The previous part could be done without using the decay equation, because the ratio of original 14C14C to present 14C14C was an integer power of 1/2. Most problems are not so simple. To solve more general carbon-dating problems, you must first find the value of the decay constant for 14C14C, so that you can easily use the decay equation. Using the given half-life, 5730 yearsyears, find the value of the decay constant for 14C14C. Express your answer in inverse years to three significant figures. View Available Hint(s)

The decay constant for C14 is

Explanation:

Expression for rate law for first order kinetics is given by:

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant  

a - x = amount left after decay process  

for completion of half life:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

The decay constant for C14 is

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.

nacl or sodium chloride is an ionic compound. this is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. in this case, na (sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (na+), when chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged ( since the ions are oppositely charged, they attract.
