Answer:
Option-A (XY)
Explanation:
In this problem one should focus on the number of valence electrons present in each atom. Remember that in lewis structure the dots on an atom always show the valence shell electrons. In given statement;
The,
X has one valence electron. It means that it can loose this single electron to attain the noble gas configuration i.e.
X° → X⁺ + 1e⁻
Similarly,
Y have seven valence shell electrons. Therefore, in order to complete the octet this atom will gain one electron i.e.
::Y:° + 1 e⁻ → Y⁻
Hence, we can conclude that X got stabilized by losing one electron and Y got stabilized by gaining one electron therefore, only one of each is required to form an ionic compound i.e.
<h3>
X⁺ + Y⁻ → XY</h3>
The indication from which one can determine how much of active ingredient is recovered after purification method is said to be a percent recovery.
The formula for percent recovery is:
The solubility of acetanilide in 100 ml of chloroform at
The solubility of acetanilide in 100 ml of chloroform at
Substituting the values in the above formula:
%.
Hence, the maximum percent recovery that can be achieved for the recrystallization of acetanilide from chloroform is %.
Answer: principal quantum number (n), azimuthal quantum number (l) and magnetic quantum number (m)
Explanation:
According to quantum mechanics, there are three sets of quantum numbers which accurately describes the electrons position; principal quantum number (n), azimuthal quantum number (l) and magnetic quantum number (m). These three quantum numbers are obtained from Schrödinger wave equation.
