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:
Heterogenous mixture is a mixture that has different properties throughout.
Explanation:
Mixture refers to substances that are not chemically mixed together, that is, they can easily be separated by physical methods. There are two major types of mixture; these are heterogeneous and homogeneous mixtures. Homogeneous mixtures refer to those mixtures that are uniform in composition. A good example of this is tap water. Heterogeneous mixture on the other hand refers to those mixtures, which are not uniform in composition. A good example of this is a mixture of water and sand.
Answer:
C + D
Explanation:
C + D are the reactants because they are on the right side of the equation
