The number of protons and neutrons in the nucleus : 92 and 146
<h3>Further explanation</h3>
Given
Mass number = 238
Atomic number = 92
Required
Protons and neutrons
Solution
Mass number=number of protons + neutrons
Atomic number=number of protons=number of electrons
Atomic number = 92⇒number of protons=92
Number of neutrons = mass number - atomic number
Number of neutrons = 238 - 92 = 146
Not sure with the answer, but I hope this helps :/
Electrolyte is any species which when dissolved in solvent particularly water dissociates into cations and anions. Electrolytes are conductors of electricity. In given options;
CCl₄ (Tetrachloromethane) is a covalent compound. And it doesn't dissociate to any cation or anion. So it is not electrolyte.
SiO₂ (Silicon Dioxide) is also covalent in nature and exist in giant framework. It is not electrolyte.
Glucose (C₆H₁₂O₆) is also covalent compound. And doesn't produced any ion in water, hence it is not electrolyte.
H₂SO₄ (Sulfuric acid) is Electrolyte. When it is dissolved in water it produces H⁺ and SO₄²⁻ ions as follow,
H₂SO₄ → 2 H⁺ ₍aq₎ + SO₄²⁻ ₍aq₎
Result:
H₂SO₄ is electrolyte.
No idea.. I think if you take angle (<) MNL then divide those...
