Part a
in an automobile collision, sodium azide, nan3, decomposes and fills an air bag with nitrogen gas. if an air bag contains 1400 g of nan, (6501 g/mol),
what is the volume of nitrogen gas produced at stp? the equation for the reaction is
2nan; (s)
2na(s) + 3n2(g)

What’s the scientific notation for the number 6,840,000,000

Why is nh3 classified as a polar molecule

Acalorimeter is to be calibrated: 51.203 g of water at 55.2 degree c is added to a calorimeter containing 49.783 g of water at 23.5c. after stirring and waiting for the system to equilibrate, the final temperature reached is 37.6 degree c. specific heat capacity of water (s = 4.18 j/g∙degree c). calculate the calorimeter constant. (smδt)warm water = -[(smδt)cold water + (calorimeterδtcold water)]
