BF3 has a boron atom with three outer-shell electrons in its ground state and three fluorine atoms containing seven outer electrons. Further, if we observe closely, one boron electron is unpaired in the ground state. During the formation of this compound, the 2s orbital and two 2p orbitals hybridize.
Name of the Molecule: Boron Trifluoride
Molecular Formula: BF3
Geometry: Trigonal Planar
Answer:
Explanation:
Of course Newton's three laws of motion are correct, because they were verified several hundred of years ago and they continue working today, for such systems. Science is accumulative. What modern physics has done is to constraint the range of validity of those laws.
Newtons first law of motion states that everybody continues in it rest or of uniform motion in a straight line unless an external force is applied on it.
Newtons second law of motion states that acceleration produced on a body by a force is directly proportional to the applied force and inversely proportional to the mass of body.
Newtons third law of motion states that to every action there is equal and opposite reaction.

Answer: p2 = 1.06p1
Explanation: pressure increases with temperature increase.
According to Gass law
P1/T1 = P2/T2
T1 = 20°c = 20 +273 = 293k
T2 = 40°c = 40 +373 = 313k
Therefore
P2 = P1T2/T1 = 313P2/293
P2 = 1.06P1
