Answer:
The order in which the orbitals is filled is 1s-2s-2p-3s-3p-4s-3d-4p-5s-4d-5p-6s-4f-5d-6p-7s-5f-6d-7p
Explanation:
S orbitals each hold two electrons, p orbitals hold 6, d orbitals hold 10, and f orbitals hold 14. 1s has the least energy and 7 p has the greatest energy, so the order in which they are filled is listed above.
Answer:
MSDS -- Material Safety Data sheet
Explanation:
The full form of MSDS is Material Safety Data sheet. A Material Safety Data Sheet is a document which contains the information related to the potential hazards (fire or reactivity and environmental and health ) and includes how to work or use the chemical product safely.
It is regarded as an essential starting point for development of the complete health as well as safety program. MSDS also contains other information such as the use of the chemical, its storage and also handling and the emergency procedures that are related to the hazards of the material.
Answer:
A barometer is an instrument used to measure air pressure and track weather systems. The most common unit of measurement used in barometers is the millibar (mb).
Explanation:
If it is saturated compound then we can calculate the double bond equivalent which will be equal to the number of rings in the compound
the double bond equivalent can be calculated using following formula
Where
H = number of Hydrogen atoms
C = number of carbon atoms
X= number of halogen atoms
N = number of nitrogen atoms
DBE = (10 + 1 - 16 / 2 ) = 3
Hence there are three rings in the compound
The conversion factor between the unit in meter and that of kilometer is that, 1 kilometer = 1000m
For the given above,
(288 m³) x (1 km / 1000 m)³ = 2.88 x 10^-7
Thus, 288 m³ is also equal to 2.88 x 10^-7 km³.
