How many grams of lead (ii) iodide will be precipitated by adding sufficient Pb(NO3)2 to trace with 630mL of 0.268M Ki solution? 2KI(aq)+Pb(NO3)2(aq) → PbI2+2KNO3(aq)

i believe that it is a exoplanet

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be

c-14 is carbon-14, or radiocarbon.   it is a radioactive isotope of carbon with an atomic nucleus containing 6 protons and 8 neutrons.
