3) Carbon-14 is constantly being produced in the upper atmosphere, and the amount is in equilibrium. As long as an organism is alive, it keeps its carbon isotopes in balance with the atmosphere, but at soon as it dies, it stops taking up new 14C, and so the geologic clock starts. You found a shell buried in sedimentary layers, which has 6% of its original 14C left. Determine the age of the shell. Show your work.

In hydrocarbon exploration, the stable carbon isotope composition of a hydrocarbon, expressed as δ13C, depends on three major factors. List these factors.

..1.. 4.. . I6 Il 7 Scenario 2 The airbags in vehicles contain a mixture of NaN,, KNO, and SiO, When a car decelerates at a rapid pace, an electrical signal goes to the gas generator inside the airbag, triggering a series of three chemical reactions: 10NAN. 10NA +2KNỎ, K,O + Na,0 + Na + SiO, - K,SiO, 10NA + 15N,(g) KO + 5Na O + N,(g) These reactions produce gas (N.) to fill the airbag and convert sodium azide (NaN,), a highly toxic substance, to alkaline silicate (K,SiO ). The quantity of NaN, must be carefully calculated to ensure that the volume of gas is adequate to fill the airbag firmly enough to protect the passenger but not overfill and cause the bag to explode. A standard airbag needs 67 L of N, (g) to properly inflate. notes
