An atom is the smallest unit of ordinary matter that forms a chemical element.
oxygen, carbon, hydrogen, nitrogen, calcium, and phosphorus.
N₂
Explanation:
The molecule with the shortest bond length is nitrogen gas N₂ because it has a triple bond between the covalently bonded atom.
- Molecules with more number of bonds are usually stronger.
- The bond length is the average distance between two nuclei that are bonded in a molecule.
- Single bonds are usually very long and relatively weaker in nature. They easily broken and forms between atoms that are large in size because their nuclei is far from each other.
- Double bonds are stronger than single bonds and longer in nature.
- Triple bonds such as seen in Nitrogen gas are very strong bond types. They are the shortest.

<span>There are currently a number of active and erupting volcanos. I believe that they are contributing to global warming and man is also contributing to global warming. We are already seeing melting of polar ice and polar bears are being threatened because their environment is changing and they are having a difficult time adapting. I come from Hawaii which has an active volcano. The volcano is located on the island of Hawaii where it has already claimed hundreds of miles of homestead. It is also flowing into the ocean. I live on the island of Oahu and often times the volcanic ash (called Vog) is carried over in the southern winds. The most serious affect is on the lungs and eyes. I have trouble breathing when Vog comes and I feel fatigued. I believe long term volcanic eruptions will change our world for the worse along with other contributors to global warming.</span>
Given: C3H8(g) + O2(g) ----> CO2 (g) + H2O (g)
Step : Put a 3 in front of CO2 (g) to balance C
=> C3H8(g) + O2(g) ----> 3CO2 + H2O to balance H
Step 2: Put a 4 in front of H2O
=> C3H8 (g) + O2(g) -----> 3CO2 (g) + 4H2O (g)
Step 3: Given that there are 3*2 + 4 = 10 O to the right side, put a 5 in front of O2 to balance O:
=> C3H8(g) + 5O2(g) -----> 3CO2(g) + 4H2O(g)
You can verify that the equation is balanced.
So, the answer is that the coefficient in front of O2 is 5.
