The substance that conducts electricity is 
dissolved in water.
So, option A is correct one.
When the sodium chloride dissolve in water , the sodium atoms and chlorine atoms separates under the presence of water molecules and exist as sodium cation and chloride anion . Now , they are free to move around in the water as positively and negatively charged ions . This separation of charge allows the solution to conduct electricity.
The solid and solid sugar does not conduct electricity because it is not dissolve in water . Similarly, sugar dissolved in water does not conduct electricity .

Ideal gas law is valid only for ideal gas not for vanderwaal gas. Therefore, 10L of H₂S should react with 6.6L of oxygen at stanadard pressure and temperature.
<h3>
What is ideal gas equation?</h3>
Ideal gas equation is the mathematical expression that relates pressure volume and temperature.
Mathematically the relation between Pressure, volume and temperature can be given as
P×V=n×R×T
where,
P = pressure of gas
V= volume of gas
n =number of moles of gas
T =temperature of gas
R = Gas constant = 0.0821 L.atm/K.mol
At Standard temperature and pressure, 2 moles of H₂S react with 3 moles of 0₂. S0, 10L of H₂S should react with 0.66×10=6.6L of oxygen.
Therefore, 10L of H₂S should react with 6.6L of oxygen.

Answer:
Metals, non metals and metalloid
Explanation:
The bad smelling element is Sulfur, which smells like rotting eggs.
Answer:
c) Normal
Explanation:
Reflection is a phenomenon typical of light wave; it occurs when a ray of light hits the interface between two mediums, and bounces off back into the original medium, at a certain angle.
The direction of the reflected ray is determined by the law of reflection, which states that:
1) The incident ray and the reflected ray, together with the normal to the interface (the perpendicular to the interface), all lie within the same plane
2) The angle of incidence is equal to the angle of reflection:
where
is measured as the angle between the incident ray and the normal to the interface
is measured as the angle between the reflected ray and the normal to the interface
