4 0
0ne mole of CuSO4.5H2O contains 6.023×10^23 no.of molecules

Again, 1 mole CuSO4.5H2O contains 9 oxygen atoms

Therefore,1 mole CuSO4.5H2O contains 9 × 6.023×10^23 no.of oxygen atoms

Hope this help!

Lead(II) nitrate, Pb(NO3)2, and potassium iodide, KI<br><br><br> net ionic equation:
MissTica

Answer:

Pb²⁺ (aq) + 2I⁻ (aq) → PbI₂ (s)

General Formulas and Concepts:

  • Solubility Rules
  • Reaction Prediction

Explanation:

<u>Step 1: RxN</u>

Pb(NO₃)₂ (aq) + KI (aq) → PbI₂ (s) + KNO₃ (aq)

<u>Step 2: Balance RxN</u>

Pb(NO₃)₂ (aq) + 2KI (aq) → PbI₂ (s) + 2KNO₃ (aq)

<u>Step 3: Ionic Equations</u>

Total Ionic Equation:

Pb²⁺ (aq) + 2NO₃⁻ (aq) + 2K⁺ (aq) + 2I⁻ (aq) → PbI₂ (s) + 2K⁺ (aq) + 2NO₃⁻ (aq)

<em>Cancel out spectator ions.</em>

Net Ionic Equation:

Pb²⁺ (aq) + 2I⁻ (aq) → PbI₂ (s)

7 Be + 2 HCl →BeCl2+ H2
Mashutka [201]

Answer:

The percent yield is 42.52%.

Explanation:

Theoretical yield of beryllium chloride = 12.7 g

Actual yield of the beryllium chloride = 5.4 g

The formula used for the percent yield will be :

\text{Percent yield}=\frac{\text{Actual yield}}{\text{Theoretical yield}}\times 100

Now put all the given values in this formula, we get:

\%(yield)=\frac{5.4 g}{12.7 g}\times 100=42.52\%

The percent yield is 42.52%.
