How many liters of O₂ are needed to react completely with 10.0 L of H₂S at STP
sergiy2304 [10]

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.
