Answer:
A its a step by step equation the answer is A
Answer: the data appear to be ( linear )
The line of best fit is v= 0.003 t+ 0.003
Notice the the value of the v intercept is close to 0 so V and t are ( directly proportional)
B its viscosity decreases
Moles of NaN3 at STP = volume of gas / 22.4 = 11.5/22.4 = 0.5mole. Massof NaN3 = moles of NaN3 x molecular weight = 0.5 x 65 = 32.5 grams.
