18.2 mL of a 0.156 M solution of lead(II) nitrate are added to 26.2 mL of a 0.274 M solution of potassium iodide.
kow [346]

The mass of the Pbl2 : 1308.87

<h3>Further explanation</h3>

Given

18.2 mL of a 0.156 M Pb(NO3)2

26.2 mL of a 0.274 M KI

Reaction

Pb(NO3)2 (aq) + 2 KI (aq) - Pbl2 (s) + 2 KNO3

Required

the mass of the Pbl2

Solution

mol Pb(NO3)2 = 18.2 x 0.156 = 2.8392 mlmol

mol KI = 26.2 x 0.274 =7.1788 mol

Limiting reactant Pb(NO3)2(smaller ratio of mol : reaction coeffiecient)

mol Pbl2 based on limiting reactant (Pb(NO3)2)

From equation, mol ratio of Pb(NO3)2 : Pbl2 = 1 : 1, so mol Pbl2=mol Pb(NO3)2=2.8392

Mass Pb(NO3)2 :

\tt mass=mol\times MW\\\\mass=2.8392\times 461\\\\mass=1308.87~grams

Compounds are formed when the atoms of two or more elements are chemically combined.
yuradex [85]
Fully donating an electron results in an ionic bond, so A is the correct answer.

In comparison, B, a hydrogen bond, is a bond that forms between an H in one compound and an O, N, or F in another.  It is among the strongest of intermolecular forces, while ionic/covalent bonds are intramolecular.

C, a covalent bond, is a bond that forms when atoms share electrons instead of donating them.

How did Fizeau prove or disprove Galileo’s findings?
Elis [28]

Answer:

It is commonly believed that the Catholic Church persecuted Galileo for abandoning ... Thus Galileo did not prove the theory by the Aristotelian standards of science in his day. ... If we believe Relativity, science never *can* disprove them. ... If you correctly report the findings of Fr. Spitzer, then he is wrong.
