Potassium iodide reacts with lead(II) nitrate in the following precipitation reaction: 2KI(aq)+Pb(NO3)2(aq)→2KNO3(aq)+PbI2 (s)2KI(aq)+Pb(NO3)2(aq)→2KNO3(aq)+P bI2(s) What minimum volume of 0.232 MM potassium iodide solution is required to completely precipitate all of the lead in 180.0 mLmL of a 0.105 MM lead(II) nitrate solution? Potassium iodide reacts with lead(II) nitrate in the following precipitation reaction: What minimum volume of 0.232 potassium iodide solution is required to completely precipitate all of the lead in 180.0 of a 0.105 lead(II) nitrate solution? 81.5 mLmL 40.7 mLmL 326 mLmL 163 mLmL

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.

percent abundance for cu-63 can be shown as:

63 x + 65 (1-x) = 62.9296

65 - 62.9296 = 2 x

x = 1.035

thus, percent abundance for cu-63 is 1.035

percent abundance for cu-65 can be shown as:

63 x + 65 (1-x) = 64.9278

65 - 64.9278 = 2 x

x = 0.0361

thus, percent abundance for cu-63 is 0.0361

the mass spectrum of cu-63 showing the intense peak as, this isotope is found in nature more abundantly around 92.38 % in comparison to cu-65 which is found 62.58 % naturally
