Answer:
sp atomic orbital
Explanation:
CO has a triple bond, which is composed of one sigma bond and two pi bonds. Pi bonds are formed using one p orbital from each atom, so the carbon atom must have two unhybridized p orbitals in order to form two pi bonds. The other s and p orbitals that it has are hybridized together to form two sp orbitals. One of the sp orbitals is used in the sigma bond and the other holds the lone pair.
Answer: Hurricane is not a man-made environmental change.
Explanation:
Changes which take place naturally in the environment without any force or work done by man towards causing that change are called non-man made environmental changes.
For example, hurricane is a natural environment change because a hurricane is formed moist and warm air above water surface of sea, oceans or rivers begin to rise.
This rising air is replaced by the cooler air present in the atmosphere. The continuation of this process leads to the formation large clouds and thunderstorms which occurs in the form of hurricane.
Whereas pollution is caused by vehicles driven by man, from chimneys of factories etc. So, it is a man-made environmental change.
Chemical spill can occur due to mishandling by man in laboratories or chemical labs.
Deforestation also occurs by man as they cut the trees for various needs to theirs.
Thus, we can conclude that hurricane is not a man-made environmental change.
Isotopic notation of phosphorus-29 is
Explanation:
- Isotopes are atoms with equal number of protons but different number of neutrons at its nucleus.
- The isotopic notation for any element can be written as where X represents the chemical symbol ,A represents mass number and Z represents atomic number
- The atomic number for phosphorus is 15
- Isotope's mass number for phosphorus-29 is 29
- The chemical symbol for phosphorus is P
- Hence Isotopic notation is
- Number of neutrons = 29-15 =14
- Number of protons=atomic number =15
Explanation:
they are located in the neucleus
