures that carbon moves in different spheres of the earth. Carbon is one of the most important element in life. It is the building block of most organic processes on earth.
2. carbon footprint
a calculation that considers an individual's contribution to the process of global warming based on activities leading to greenhouse gas production
Carbon footprint is important in mapping the quota of carbon emitted into the atmosphere
It is the amount of greenhouse gases contributed into the atmosphere by individuals.
3. global warming
an overall increase in world temperatures that may be caused by additional heat being trapped by greenhouse gases
It is the overall increase in global temperature. It has severe consequences.
Global warming results when greenhouse gases in the atmosphere traps outgoing radiation in an anomalous way.
4. greenhouse gas
components of the air mixture that trap infrared (heat) energy
Greenhouse gases are gases that prevents long wave radiation from leaving the earth surface. They absorb the gases in turn, warming occurs on earth.

Answer:
3Ba(OH)₂ + 2H₃PO₄ → Ba₃(PO₄)₂ + 6H₂O
Explanation:
Neutralization reaction:
When an acid and base react they form water and salt.The reaction is called neutralization reaction.
General equation:
HX + BOH → BX + H₂O
From given reaction equations only option C is correct because only this reaction gives salt and water.
Chemical equation:
3Ba(OH)₂ + 2H₃PO₄ → Ba₃(PO₄)₂ + 6H₂O
Barium hydroxide is acting as a base. H₃PO₄ is an acid. Both these reactants react to form salt which is barium phosphate and water.
Other options are incorrect because non of these reaction produced salt and water. So option A is correct.
