FL 2 C/P

Question 1

hybridization

Answer 1

count total number of bonds and lone pair groups and minus one to get sp hybridization

Question 2

half life of radiaoctive material

Answer 2

time it takes for half of all radioactive nuclei to decay into their daughter nuclei

Question 3

venturi effect

Answer 3

oxygen pressure is the sum of the oxygen static pressure P and the oxygen flow pressure ρv2/2. In the area of the mask openings, Pair = P + ρv2/2, thus Pair > P. Air enters the mask because the static pressure of the air is larger than the static pressure of the oxygen in flow.

Question 4
