The percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.
<h3>How to calculate percentage yield?</h3>
The percentage yield of a substance can be calculated by dividing the difference between the actual and theoretical yield by the actual yield, then multiplied by 100.
Percentage yield = (theoretical yield - actual yield)/actual yield × 100
According to this question, the actual yield of a product in a reaction was measured as 2.80 and the theoretical yield of the product for the reaction is 3.12 g.
Percent yield = (3.12g - 2.80g)/2.80 × 100
Percent yield = 11.43%.
Therefore, percentage yield of the product if the actual yield was measured as 2.80 g and the theoretical yield is measured as 3.12 g is 11.43%.

Answer:
Option B is correct.
The net ionic chemical reaction when Cu(NO₃)₂ reacts with water is
Cu²⁺(aq) + H₂O(l) ⇌ Cu(OH)¹⁺(aq) + H¹⁺(aq)
Explanation:
When ions dissolve in polar solvents (in water especially), then often attract ions of opposite signs.
Cu(NO₃)₂ dissolves into Cu²⁺ & NO₃⁻ and water contains H¹⁺ & OH⁻
The Cu²⁺ attracts the OH⁻ from water, thereby giving the Cu(OH)¹⁺ ion (with a net charge of +2-1 = +1) and the NO₃⁻ takes up the H⁺ ion.
10 electrons in an atom can have each of the 3d quantum number or sublevel designations.
<h3>What are four quantum numbers?</h3>
Quantum numbers are used to characterize the values of conserved quantities in a quantum system's dynamics in both quantum physics and chemistry.
1) The "n" sign refers to the principal quantum number. It shows how many shells there are.
2) The "l" sign indicates the azimuthal quantum number. It gives the form of the orbitals and their angular momentum. 0 to n-1 make up its range.
3) "
" stands for the magnetic quantum number. It serves as a cue for spatial orientation. The range of it is -l to +l.
4) Spin quantum number, represented by the symbol "
". It shows how the electron is spinning.
