The ideal gas under STP is 22.4 L/mol. While the gas has a rule of P1V1/T1=P2V2/T2. So the volume under 101 kPa and 273 K is 0.2*22.4=4.48 L.
Answer:
energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. ... For example, any given body has kinetic energy if it is in motion.

Explanation:
The distance to school is 14.4 kilometers which are equal to 14400 meters.
Amy takes 40 minutes which are equal to 40 × 60 = 2400 seconds to arrive at school.
Bill takes 40 + 20 = 60 minutes which are equal to 60 × 60 = 3600 seconds to arrive at school.
Amy’s average speed = distance (m) / time (s)
Amy’s average speed = 14400 m / 2400 s = 6 m/s
Bill’s average speed = 14400 m / 3600 s = 4 m/s
How much faster (in meters/second) is Amy’s average speed for the entire trip?
Amy’s average speed - Bill’s average speed = 6 m/s - 4 m/s = 2 m/s

Answer:
3Mg(OH)2 + 2H3PO4 = Mg3(PO4)2 + 2H3O
Explanation:
Let's check Electronic configuration of N in ground state
In hydrogen case
Hence Hybridization
Structure is tetrahedral .
Spare way:-
- Bond pairs==3=>Bonding electrons=6
- Lone pair=1=>Anti bonding electrons=2
Hybridization
