Answer:
2.938 mol Pb(NO₃)₄
Explanation:
Step 1: Given data
- Moles of NH₄NO₃ to be produced: 11.75 mol
Step 2: Write the balanced equation
4 (NH₄)₃PO₄ + 3 Pb(NO₃)₄ = Pb₃(PO₄)₄ + 12 NH₄NO₃
Step 3: Calculate the number of moles of Pb(NO₃)₄required to produce 11.75 moles of NH₄NO₃
The molar ratio of Pb(NO₃)₄ to NH₄NO₃ is 3:12.
11.75 mol NH₄NO₃ × (3 mol Pb(NO₃)₄/12 mol NH₄NO₃) = 2.938 mol Pb(NO₃)₄
Answer:
2.8.8.
Explanation:
The element belonging to Group 8a and period 4 is Krypton, which has 18 electrons. The valence shell electronic configuration for the first 20 elements is 2.8.8.2 so Krypton's valence shell electronic configuration would be 2.8.8. only.
Answer:
Electrolytes are chemicals that break into ions (ionize) when they are dissolved in water. The positively-charged ions are called cations, while the negatively charged ions are called anions.
Strong electrolytes completely ionize in water. This means 100% of the dissolved chemical breaks into cations and anions.
Weak electrolytes partially ionize in water. Pretty much any dissociation into ions between 0% and 100% makes a chemical a weak electrolyte, but in practice, around 1% to 10% of a weak electrolyte breaks into ions.
If a substance doesn’t ionize in water at all, it’s a nonelectrolyte.

Answer:
The octet rule is a chemical rule of thumb that reflects the observation that main group elements tend to bond in such a way that each atom has eight electrons in its valence shell, giving it the same electronic configuration as a noble gas.
